Lasix (Furosemide)

Rating of sales:          


Lasix is a highly effective FDA approved medication for the treatment of excessive edema (fluid retention) due to kidney disorder (nephrotic syndrome), heart failure, cirrhosis and liver disease. It is also used to treat high blood pressure (hypertension). Lasix works by regulating the way in which the body absorbs salts.

Bumex, Edecrin, Demadex, Sodium Edecrin, Fluss 40


Also known as:  Furosemide.


Lasix prevents excessive edema (fluid retention) in people with kidney disorder (nephrotic syndrome), heart failure, cirrhosis and liver disease. It is also used for the treatment of high blood pressure (hypertension), high levels of potassium (hyperkalemia), calcium (hypercalcemia), and magnesium (hypermagnesemia).

The active component, Furosemide, is a potent loop diuretic (water pill) that eliminates water and salt from the body. Furosemide works by blocking the absorption of sodium, chloride, and water from the filtered fluid in the kidney tubules, causing a profound increase in the output of urine (diuresis).

Lasix starts to act within one hour after oral administration, and the effect lasts for about 6-8 hours.


Lasix is available in tablets which should be taken orally with a full glass of water.

The dosage of Lasix depends on the body weight and on the health status of the recipient.

Take Lasix at the same time once a day.

Do not take more than your recommended dose, as high doses of furosemide may cause irreversible hearing loss.

Do not crush or chew the tablet.

To achieve the most effective results, do not stop taking Lasix suddenly.


In case of a Lasix overdose visit your doctor or health care provider immediately. Symptoms of a Lasix overdose include fainting, tinnitus, confusion, weakness, lightheadedness, lack of appetite.


Store at room temperature between 15 and 30 degrees C (59 and 86 degrees F) away from moisture, light and heat. Throw away any unused medicine after the expiration date. Keep out of the reach of children.

We reviewed baseline and follow-up clinical and echocardiographic data on patients receiving CRT in a single centre. Indices of global left ventricular (LV) function and dyssynchrony before and after CRT were measured. Patients were then divided into those receiving their first device (n = 39) and those receiving CRT as an upgrade to existing RV pacemakers (n = 32). Baseline demographic variables, indices of global LV function, symptomatic status, renal function, hemodynamics, and diuretic requirements were not different between previously paced patients and nonpaced patients. Mean length of RV pacing in the previously paced patients was 59 months (range 12-167 months). Patients in the previously paced group had a broader QRS complex than patients with intrinsic LBBB. Aortopulmonary delay of longer than 40 ms was present in 68% of all subjects, 67% had intraventricular septal and posterior wall motion delay longer than 130 ms, and 59% had an intraventricular delay as measured by tissue Doppler imaging of longer than 65 ms. There was no difference between paced and nonpaced patients for any of these measures of dyssynchrony. QRS duration was reduced to a greater extent in the previously paced patients than those with no previous device therapy. CRT led to important reductions in each dyssynchrony variable in both patients with previous RV pacing and those with intrinsic LBBB. The magnitude of these changes in measures of dyssynchrony was not different between the 2 groups. In all patients undergoing CRT, 50% had a reduction in furosemide dose at 3 months, 56% an improvement of at least 1 grade in New York Heart Association status, and 66% an improvement of at least 5% in LVEF. Divided by group, previously paced patients were no more or less likely than newly implanted patients to achieve one or more of these clinical outcomes.

Although PTC most frequently occurs in obese females of childbearing age, the syndrome occurs in children as well.(3),(5) Prepubertal children with PTC have a lower incidence of obesity compared with adults and there is no sex predilection. The onset of puberty is best defined by the onset of secondary sexual characteristics such has menarche, pubic hair, and breast development. Children with PTC have a higher incidence of associated conditions and cranial nerve deficits compared with adults. Similar to adult patients, children are at risk for the development of permanent visual loss. In rare instances, children initially diagnosed with PTC will be found to harbor an intracranial neoplasm such as gliomatosis cerebri. An intracranial pressure of 28 cm H2O has recently been established as the upper limit of normal in children.31 Treatment is indicated for the symptomatic management of headaches and to preserve vision. Most children respond to medications such as acetazolamide, furosemide, or topiramate. Surgical treatment such as ONSF and shunting procedures are indicated for children with severe headaches, visual loss, or both despite maximal tolerated medical treatment.

Urinary excretion of vitamin B(6), oxalic acid and vitamin C was investigated in 15 healthy subjects during maximal water diuresis and in the group of 12 patients in polyuric stage of chronic renal failure without dialysis treatment receiving a diet containing high sodium chloride (15g/day). Urinary excretions of the same parameters were investigated in another group of 15 patients in polyuric stage of chronic renal failure without dialysis treatment after i.v. administration of 20 mg furosemide. Urinary excretion of vitamin B(6), oxalic acid and vitamin C significantly increased during maximal water diuresis while during high intake of sodium chloride the urinary excretions of these substances were not affected. The results suggest that urinary excretion of vitamin B(6), oxalic acid and vitamin C depends on the urinary excretion of water. Intravenous administration of 20 mg furosemide led to an increase of urinary excretion of vitamin B(6), oxalic acid and vitamin C in patients with chronic renal failure. The increased urinary excretion of vitamin B(6) and vitamin C is a new negative side effect of furosemide and increased urinary excretion of oxalic acid is a new positive side effect in patients with chronic renal failure.

There was no significant difference in the mean change in serum creatinine level at the end of 48 h between groups (p = 0.08). There was also no significant difference among groups regarding loss of body weight (p = 0.66). A significantly shorter hospitalization was observed in patients treated with HSS compared with the other groups (cIV group 6.6 ± 3.4 days vs. bI group 7.9 ± 4.1 days vs. HSS group 3.7 ± 1.3 days; p < 0.01).

