Androgen excess disorders--acne, alopecia, and hirsutism--can be treated effectively with endocrine therapy such as androgen receptor blockers or antagonists, or with androgen suppression. Spironolactone, estrogen, and dexamethasone are considered the most effective approaches to treatment. Whatever the modality, careful planning is key to success, with recognition that response rates vary from patient to patient. A treatment regimen generally continues for at least 2 years.

Analyses were done on 55 patients treated with spironolactone and 56 patients treated with placebo. Significant reductions of office systolic BP (-8.9±6.7 mmHg, P=0.012), 24-h ABPM systolic BP (-7.9±7.2 mmHg, P=0.032) and ABPM day-time systolic BP (-7.5±7.1 mmHg) after 8 weeks of spironolactone treatment, compared to placebo, were only observed in patients with a median age>62 years. The office and ABPM systolic BP reductions in patients aged ≤62 years and diastolic BP reductions by spironolactone in both age groups were not significant compared to placebo. Women tended to have a nonsignificantly higher reduction in systolic BP with spironolactone treatment, and there was no difference in diastolic BP reduction between women and men.

Medical treatment with a mineralocorticoid receptor (MR) antagonist, which has produced spontaneous remission of bilateral primary aldosteronism (PA), may also produce spontaneous remission of unilateral PA, for which laparoscopic adrenalectomy is recommended. However, few reports exist regarding spontaneous remission after MR antagonist therapy in unilateral PA.

Patients with congestive heart failure (CHF) often have increased aldosterone activity that leads to hypomagnesemia. Hypomagnesemia can induce arrhythmias, an important cause of death in patients with CHF. We determined whether the aldosterone receptor antagonist spironolactone improved magnesium homeostasis and reduced arrhythmias in patients with CHF.

The pharmacokinetics and bioavailability of IS-5-MN after single-dose oral and intravenous application were investigated over 24 h in three patients with liver cirrhosis and compared with normal subjects. The analysis of IS-5-MN in plasma was carried out using a gas-chromatographic method with electron capture detection. A two-compartment open model was taken as a basis for the calculations of the plasma concentration curves and the pharmacokinetic parameters. First results show that plasma concentrations after intravenous administration in the patient group were not higher than in the control group. After oral administration the peak concentrations of IS-5-MN were also no higher, nor did they occur earlier, in patients with liver cirrhosis than in the normal subjects. Our data also show the same complete absolute bioavailability of IS-5-MN in the patient group as in normal subjects, and the same elimination half-life of the plasma concentration response curve. We saw no influence of typical comedication, i.e., cimetidine or spironolactone on pharmacokinetic parameters in the group of liver patients.

Heart failure (HF) is the only cardiovascular disease with increasing incidence and prevalence. Most HF patients are older adults. With the aging of the population and effective treatment of hypertension and coronary artery disease, the two major underlying causes of HF, the number of older Americans with HF is expected to rise significantly in the coming decades. HF is the number one hospital discharge diagnosis for older adults. It is one of the causes of frequent hospital readmissions, reflecting acute decompensation and compromised quality of life for patients and increased cost and resource use for the healthcare system. It is also associated with approximately 300,000 deaths annually, most in older adults. Advances in the management of HF in the past several decades have significantly decreased the mortality and morbidity associated with this condition. Randomized controlled trials have demonstrated the beneficial effects of angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers, beta-blockers, and spironolactone on survival and quality of life of HF patients, but there is evidence of underuse of evidence-based care for HF. Several national guidelines have been published since 1994 that recommended evidence-based evaluation and management of HF. In 1995, the American College of Cardiologists (ACC) and the American Heart Association (AHA) published their first HF guidelines that recommended left ventricular (LV) function evaluation for all patients presenting with HF and use of ACE inhibitors for all patients with LV systolic dysfunction (LVSD) unless contraindicated. The guidelines recommended the use of hydralazine and isosorbide dinitrate in patients who could not use ACE inhibitors. In addition, digoxin was recommended in patients with HF due to LVSD but not adequately responsive to ACE inhibitors and diuretics and in those with atrial fibrillation and rapid ventricular rates. Diuretic use was recommended for symptomatic patients with evidence of fluid overload. Use of anticoagulation was restricted to patients with atrial fibrillation or to those with a history of systemic or pulmonary embolism. Beta-blockers were reserved for HF patients after acute myocardial infarctions. Recent advances in the management of HF called for a revision of the guidelines.

We retrospectively examined 170 patients with prior MI. The primary end point was cardiac death or hospitalization for heart failure. During a mean follow-up period of 6.4 ± 2.9 years, 37 patients developed the primary end point. Univariate Cox proportional hazards regression analyses showed that age, male gender, chronic kidney disease, anterior wall MI, number of leads with fQRS, left ventricular ejection fraction, loop diuretic use, and spironolactone use were significantly associated with the primary end point. A multivariate Cox proportional hazards regression analysis selected age (hazard ratio [HR] 1.09, 95% confidence interval [CI] 1.04-1.14, p<0.001) and the number of leads with fQRS (HR 1.33, 95% CI 1.11-1.60, p=0.002) as predictors of the primary end point. A receiver operating characteristic curve analysis showed that the presence of ≥3 leads with fQRS was most useful for distinguishing between patients with and without the primary end point. A Kaplan-Meier analysis showed a lower primary event-free rate in patients with ≥3 leads with fQRS than in those with <3 leads with fQRS.

During phase A, mean SBP decreased from baseline by 8 mm Hg, and diastolic blood pressure (DBP) decreased by up to 3.8 mm Hg; no dose-response relationship was demonstrated. Mean differences in SBP from placebo during phase B were -2.61 for the low-dose group, +2.32 for the middle-dose group, and -2.76 mm Hg for the high-dose group; only the reduction in the high-dose group was statistically significant (P = .048). No significant effects on DBP of eplerenone therapy relative to placebo were detected. Eplerenone was well tolerated, with a rate of adverse events comparable to that of placebo.

Treatment-resistant depression patients show both reduced glucocorticoid receptor function and a hyperactive hypothalamic-pituitary-adrenal axis. However, few studies have examined the role of the mineralocorticoid receptor. This study aimed to evaluate the functional activity of the mineralocorticoid receptor system in regulating the hypothalamic-pituitary-adrenal axis in well-defined treatment-resistant depression patients.

At 12 months, the increase in mean total cholesterol levels was greater in the OC+SPL group than in the OC group (27% vs. 13%, respectively; p=.02). The increase in mean sex hormone-binding globulin levels was greater in the OC group than in the OC+SPL group (424% vs. 364%, respectively; p=.01). No statistically significant differences between the groups were found for any of the other variables.

Spironolactone is a renal competitive aldosterone antagonist. One of its most important metabolite is the 7α-methylthio spironolactone: thus it is very important to have an efficient and safe access to this compound, for pharmacokinetic studies. In this context, we synthesized this metabolite by thioalkylation of 7α-thio spironolactone using Hünig's base with a very good yield. We also used our procedure to prepare, with an easy work-up and high yields, 7α-thioether and thioester derivatives of spironolactone, that could be useful for further Structure-Activity Relationships studies.

Treatment with spironolactone (SPL) is beneficial in patients with severe congestive heart failure (CHF). In the Randomized Aldactone Evaluation Study SPL was well tolerated, particularly with regard to renal function and serum K(+) levels. Our aim was to investigate whether the reported low frequency of adverse effects during SPL treatment in a heart failure study population could be confirmed in an unselected heart failure outpatient cohort and to identify potential predictors of harmful effects.

The relation between breast cancer and selected nonestrogenic drugs was evaluated in the Group Health Cooperative of Puget Sound, Seattle, Washington, a prepaid health care organization with computerized information on diagnoses and outpatient drug use. No important positive associations with breast cancer were found in a follow-up study of 302 women aged 35-74 years. These women were newly diagnosed with breast cancer in 1977-1980 and were studied in relation to exposure in the six months prior to diagnosis to one or more of the following drugs: diazepam, digitalis glycosides, medroxyprogesterone acetate, methyldopa, metronidazole, phenothiazines, tricyclic antidepressants, thiazides, thyroid/levothyroxine sodium, or spironolactone. A modest association between recent reserpine use and breast cancer was present (risk ratio = 1.7, 90% confidence interval 0.9-3.3).