During continuous treatment with diuretics, the kidney adapts to the initial Na loss by activating antinatriuretic mechanisms which serve to prevent further Na and volume losses. To study the renal sites of adaptations to constant diuretic treatment, bendroflumethiazide (4 mg daily), furosemide (8 mg daily) or vehicle (0.24 ml daily) was infused intraperitoneally to female Wistar rats by implanted osmotic minipumps. Half of the animals (groups vol.) were randomized to receive a balanced saline solution to drink in addition to water in order to replace Na, K and volume losses. On the 6th day of treatment, clearances of inulin, Na, and Li were determined during four consecutive 6 hr periods. Circadian changes in renal excretions occurred in all groups with highest excretions of Na, Li and water in the dark period (6 p.m. to 6 a.m.). Renal changes induced by continuous infusion of diuretics were most pronounced in the dark period and would probably not have been disclosed if the clearance experiments had been restricted to the daytime. The average 24-hour clearance for inulin (glomerular filtration rate) was not different among groups, except for a 20% decrease in the furosemide group. The 24-hour fractional Na excretion, being approximately 0.5% in the vehicle group, increased to approximately 0.8% in group (bendroflumethiazide+vol) and to approximately 2.8% in group (furosemide+vol) but was not different from the vehicle group in the diuretic groups without volume replacement.(ABSTRACT TRUNCATED AT 250 WORDS)

The cardiorenal syndrome is not well understood, and a uniform definition is lacking. Worsening renal function as determined by a decline in creatinine clearance in patients with decompensated heart failure is an identifier of patients with this syndrome. Treatment is a challenge. Diuretic therapy is valuable in treating congestion but may worsen renal function. Patients with decompensated heart failure are often refractory to diuretics, in which case higher doses must be used or alternate methods explored to reduce salt and water.

In paediatrics drugs are prescribed as mg/kg doses to facilitate accurate dosing. Anecdotally, some drugs are prescribed in such a way that the volume to be given is difficult to measure which may lead to inaccuracies and potential for error. Locally, errors have been reported where there has been a misunderstanding of the required dose, especially when decimal points are involved. This audit aimed to evaluate doses prescribed for in-patient children and evaluate whether they can be measured using the printed markings of one oral syringe.

The mechanism of gamma-aminobutyric acid (GABA)-induced suppression of 5-hydroxytryptamine (5HT)-induced contractility of cerebral blood vessels was studied in single smooth muscle cells isolated from the guinea-pig basilar artery. GABA reduced 5HT-induced contraction of single smooth muscle cells, and the effect of GABA was mimicked by muscimol, but not baclofen. The response of muscimol was antagonized by bicuculline, thereby indicating that GABAA receptors exist on the smooth muscle of the basilar artery. Since GABA did not change the contraction induced by the addition of Ca2+ to the Ca2+-free medium in the presence of high K+, it is unlikely that GABA inhibits the influx of extracellular Ca2+. The caffeine-induced contraction in the Ca2+-free medium was reduced by GABA, and the effect of GABA was not obtained by treatment with furosemide and in the Cl- -free medium. These results indicate that GABA acts on the GABAA receptor located on smooth muscle cells and reduces the contractility of the basilar artery by suppression of the mobilization of intracellular Ca2+.

Contrast medium in combination with NOS and COX inhibition resulted in widespread induction of HIF in the outer and inner medulla that was initiated within 10 minutes, reached the highest levels at 2 hours and diminished 8 hours to 24 hours thereafter. HIF isoforms were expressed in a cell type-specific fashion: HIF-1alpha in tubular and HIF-2alpha in interstitial and endothelial cells. The degree of HIF-1alpha accumulation varied between nephron segments, being much stronger in collecting ducts than in medullary thick ascending limb of the loop of Henle (mTAL). Comparison with pimonidazole staining and the effect of furosemide indicated that HIF induction in mTAL is maximal with moderate hypoxia and declines with increasing severity of hypoxia.

Amplitude and phase responses of distortion product otoacoustic emissions as a function of stimulus frequency ratio were measured for frequencies between 2 and 48 kHz, in Mongolian gerbils (Meriones unguiculates) aged 15 to 30 days after birth. After baseline measurements, furosemide was administered to distinguish active from passive emissions. At all ages, structure in the form of multiple peaks was observed in the amplitude responses of specific odd-order emissions. This structure depended on the emission frequency, not the stimulus frequency ratio, and did not generally depend on the stimulus amplitude. Nor was it dependent on the functioning of the cochlear amplifier: At moderate stimulus levels, the observed emission distribution simply shifted to lower amplitudes when the cochlear amplifier was made temporarily dysfunctional by furosemide injection. The center frequencies and widths of the peaks in the amplitude response did not generally change with age, except that the relative amplitudes of the higher-frequency peaks were increased in younger animals. At 2 kHz, however, the distribution showed other evidence of maturation, with the frequency of maximum emission moving downward with age. The phase responses yielded estimates of the round trip signal (group or traveling wave) delay. At a given frequency, the active signal delay typically decreased substantially with increasing stimulus level. However, there was a rapid variation in delay as the stimulus level passed the normal active-passive crossover level. At stimulus levels measured relative to the active-passive crossover level, i.e., either 20 or 30 dB lower, the active signal delay decreased only slightly with age. Overall, both filter response and signal delay characteristics were found to be essentially mature near the onset of hearing.

Our results demonstrated that furosemide given as an adjuvant medication in patients with DTC causes a significant decrease in urinary excretion of radioiodine and its higher blood concentration. Therefore, furosemide should not be recommended as an adjuvant therapy to radioiodine ablation in patients with DTC previously iodine depleted by low-iodine diet.

The study included 34 males and 10 females from 1 to 9 months old (median age 2.6 months) with unilateral congenital hydronephrosis. A 99mtechnetium (Tc) mercaptoacetyltriglycine (MAG3) scan was performed, and regions of interest were drawn on the kidneys, and perirenal and lateral backgrounds. Differential renal function was calculated with and without background subtraction at 30-second intervals from 0.5 to 3 minutes after injection of 99mTc-MAG3. The effects of age, sex, obstruction, site and size of the hydronephrotic kidney were analyzed using the generalized estimating equations method.

In brain slices from young (postnatal day (P) 10--15) rat somatosensory cortex, real-time neuronal intracellular Cl(-) concentration ([Cl(-)](i)) recordings were made by an optical technique measuring 6-methoxy-N-ethlquinolinium iodide (MEQ) fluorescence. Oxygen--glucose deprivation (in vitro model of ischemia) induced a long-lasting [Cl(-)](i) increase preceded by a rapid, transient [Cl(-)](i) decrease that could not be inhibited by blockers of Cl(-) pumps, Cl(-) channels, or Cl(-) antiporters, but was sensitive to cation-Cl(-) cotransporter inhibitors (bumetanide and furosemide). Use of low external Na(+) or high external K(+) revealed that the Na(+),K(+)-2Cl(-) cotransporter was inhibited by bumetanide and furosemide, whereas the K(+)-Cl(-) cotransporter was preferentially inhibited by furosemide under our experimental conditions. With a reduced inward driving force for Na(+) (reducing Na(+),K(+)-2Cl(-) cotransport), the transient [Cl(-)](i) decrease was only rarely induced by oxygen-glucose deprivation. In contrast, with a reduced outward driving force for K(+) (reducing K(+)-Cl(-) cotransport), the transient [Cl(-)](i) decrease still occurred. These results suggest that the transient [Cl(-)](i) decrease was primarily mediated by a rapid inhibition of the inwardly directed Na(+),K(+)-2Cl(-) cotransporter. Reverse transcriptase-polymerase chain reaction (RT-PCR) experiments suggested that the isoform involved is NKCC1. We hypothesize that the initial rapid Cl(-) efflux might effectively delay the irreversible Cl(-) influx that mediates neuronal injury.

36Cl- uptake was markedly (85 per cent) inhibited by the loop diuretics, furosemide and bumetanide. Partial replacement of Na+ in the incubation medium (from 137 to 5 mM) reduced 36Cl- uptake 30 per cent; total replacement reduced uptake to 40-45 per cent of control values. Partial replacement of K+ (from 5.8 to 1 mM) decreased 36Cl- uptake approx. 45 per cent; complete replacement resulted in minimal levels of 36Cl- uptake (less than 10 per cent of controls). Ouabain reduced 36Cl- uptake approx. 55 per cent in the absence of bumetanide, but was without effect in its presence. 86Rb+ uptake was reduced approx. 85 per cent with bumetanide; complete replacement of Cl- with I- or gluconate-, decreased 86Rb+ uptake by 55 or 40 per cent respectively. The results support the notion that the bulk of Cl- influx in rat parotid acinar cells is via a loop diuretic-sensitive Na+/K+/Cl- co-transport mechanism as may occur in other secretory epithelia.

We microperfused the loop of Henle (LOH) to assess its contribution to urine acidification in vivo. Under control conditions (Na HCO3- = 13 mM, perfusion rate approximately 17 nl/min-1) net bicarbonate transport (JHCO3-) was unsaturated, flow- and concentration-dependent, and increased linearly until a bicarbonate load of 1,400 pmol.min-1 was reached. Methazolamide (2 x 10(-4) M) reduced JHCO3 by 70%; the amiloride analogue ethylisopropylamiloride (EIPA) (2 x 10(-4) M) reduced JHCO3 by 40%; neither methazolamide nor EIPA affected net water flux (Jv). The H(+)-ATPase inhibitor bafilomycin A1 (10(-5) M) reduced JHCO3 by 20%; the Cl- channel inhibitor 5-nitro-2'-(3-phenylpropylamino)-benzoate (2 x 10(-4) M) and the Cl(-)-base exchange inhibitor diisothiocyanato-2,2'-stilbenedisulfonate (5 x 10(-5) M), had no effect on fractional bicarbonate reabsorption. Bumetanide (10(-6) M) stimulated bicarbonate transport (net and fractional JHCO3-) by 20%, whereas furosemide (10(-4) M) had no effect on bicarbonate reabsorption; both diuretics reduced Jv. In summary: (a) the LOH contributes significantly to urine acidification. It normally reabsorbs an amount equivalent to 15% of filtered bicarbonate; (b) bicarbonate reabsorption is not saturated; (c) Na(+)-H+ exchange and an ATP-dependent proton pump are largely responsible for the bulk of LOH bicarbonate transport.

Both the commonly employed thiazide diuretics and chlorthalidone and the loop diuretics furosemide, piretanide and xipamide lead, to varying extents, to an increase in total and LDL cholesterol as well as triglycerides in subjects with normal metabolism. In addition, some diuretics lower the levels of protective HDL cholesterol. These side effects can be avoided--at least in part--by a combination with such drugs as prazosin, pindolol or captopril, which have a favorable effect on metabolism.

Few data exist to help physicians in the use of diuretics to provide the greatest symptomatic benefit with the least adverse effect to patients and to select the subset of patients who require a more aggressive diuretic strategy and monitoring. The aim of this study is to identify early predictors of diuretic response in a selected group of patients with acutely decompensated chronic heart failure (ADCHF).

Based on five randomized controlled trials (RCTs) involving 1,032 patients treated with i.v. HSS plus furosemide vs. 1,032 patients treated with i.v. furosemide alone, a decrease in all-cause mortality in patients treated with HSS plus furosemide was proven [RR = 0.57; 95 % confidence interval (CI) = 0.44-0.74, p = 0.0003]. Likewise, combined therapy with HSS plus furosemide was shown to be associated with a reduced risk of ADHF-related re-hospitalization (RR = 0.51; 95 % CI = 0.35-0.75, p = 0.001). Besides, combined therapy with HSS plus furosemide was found to be associated with a reduced length of hospital stay (p = 0.0002), greater weight loss (p < 0.00001), and better preservation of renal function (p < 0.00001).

Cell volume changes critically determine hepatic signal transduction and metabolism. Hepatocyte swelling by insulin contributes to p38(MAPK) activation leading to inhibition of autophagic proteolysis. Recently integrins were shown to sense hypoosmotic hepatocyte swelling. Here the role of integrins, Src, and focal adhesion kinase (FAK) in insulin signaling was investigated using the intact organ model of perfused rat liver. Insulin increases [Tyr(P)(418)]Src, [Tyr(P)(397)]FAK, and dual p38(MAPK) phosphorylation by about 2-fold. Infusion of the integrin-antagonizing hexapeptide GRGDSP or the Src inhibitor PP-2 prevented activation of Src and p38(MAPK) and, consequently, proteolysis inhibition by insulin. However, insulin-induced phosphorylation of IRbeta (Tyr(1158)) and protein kinase B (PKB, Ser(473)), as well as K(+)-uptake and cell swelling, was not reduced by the inhibitors. Both hypoosmotic swelling and insulin increase the plasma membrane levels of activated beta(1) integrin. Inhibition of insulin-induced swelling by furosemide largely abolished activation of beta(1) integrin and phosphorylation of Src, but not of PKB. Rapamycin does not affect either insulin-induced K(+)-retention and cell swelling or proteolysis inhibition, indicating that swelling-dependent proteolysis inhibition occurs independently from the mammalian target of rapamycin. The data suggest that sensing of cell swelling by integrins essentially contributes to insulin signaling, thereby defining a novel way of integrin involvement in growth factor signaling.