Our experimental study showed that in a dose related manner SP has successful inhibitory effect on the rat uterine horn, and also on the smooth muscle organs; ileum and trachea. We guess that SP can be used in well regulated dosed with least side effects to arrest preterm labor on human being in the future. Up to date there is no manuscript about contraction inhibitory effect of SP on the uterus. We hope this study will be of scientific help.

aldactone 10 mg 2017-10-22

This review reports our own experience with, and literature studies of, the pharmacological management of hirsutism in women with hyperandrogenism (polycystic ovary syndrome) or with normal serum androgen levels and regular ovulatory menstrual cycles (idiopathic hirsutism). Treatment consists of suppressing ovarian or adrenal androgen secretion, or blocking androgen actions in the skin. The major drugs used are gonadotropin-releasing hormone (GnRH) agonists, combined oral contraceptives (COCs), and steroidal (cyproterone acetate and spironolactone) or nonsteroidal (flutamide and finasteride) antiandrogens. GnRH agonists, suppressing the pituitary, decrease androgen and estradiol secretion and improve severe hirsutism. To avoid estrogen deficiency problems, 'add back' therapy with estrogen-progestogen or COCs is advisable. This method of treatment is complicated and expensive, limiting its use to severe forms of ovarian hyperandrogenism with hyperinsulinemia. The third-generation COCs, containing new progestogens or cyproterone, have very restricted effectiveness in the short term (6 cycles), but their long term use (> 12 cycles) cures mild-to-moderate hirsutism and improves severe hirsutism. As well as suppressing gonadotropins and ovarian androgen steroidogenesis, these formulations decrease free testosterone levels and may also decrease adrenal androgen production. In women being treated with antiandrogens, COCs are important to provide control of the menstrual cycle and contraception. Cyproterone, a progestational agent, inhibits gonadotropin secretion and blocks androgen action. It is used in COCs or in a reverse sequential regimen. In the latter, it is very effective in the short term treatment of hirsutism. Spironolactone blocks androgen receptors. Its effectiveness in hirsutism is dosage-dependent: low dosages are less active than other antiandrogens, whereas high dosages (200 mg/day) are very effective at the cost of buy aldactone online several adverse effects (particularly dysfunctional uterine bleeding), but the concomitant use of a COC may prevent these. Flutamide is a pure antiandrogen that blocks androgen receptors and inhibits hair growth. It is very effective in treating hirsutism within 6 to 12 months. Dry skin is very frequent during treatment with flutamide, and hepatotoxicity is possible at high dosages. Finasteride, a 5 alpha-reductase type 2 inhibitor, is the least effective antiandrogen, but a dosage of 5 mg/day decreases hirsutism without adverse effects. Pregnancy must be avoided during therapy with antiandrogens because of the possible risk of abnormal development of a male fetus. Antiandrogens, especially flutamide (250 to 500 mg/day) and cyproterone (12.5 to 50 mg/day in a reverse sequential regimen), alone or in association with COCs, seem to be the most effective agents for the treatment of hirsutism.

The possibility of an inhibitory effect of spironolactone on the biliary clearance of digoxin has been investigated in 6 healthy subjects. Plasma clearance and the renal and biliary clearance of digoxin were determined twice at steady state (digoxin 0.5 to 1 mg.d-1 p.o. for 6 days), alone or in combination with spironolactone 200 mg daily, after an intravenous dose of digoxin (0.7 x oral dose) on Day 7. Plasma and urine were collected for 48 h. Biliary clearance of digoxin was determined on Day 8 by a duodenal perfusion technique. During spironolactone treatment plasma digoxin clearance tended to be lower (255 vs 224 ml/min; P = 0.057) and renal clearance significantly lower (166 vs 144 ml/min buy aldactone online ), while the biliary clearance of digoxin remained unchanged (106 vs 103 ml/min). Thus, spironolactone reduced the renal clearance of digoxin by an average of 13%, without affecting its biliary clearance.