Gout is the most common type of inflammatory arthritis in man caused by deposition of urate crystals into the joints as the result of elevated serum urate levels. A case of a 59-year-old patient with untreated, long-lasting gout and clinical manifestation of decompensated global dilated cardiomyopathy is presented. Examination revealed generalized pitting edema extending from both lower extremities to the sacrum, abdominal, and thoracic wall, with scrotal swelling and upper extremity involvement, an exceptionally vast generalized edema, i.e. anasarca. Proximal and distal interphalangeal joints of the hands and feet were swollen and deformed, with marked yellow tophi nodules. Laboratory studies revealed high serum uric acid concentration (546 micromol/L), decreased creatinine clearance (0.8 mL/s) and albumin concentration (27.4 g/L), as well as increased total urine protein mass (0.35 g/24 h). X-rays of the affected feet and fists showed punched-out lesions of the subchondral bone with overhanging bony margins in the first metatarsophalangeal, proximal, and distal interphalangeal joints of both hands. The extreme clinical presentation resolved upon intravenous administration of diuretics and pleurocentesis, followed by oral medications including furosemide, angiotensin-converting enzyme inhibitor, spironolactone and digoxin. Since serum urate level has been identified as an independent risk factor for the development of ischemic heart and chronic kidney disease, regulation of urate concentration is necessary, especially in patients diagnosed with gout.

The study included 15 healthy individuals aged 37.3 +/- 7.7 years and 27 patients with the primary uncomplicated blood hypertension (stages I and II according to WHO classification) of the comparable age, untreated and given a diet containing 100-120 nM Na+ daily. Plasma ANP concentrations were measured prior to and after 30, 60, and 90 minutes following 40 mg furosemide intravenously. An increase in 1-minute urine output and 1-minute Na+ excretion in the urine were determined during 90 minutes following furosemide administration. A significant decrease in ANP plasma levels was noted in all examined individuals following furosemide administration in all time intervals comparing with baseline values. An increase in 1-minute urine output and 1-minute sodium excretion with the urine significantly correlated with plasma ANP decrease during 90 minutes following furosemide administration. The obtained results suggest that furosemide inhibits ANP secretion in the patients with uncomplicated primary hypertension similarly to healthy individuals.

Diuretics are widely used antihypertensive agents, and although their renal actions have been well characterized, the extent of their vascular effects remains to be defined. Because hypertension is associated with numerous vascular complications whose incidences are not always lowered once blood pressure is regulated, this study was undertaken to evaluate the effects of five selected diuretics on capillary permeability to see if they could contribute in some way to these vascular abnormalities. Extravasation of Evans blue dye (EB: 20 mg/kg) injected in the caudal vein of male Wistar rats was used to assess capillary permeability to albumin. Indapamide (0.04 mg/kg), cicletanine (2.0 mg/kg), amiloride (0.3 mg/kg), hydrochlorothiazide (0.5 mg/kg) and furosemide (0.5 mg/kg) were administered by acute i.v. injection or by 10-day "chronic" gavage. EB extravasation was increased in the upper bronchi, lung parenchyma and kidney after acute administration of indapamide (54, 41 and 31%, respectively) and hydrochlorothiazide (45, 41 and 19%, respectively), and increased in all tissues but the duodenum (upper bronchi, lung parenchyma, heart, liver, kidney and muscle; 57-118%) after furosemide. In contrast, capillary permeability was reduced after acute cicletanine in the heart (31%), duodenum (49%) and muscle (58%) and after amiloride in the heart (25%) and muscle (63%). Pretreatment with indomethacin abolished most changes in EB extravasation induced by acute injection of the diuretics. After 10-day gavage, however, changes in capillary permeability were null after amiloride or hydrochlorothiazide treatment, attenuated after cicletanine or furosemide or even reversed after indapamide. Arterial pressure was not affected by diuretic treatment.(ABSTRACT TRUNCATED AT 250 WORDS)

Autosomal dominant hypocalcemia type 1 (ADH1) is a relatively rare endocrine disorder characterized by hypocalcemia and inadequate parathyroid hormone secretion. ADH is caused by activating mutations in the calcium-sensing receptor (CaSR) gene, CASR. CaSR plays a crucial role in calcium and magnesium homeostasis in the kidney. ADH may be accompanied by hypokalemia and metabolic alkalosis when it is classified as type V Bartter syndrome. However, the mechanism underlying hypokalemia in this disease is unclear.

The exploitation of hot-melt extrusion and injection molding for the manufacturing of immediate-release (IR) tablets was preliminarily investigated in view of their special suitability for continuous manufacturing, which represents a current goal of pharmaceutical production because of its possible advantages in terms of improved sustainability. Tablet-forming agents were initially screened based on processability by single-screw extruder and micromolding machine as well as disintegration/dissolution behavior of extruded/molded prototypes. Various polymers, such as low-viscosity hydroxypropylcellulose, polyvinyl alcohol, polyvinyl alcohol-polyethylene glycol graft copolymer, various sodium starch glycolate grades (e.g., Explotab(®) CLV) that could be processed with no need for technological aids, except for a plasticizer, were identified. Furthermore, the feasibility of both extruded and molded IR tablets from low-viscosity hydroxypropylcellulose or Explotab(®) CLV was assessed. Explotab(®) CLV, in particular, showed thermoplastic properties and a very good aptitude as a tablet-forming agent, starting from which disintegrating tablets were successfully obtained by either techniques. Prototypes containing a poorly soluble model drug (furosemide), based on both a simple formulation (Explotab(®) CLV and water/glycerol as plasticizers) and formulations including dissolution/disintegration adjuvants (soluble and effervescent excipients) were shown to fulfill the USP 37 dissolution requirements for furosemide tablets.

A renal unit was defined as a kidney and its ureter. There were 262 renal units with 4 patients having a solitary kidney. 90 normal and 172 abnormal renal units on sonography were assessed by F+0 diuresis renography. The furosemide clearance half time for the 90 normal renal units was 5.8 +/- 1.4 min. Of the 172 abnormal renal units, 100 were classified as nonobstructed and 72 as obstructed on diuresis renography. All 100 nonobstructed renal units were correctly classified with no false-negative studies; of the 72 renal units classified as obstructed, there were 43 true-positive studies and 29 false-positive studies. The sensitivity was 100%, specificity was 78% and accuracy was 83%.

The magnesium loading test is a useful tool in the diagnosis of magnesium deficiency. In order to establish a reference range in normal subjects, 88 healthy men and women aged between 18 and 66 years were given 30 mmol magnesium intravenously during eight hours as a loading test, urine was collected from start of infusion for 24 h for measurement of magnesium excretion. The magnesium mean retention was 6.3 +/- 10.3% of the loading dose, and the 0.025 and 0.975 fractiles were -19.5% and 27.5%, respectively. There was no significant difference between the sexes or in the different age groups studied. There was no correlation between the magnesium retention and serum magnesium or with basal urinary magnesium excretion. An excess excretion of magnesium was observed the postload day compared to baseline, but the excretion 24 and 48 h after the magnesium loading were closely correlated, suggesting that 24 h urinary sampling is sufficient. In order to examine the reproducibility of the test 23 of the subjects underwent two magnesium loading tests 4 weeks apart. The mean difference between two repeat magnesium loading tests was 2.0% with a SD of 8.1% and a 95% confidence interval of -1.6-5.5%. Normal saline did not affect baseline magnesium excretion. Concomitant administration of ethanol or physical exercise caused greater variation in magnesium excretion, whereas furosemide was without effect. The 8 h magnesium loading test with 24 h urine sampling seems to be fairly reproducible, is adequate for clinical use, but the normal range is wide.

Allergy to furosemide is a rare phenomenon. Desensitization to this sulfa-containing drug has not been frequently performed. We describe a patient with severe congestive heart failure and type I allergy to furosemide. Because of the severity of her condition, we decided to use a rapid intravenous desensitization protocol. Following the desensitization, the patient was treated with intravenous and oral furosemide with a dramatic improvement in her clinical state. We suggest that rapid desensitization may be a safe and effective way of introducing furosemide to allergic patients for whom loop diuretics are urgently indicated.

After a mean follow-up of 28 months, two patients showed isolated biochemical recurrence and six patients remained free of recurrence. In seven patients with functional allografts, the creatinine clearance was unimpaired by treatment. However, significant obstruction of the terminal ureter was revealed in two patients by furosemide-stimulated diethylenetriaminepentaacetic acid renograms. The doses delivered to the uretero-neocystostomy were calculated to range from less than 20 Gy to more than 45 Gy depending on bladder repletion.

Telmisartan 1-O-acylglucuronide, the principal metabolite of telmisartan in humans, was characterized in terms of chemical stability and the structure of its isomerization products was elucidated. In addition, pharmacokinetics of telmisartan 1-O-acylglucuronide were assessed in rats after i.v. dosing. Similar to other acylglucuronides, telmisartan 1-O-acylglucuronide and diclofenac 1-O-acylglucuronide, which was used for comparison, showed the formation of different isomeric acylglucuronides on incubation in aqueous buffer. The isomeric acylglucuronides of telmisartan consisted of the 2-O-, 3-O-, and 4-O-acylglucuronides (alpha,beta-anomers). First order degradation half-lives of 26 and 0. 5 h were observed on incubation in buffer of pH 7.4 for the 1-O-acylglucuronides of telmisartan and diclofenac, respectively. This indicated that the 1-O-acylglucuronide of telmisartan was among the most stable acylglucuronides reported to date. The high stability of telmisartan 1-O-acylglucuronide was confirmed by in vitro experiments that indicated only very low covalent binding of telmisartan acylglucuronide to human serum albumin but a considerable amount of covalently bound radioactivity with the acylglucuronide of diclofenac. After i.v. dosing to rats, telmisartan 1-O-acylglucuronide was rapidly cleared from plasma with a clearance of 180 ml/min/kg, compared with 15.6 ml/min/kg for the parent compound. Because telmisartan 1-O-acylglucuronide exhibited a comparably high chemical stability together with a high clearance that resulted in low systemic exposure, the amount of covalent binding to proteins should be negligible compared with other frequently used drugs, such as furosemide, ibuprofen, or salicylic acid.

The capacity of aging rats to defend body buy lasix online fluid homeostasis in response to a variety of dipsogenic and natriorexigenic stimuli was assessed. Male and female rats of both the Fischer 344 (FR) and Sprague-Dawley (SD) strains were used and tested at target ages of approximately 5, 10, 15, and 20 mo in both longitudinal and cross-sectional studies. There were no consistent age-related declines in water intake in response to water deprivation or acute administration of hypertonic NaCl; angiotensin (ANG) I, II, III; or isoproterenol. Likewise, there were no major impairments in either urinary excretion of the hypertonic NaCl load or excretion of water or hypotonic NaCl loads, although the latter were excreted more slowly in the older cohorts. The preference/aversion functions for NaCl solutions differed between SD and FR rats, but did not change with age except in male FR rats that lost their aversion to dilute NaCl at 20 mo of age. Intake of hypotonic NaCl solution after acute sodium depletion (furosemide treatment) showed a partial decline with age, and the older rats sustained larger estimated sodium deficits after a 6-h repletion period. A more complete age-related decline was observed in the intake of hypertonic NaCl stimulated by chronic dietary administration of a kininase II inhibitor (ramipril). Male rats of 15-20 mo of age showed no ramipril-induced sodium appetite. Brain ANG II receptor density, determined by autoradiography, declined by almost 50% in the paraventricular nucleus at 20 mo of age and declined slightly in the organum vasculosum laminae terminalis but did not decline in either the supraoptic nucleus or subfornical organ. Thus the major deficits in fluid intake in aging rats are related to salt appetite; the mechanism was not identified definitively.

The binding of frusemide was studied in the plasma of 20 healthy subjects and 45 patients with liver disease. The unbound percentage (mean +/- s.d.) of frusemide was 1.64 +/- 0.21 healthy subjects) and 2.24 +/- 0.79 (patients) (P less than 0.01). By grouping the buy lasix online patients on the basis of plasma albuminaemia and bilirubinaemia four clusters namely: 'normal concentrations of albumin and bilirubin' (A), 'hyperbilirubinaemia and normal albumin concentration' (B), 'hypoalbuminaemia and normal bilirubin concentration' (C) and 'hypoalbuminaemia and hyperbilirubinaemia' (D) were defined. The unbound percentage of frusemide was 1.80 +/- 0.36 in (A); 2.44 +/- 1.05 in (B); 2.23 +/- 0.38 in (C); 2.76 +/- 0.77 in (D). The figure for healthy volunteers was not different from A, whereas it was significantly lower than those for B and D (P less than 0.01) and for C (P less than 0.05). A lowered binding of frusemide was associated with hypoalbuminaemia or hyperbilirubinaemia.