Aldosterone concentrations vary in advanced chronic renal failure (CRF). The isozyme 11beta-hydroxysteroid dehydrogenase 2 (11beta-HSD2), which confers aldosterone specificity for mineralocorticoid receptors in distal tubules and collecting ducts, has been reported to be decreased or normal in patients with renal diseases. Our objective was to determine the role of aldosterone and 11beta-HSD2 renal microsome activity, normalized for glomerular filtration rate (GFR), in maintaining K+ homeostasis in 5/6 nephrectomized rats. Male Wistar rats weighing 180-220 g at the beginning of the study were used. Rats with experimental CRF obtained by 5/6 nephrectomy (N = 9) and sham rats (N = 10) were maintained for 4 months. Systolic blood pressure and plasma creatinine (Pcr) concentration were measured at the end of the experiment. Sodium and potassium excretion and GFR were evaluated before and after spironolactone administration (10 for 7 days) and 11beta-HSD2 activity on renal microsomes was determined. Systolic blood pressure (means +/- SEM; Sham = 105 +/- 8 and CRF = 149 +/- 10 mmHg) and Pcr (Sham = 0.42 +/- 0.03 and CRF = 2.53 +/- 0.26 mg/dL) were higher (P < 0.05) while GFR (Sham = 1.46 +/- 0.26 and CRF = 0.61 +/- 0.06 mL/min) was lower (P < 0.05) in CRF, and plasma aldosterone (Pald) was the same in the two groups. Urinary sodium and potassium excretion was similar in the two groups under basal conditions but, after spironolactone treatment, only potassium excretion was decreased in CRF rats (sham = 0.95 +/- 0.090 (before) vs 0.89 +/- 0.09 microEq/min (after) and CRF = 1.05 +/- 0.05 (before) vs 0.37 +/- 0.07 microEq/min (after); P < 0.05). 11beta-HSD2 activity on renal microsomes was lower in CRF rats (sham = 0.807 +/- 0.09 and CRF = 0.217 +/- 0.07 protein-1; P < 0.05), although when normalized for mL GFR it was similar in both groups. We conclude that K+ homeostasis buy aldactone online is maintained during CRF development despite normal Pald levels. This adaptation may be mediated by renal 11beta-HSD2 activity, which, when normalized for GFR, became similar to that of control rats, suggesting that mineralocorticoid receptors maintain their aldosterone selectivity.

The authors report the case of an 80-year-old man who had heavily pretreated castration refractory carcinoma of the prostate and heart failure. Following the introduction of spironolactone to manage his heart failure, buy aldactone online the patient experienced clinical and biochemical progression of his prostate cancer. Within 2 weeks of withdrawing spironolactone the patient's prostate-specific antigen returned its previous level. This is the first reported case of clinical and biochemical progression of prostate cancer following the introduction of spironolactone. The authors propose that spironolactone is a selective androgen receptor modulator. Spironolactone should be used in caution with men with prostate cancer, and should not be used to treat oedema, hypokalaemia and hypertension associated with the newly licensed hormonal therapy abiraterone acetate.

Gynecomastia is a relatively common physical finding in men. A wide variety of drugs have been implicated in its cause. Sufficient evidence in the literature suggests that calcium-channel blockers, cancer chemotherapeutic agents, and histamine2-receptor blockers may play a role in the disorder. Evidence for digitalis glycosides and neuroleptic agents is insufficient. Ketoconazole and spironolactone can also produce gynecomastia, buy aldactone online and data for marijuana are contradictory. Large numbers of drugs have only case reports of temporal association with the disorder.

Unnephrectomized, Sprague-Dawley rats were given 1% NaCl (salt buy aldactone online ) to drink and randomized to receive treatment for 28 days: vehicle infusion (control); 0.75 microg/hour aldosterone subcutaneous infusion; or aldosterone infusion + 100 mg/kg/day oral dose of eplerenone. Blood pressure and urinary albumin were measured and kidneys were evaluated histologically. Renal injury, inflammation, and fibrosis were assessed by immunohistochemistry, in situ hybridization, and reverse transcription-polymerase chain reaction (RT-PCR).