Thiazide diuretics have been shown to decrease bone loss and improve bone mineral density, while long-term furosemide therapy has been suggested to decrease bone mineral content. However, the direct effects of these diuretics on osteoblastic cells are not well established. Some investigators have reported direct effects of thiazides on osteoblastic cells but the results remain controversial, and there are few data about the direct effect of furosemide on osteoblastic cells. We investigated the effects of hydrochlorothiazide (HCTZ) and furosemide on proliferation, alkaline phosphatase activity, osteocalcin, and interleukin-6/interleukin-11 (IL-6/IL-11) secretion in cultured normal human bone marrow stromal osteoprogenitor cells (hBMSCs). Treatment with HCTZ or furosemide for 24 hours in the concentration range of buy lasix online 10(-6) to 10(-4) mol/L did not affect 3H-thymidine incorporation in hBMSCs. Cellular alkaline phosphatase activity and osteocalcin production were not changed significantly by treatment with HCTZ or furosemide (up to 10(-4) mol/L) during culture. There was also no significant difference in IL-6 and IL-11 production in hBMSCs. These results suggested that HCTZ or furosemide had no significant direct effect on proliferation, alkaline phosphatase activity, osteocalcin, and IL-6/IL-11 production in hBMSCs, and the effects of these diuretics on bone mass may be related to the indirect action on calcium balance.

Similar volumes were removed in UC and UF groups (110105 mL and 107415 mL, respectively) and the UF group also produced 45325 mL of urine. Na concentration was 138±6 meq/L in the ultrafiltrate, 85±73 meq/L in the UC group's urine, and 26±23 meq/L in the UF group's urine. Given the relevant associated volumes, total buy lasix online meq of the Na removed was similar (1168 in UC vs. 1216 in UF). The UF group produced isotonic ultrafiltrate and a higher volume of dilute urine than anticipated.

We examined the role of the subfornical organ (SFO) in stimulating thirst and salt appetite using two procedures that initiate water and sodium ingestion within 1-2 h of extracellular fluid depletion. The first procedure used injections of a diuretic (furosemide, 10 mg/kg sc) and a vasodilator (minoxidil, 1-3 mg/kg ia) to produce hypotension concurrently with hypovolemia. The resulting water and sodium intakes were inhibited by intravenous administration of ANG II receptor antagonist (sarthran, 8 micrograms . kg(-1). min(-1)) or angiotensin-converting enzyme inhibitor ( buy lasix online captopril, 2.5 mg/h). The second procedure used injections of furosemide (10 mg/kg sc) and a low dose of captopril (5 mg/kg sc) to initiate water and sodium ingestion upon formation of ANG II in the brain. Electrolytic lesions of the SFO greatly reduced the water intakes, and nearly abolished the sodium intakes, produced by these relatively acute treatments. These results contrast with earlier findings showing little effect of SFO lesions on sodium ingestion after longer-term extracellular fluid depletion.

Tolvaptan induced aquaresis with an increase in free water clearance, resulting in a buy lasix online significant increase in serum sodium concentrations and a decrease in cumulative water balance. Tolvaptan also decreased pulmonary capillary wedge pressure without affecting systemic vascular resistance, glomerular filtration rate or renal blood flow. Tolvaptan tended to increase plasma arginine vasopressin concentrations but did not affect plasma renin activity. In contrast, furosemide induced clear saluresis with increased electrolyte excretion, resulting in decreased pulmonary capillary wedge pressure. However, furosemide also decreased serum potassium concentration and increased plasma arginine vasopressin concentrations and plasma renin activity.

Since in whole animal studies and in man the renal clearance of cimetidine was prolonged by the coadministration of probenecid, the aim of the present study was to examine the interaction of the organic base cimetidine with the organic anion transport system at the basolateral membrane of isolated non-perfused rabbit proximal tubules. S2 segments of proximal tubules were incubated at 37.5 degrees C with 3H-cimetidine (2 x 10(-7) mol/l) or 3H-PAH (4 x 10(-6) mol/l, as a marker for the organic anion transport system) and 14C-inulin (marker for the extracellular space) for 25 min to achieve a steady state. Afterwards, a nonradiolabelled substance was added to the bath, and the change of the cellularly stored radioactivity was measured at 5-min intervals. Probenecid (5 x 10(-5) mol/l) decreased the cellular amount of 3H-cimetidine to 26% of the control value. At this concentration, furosemide and Na2SO4 had no effect. At a concentration of 10(-3) mol/l, these substances reduced the cellular 3H-cimetidine uptake to 33% (furosemide) and 57% (Na2SO4) of the control value. 10(-4) and 10(-3 Suprax Brand Name ) mol/l succinate diminished the steady-state uptake of cimetidine to 77% and 53% of the control value, respectively. On the other hand, cimetidine (10(-3) mol/l) decreased the cellular uptake of 3H-PAH to 52% of the control value. N1-methylnicotinamide (5 x 10(-5) mol/l and 10(-3)mol/l) had no effect on the steady-state uptake of 3H-PAH. These results indicate that the organic base cimetidine, besides its high affinity for the cation transporter, also interacts with the organic anion transport system at the basolateral membrane of rabbit proximal tubules.

This study was designed to test the hypotheses that furosemide directly causes relaxation in human fetal airway Cialis 15 Mg and that delivery of loop diuretics to either the adventitial or epithelial surface of newborn mouse airway results in equivalent relaxation. Isometric tension changes were measured in human fetal (11-16 wk) trachea and mainstem bronchus rings exposed to furosemide (300 microM) or saline after acetylcholine or leukotriene D(4) constriction. Significant decreases in isometric tension to furosemide were demonstrated after constriction with acetylcholine or leukotriene D(4). To examine the site of effect and mimic aerosolized and systemic administration, furosemide (3-300 microM) and bumetanide (0.3-30 microM) were applied separately to epithelial and adventitial surfaces of newborn mouse airways. No differences in airway diameter changes to epithelial or adventitial furosemide or bumetanide were observed, but a 10-fold difference in potency was found. In summary, human fetal airway relaxed to furosemide when constricted with either neurotransmitter or inflammatory mediator in vitro. Further, no differences in relaxation to equimolar epithelial and adventitial furosemide were observed in isolated newborn mouse airway. Taken together, this provides evidence that furosemide has a direct, nonepithelial-dependent effect on airway smooth muscle tone.

Inhalation of the loop diuretic furosemide has been found to protect against challenges with bronchoconstrictive agents. OBJECTIVE: To determine if furosemide has any objective and/or subjective therapeutic effect on adult patients with acute exacerbations of asthma, above and beyond the effects of B2 agonists and oral glucocorticoids. METHODS: 35 adult patients with acute exacerbations of asthma were randomized and recruited into the study if they had a prior history of asthma, and <10 pack-year smoking history, had not received pre-hospital B2 agonists, were not pregnant, and had no sulfonamide allergy. A double blind study design was employed. One group received albuterol 5 mg with placebo and one group received albuterol 5 mg with furosemide 40 mg in their nebulizer. Both groups received prednisone 80 mg po. PEFRs were obtained before initiation of treatment and 30 and 60 minutes thereafter. A 10 point dyspnea scale was also employed at initiation of treatment and 30 and 60 minutes thereafter. Physicians were permitted to give rescue albuterol treatments as deemed necessary. RESULTS: There was no difference in Zoloft Overdose Hallucinations the treatment arms with respect to PEFR, dyspnea score, or number of rescue albuterol treatments at 30 and 60 minutes. CONCLUSIONS: We found no statistical benefit to adding furosemide to a regimen consisting of prednisone and optimal doses of B2 agonist. We conclude that there is not a current role for furosemide in acute exacerbations of asthma.

On Day 3 following MI, the development of subclinical acute kidney injury was identified through significantly increased serum and urine neutrophil gelatinase-associated lipocalin level. We detected the increase of activated monocytes (CC chemokine receptor 2(+) ED-1(+)) in peripheral blood, along with the infiltration of ED-1(+) macrophages and the increment of nuclear p65 in the kidney of MI rats, suggesting the contribution of nuclear factor-kappa B-mediated inflammation in the development of Type 1 cardiorenal syndrome (CRS). The inflammatory cytokines, interleukin-6 and tumour necrosis factor-α (TNF-α) mRNA expression, as well as microvascular endothelial permeability and tubular cell apoptosis, significantly increased in the kidneys of MI rats. At 4 and 8 weeks after MI, tubular cell apoptosis, ED-1(+) macrophage infiltration and interstitial fibrosis increased in MI rats, and these chronic changes were significantly mitigated by systemic monocyte/macrophage depletion using liposome clodronate.

Furosemide, a diuretic, is frequently administered to horses for the prophylaxis of exercise-induced pulmonary hemorrhage and the treatment of a number of clinical conditions, including acute renal failure and congestive heart failure. Furosemide increases the rate of urinary sodium, chloride, and hydrogen ion excretion. Plasma potassium concentration decreases after furosemide administration but urinary potassium excretion in horses is minimally affected. Renal blood flow increases after furosemide administration. Systemically, furosemide increases venous compliance and decreases right atrial pressure, pulmonary artery pressure, pulmonary artery wedge pressure, and pulmonary blood volume. The systemic hemodynamic effects of furosemide are only manifest in the presence of a functional kidney, but can occur in the absence of diuresis, emphasizing the importance of the renal-dependent extra-renal effects of furosemide. The renal and systemic hemodynamic effects of furosemide are modified by prior administration of nonsteroidal anti-inflammatory drugs. Furosemide administration attenuates exercise-induced increases in right atrial, aortic, and pulmonary artery pressures in ponies. Furosemide prevents exercise and allergen-induced bronchoconstriction in humans and decreases total pulmonary resistance in ponies with recurrent obstructive airway disease. These pharmacologic effects are frequently used to rationalize its questionable efficacy in the prevention of exercise-induced pulmonary hemorrhage. Neither the effect of furosemide on athletic performance nor its efficacy in the prevention of exercise-induced pulmonary hemorrhage has been convincingly demonstrated.

Three-hour infusions of angiotensin II (ANG II) agonists and antagonists were used to determine the relative sites of action of ANG in producing water drinking and salt appetite. In the first experiment, lateral ventricular (LV) but not fourth ventricular (4V) ANG II elicited water and saline intake, and LV but not 4V sarile, a competitive ANG II receptor blocker, reduced saline intake aroused by ip injections of 10 mg/kg furosemide and 6 mg/kg captopril. In the second experiment, water, but not saline, intake to furosemide-captopril treatment was reduced by sarile infusions into the subfornical organ (SFO). It is concluded that (a) brain ANG receptors for water and saline intakes are more accessible from the forebrain than the hindbrain ventricles and (b) receptors for water drinking, but not saline intake, after captopril reside in part in the SFO. Salt appetite appears to be dependent on ANG II receptors somewhere in the forebrain other than in the SFO.

Direct myocardial transplantation of HFDSCs by open-chest surgical procedure was performed in 10 patients with HF due to nonischemic, nonchagasic dilated cardiomyopathy. Before and after the procedure, and with no changes in their preoperative doses of medications (digoxin, furosemide, spironolactone, angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, betablockers), patients were assessed for New York Heart Association (NYHA) class, performance in the exercise tolerance test (ETT), ejection fraction (EF), left ventricular end-diastolic dimension (LVEDD) via transthoracic echocardiography, performance in the 6-minute walk test, and performance in the Minnesota congestive HF test. All 10 patients survived the operation. One patient had a stroke 3 days after the procedure, and although she later recovered, she was unable to perform the follow-up tests. Another male patient experienced pericardial effusion 3 weeks after the procedure. Although it resolved spontaneously, the patient abandoned his control tests and died 5 months after the procedure. An autopsy of the myocardium suggested that new young cells were present in the cardiomyocyte mix. At 40 months, the mean (+/-SD) NYHA class decreased from 3.4 +/- 0.5 to 1.33 +/- 0.5 (P = .001); the mean EF increased 31%, from 26.6% +/- 4% to 34.8% +/- 7.2% (P = .005); and the mean ETT increased 291.3%, from 4.25 minutes to 16.63 minutes (128.9% increase in metabolic equivalents, from 2.46 to 5.63) (P < .0001); the mean LVEDD decreased 15%, from 6.85 +/- 0.6 cm to 5.80 +/- 0.58 cm (P < .001); mean performance in the 6-minute walk test increased by 43.2%, from 251 +/- 113.1 seconds to 360 +/- 0 seconds (P = .01); the mean distance increased 64.4%, from 284.4 +/- 144.9 m to 468.2 +/- 89.8 m (P = .004); and the mean result in the Minnesota test decreased from 71 +/- 27.3 to 6 +/- 5.9 (P < .001).

Furosemide is the most common diuretic drug used in horses. Furosemide is routinely administered as IV or IM bolus doses 3-4 times a day. Administration PO is often suggested as an alternative, even though documentation of absorption and efficacy in horses is lacking. This study was carried out in a randomized, crossover design and compared 8-hour urine volume among control horses that received placebo, horses that received furosemide at 1 mg/kg PO, and horses that received furosemide at 1 mg/kg IV. Blood samples for analysis of plasma furosemide concentrations, PCV, and total solids were obtained at specific time points from treated horses. Furosemide concentrations were determined by reversed-phase high-performance liquid chromatography with fluorescent detection. Systemic availability of furosemide PO was poor, erratic, and variable among horses. Median systemic bioavailability was 5.4% (25th percentile, 75th percentile: 3.5, 9.6). Horses that received furosemide IV produced 7.4 L (7.1, 7.7) of urine over the 8-hour period. The maximum plasma concentration of 0.03 microg/mL after administration PO was not sufficient to increase urine volume compared with control horses (1.2 L [1.0, 1.4] PO versus 1.2 L [1.0, 1.4] control). There was a mild decrease in urine specific gravity within 1-2 hours after administration of furosemide PO, and urine specific gravity was significantly lower in horses treated with furosemide PO compared with control horses at the 2-hour time point. Systemic availability of furosemide PO was poor and variable. Furosemide at 1 mg/kg PO did not induce diuresis in horses.

We evaluated the comparative effects of furosemide, a short-acting loop diuretic, and azosemide, a long-acting loop diuretic, on neurohumoral factors and quality of life (QOL) in patients with congestive heart failure (CHF). Twenty-five stable patients with mild chronic CHF who had been administered furosemide (n = 14) or azosemide (n = 11) orally for more than 3 months were studied. We changed furosemide to azosemide or azosemide to furosemide and followed for 3 months. Echocardiography was performed, and we also measured neurohumoral factors and assessed QOL by questionnaire. Blood pressure, body weight, renal function and echocardiographic findings were the same during the furosemide and azosemide treatments. Plasma levels of atrial natriuretic peptide and brain natriuretic peptide were not different between the two treatments. However, plasma concentrations of active renin and norepinephrine were significantly higher with furosemide treatment than with azosemide treatment. QOL score was significantly lower with azosemide than with furosemide. These findings suggest that long-acting loop diuretics may have fewer adverse effects on the neuroendocrine system and QOL than short-acting loop diuretics in patients with mild CHF.

Bradykinin contracts human isolated small bronchi through prostanoid release and subsequent TP receptor stimulation. Furosemide 10(-4) to 10(-3) M concentration dependently inhibited bradykinin- and the stable TP receptor agonist U-46619-induced contraction of human isolated small airways. The inhibitory effect of furosemide on U-46619-induced contraction involves competitive antagonism at TP receptors. Such an inhibition of TP receptors could a least partly explain the inhibitory effect of furosemide on bradykinin-induced contraction, and could be one of the mechanisms of the protective effect of furosemide in asthma.

Dilated cardiomyopathy (DCM) refers to a group of conditions of diverse etiology in which both ventricles are enlarged with reduced contractility. Certain correctable conditions associated with ventricular dysfunction can masquerade as DCM. Most of them can be identified with relatively inexpensive and readily available tests. A typical diagnostic work-up for a child with DCM also includes a number of investigations to identify the underlying cause, some of which are expensive and sophisticated. The average center in the developing world often does not have the facilities to carry out these investigations. The results of many of these investigations typically do not translate into a specific management strategy that makes a difference to prognosis. A significant number of children with DCM will eventually develop end-stage heart failure that requires cardiac transplantation with or without bridging procedures. This is an unrealistic option for the developing world. The management strategy of childhood DCM in the developing world needs to be tailored to the resources available with in a manner such that the overall prognosis is not substantially affected.

This is the first reported case of furosemide-associated bilateral angle-closure glaucoma. Similar idiosyncratic reactions following exposure to other sulphonamide-containing drugs have been described. We propose discontinuation of the offending agent and treatment with oral prednisone in similar clinical settings.

Overall ninety patients (thirty in each group) were included in the study. There was a greater diuresis in first 24 h (p = 0.002) and a shorter hospital stay (p = 0.023) with the bolus group. There was no significant difference in renal function and serum sodium and serum potassium levels. There was no difference in the number of emergency department visits among the three groups.

Clinical seizure activity prior to ECMO and the duration of ECMO therapy are independently associated with SNHL. These data confirm that there is an increased incidence of SNHL in neonatal ECMO survivors at 9-13 years of age and suggest that SNHL may also present later in childhood in this patient population. Upon recovery from acute respiratory failure and after discharge from the hospital, longitudinal neurodevelopmental follow-up of infants treated with ECMO during the neonatal period is essential.

CsA, rofecoxib, and their combination lowered the furosemide-induced increase of prostaglandin E(2) (PGE(2)) and of 6-keto prostaglandin F(1 alpha) (6-keto PGF(1 alpha)) excretion by 55% and by 70%. They also lowered furosemide stimulated renal excretion of sodium and water by about 65% and 60%. Basal as well as furosemide-induced stimulation of plasma renin activity (PRA) and of renal renin mRNA was further enhanced by CsA. In contrast, rofecoxib attenuated the furosemide-induced rise of PRA and of renin mRNA, both in the absence and in the presence of CsA. In addition, the increase in plasma 6-keto PGF(1 alpha) levels by furosemide was further enhanced by CsA and was attenuated by rofecoxib.

Pediatric cases of vitamin D intoxication (VDI) with dietary supplements have not been previously reported. We report on 7 children with VDI caused by consumption of a fish oil supplement containing an excessively high dose of vitamin D due to a manufacturing error. Seven children aged between 0.7 and 4.2 years were admitted with symptoms of hypercalcemia. Initial median (range) serum concentrations of calcium and 25-hydroxyvitamin D were 16.5 (13.4-18.8) mg/dL and 620 (340-962) ng/mL, respectively. Repeated questioning of the parents revealed use of a fish oil that was produced recently by a local manufacturer. Analysis of the fish oil by gas chromatography/mass spectrometry revealed that the vitamin D3 content was ~4000 times the labeled concentration. Estimated daily amounts of vitamin D3 intake varied between 266,000 and 800,000 IU. Patients were successfully treated with intravenous hydration, furosemide, and pamidronate infusions. With treatment, serum calcium returned to the normal range within 3 days (range: 2-7 days). Serum 25-hydroxyvitamin D levels normalized within 2 to 3 months. Complications, including nephrocalcinosis, were not observed throughout the 1-year follow-up. In conclusion, errors in manufacturing of dietary supplements may be a cause of VDI in children. Physicians should be aware of this possibility in unexplained VDI cases and repeatedly question the families about dietary supplement use. To prevent the occurrence of such unintentional incidents, manufacturers must always monitor the levels of ingredients of their products and should be rigorously overseen by governmental regulatory agencies, as is done in the pharmaceutical industry.