The expression of aldosterone synthase (CYP11B2), mineralocorticoid receptors (MRs), 11beta-hydroxysteroid dehydrogenase 2 (11beta-HSD2), serum- and glucocorticoid-inducible protein buy aldactone online kinase 1 (SGK1), and connective tissue growth factor (CTGF) mRNA was evaluated by reverse transcriptase-polymerase chain reaction (RT-PCR). To determine the role of reactive oxygen species (ROS) induced by aldosterone, an active oxygen assay with several inhibitors was used. The ability of RPFs to produce aldosterone was examined by enzyme immunoassay. Small interfering RNA (siRNA) of SGK1 was transfected into cultured cells using lipofectamine.

We studied the combined effect of subpressor amounts of angiotensin and long-term sodium chloride infusion on arterial pressure in 16 dogs for periods of 2--8 weeks. In dogs receiving 3.5 liters of isotonic NaCl daily, but no angiotensin, the arterial pressure increased an average of only 3 mm Hg. When angiotensin was infused continuously at a rate of 5 ng/kg per min (a rate too small to cause an observable immediate increase in pressure, subsequent infusion of 3.5 liters of saline daily then increased the pressure by 39 mm Hg. The urinary output of sodium increased to the same extent in both instances, that is, there was no extra sodium loss because of the elevated pressure. This suggests that buy aldactone online the angiotensin significantly blocked the normal "pressure natriuresis" usually seen with such large increases in pressure. However, the plasma aldosterone levels during angiotensin infusion were not found to be different from those in the absence of angiotensin. Therefore, we have suggested that the tendency of the kidneys to retain sodium under the influence of angiotensin was probably caused mainly by a direct effect of angiotensin on the kidney itself. Such a direct renal sodium-retaining effect also could be a contributing factor in the marked hypertension that results from salt administration in the presence of small amounts of angiotensin.

Glucocorticoids affect cellular and molecular events in brains by modulating the expression of many genes during stress. In the present study, we examined the regulatory effect of corticosterone on the expression and function of the norepinephrine transporter (NET) in vitro. The results show that exposure of SK-N-BE(2)C cells to corticosterone for 14 days significantly increased mRNA (up to 43%) and protein (up to 71%) levels of NET in the concentration-dependent manner. Longer exposure (21 days) resulted in greater increases in the levels of mRNAs (up to about 160%) and proteins (up to about 250%) of the NET. The up-regulatory effect of corticosterone on NET expression lasted a persistent period after cessation of exposure. Associated with the corticosterone-induced enhancement in NET expression, there was a parallel increase in the uptake of [(3)H]norepinephrine by SK-N-BE(2)C cells. Increased NET expression and function were abolished after exposure of cells to corticosterone in combination with mifepristone or spironolactone, two specific antagonists of corticosteroid receptors. This is consistent with the hypothesis that corticosterone-induced NET up-regulation is mediated by corticosteroid receptors. Nevertheless, there was no synergistic effect for a combination of both corticosteroid receptor antagonists. A similar up-regulation of NET protein levels was also observed after exposing PC12 cells to corticosterone. The present findings demonstrate that corticosterone up-regulates the expression and function of NET in vitro, indicating the action of corticosterone on the noradrenergic phenotype may play an important role in buy aldactone online the correlation between stress and the development of depression.

Diuretics may be classified according to their chemical structure, their mechanism and site of action within the nephron, and their diuretic potency. Those agents with primary action in the proximal nephron include the carbonic anhydrase inhibitors, e.g. acetazolamide, a sulfonamide derivative. Other drugs containing the sulfonamido grouping, e.g. furosemide, chlorothiazide and metolazone, also have secondary effects on the proximal nephron. Those drugs which have their major pharmacologic activity within the ascending limb of the loop of Henle, inhibiting the sodium/potassium/2 chloride electroneutral transport system, include the sulfonamide agents furosemide, bumetanide, piretanide and torasemide, and the phenoxyacetic acid derivative, ethacrynic acid. In the early portion of the distal convoluted tubule, sodium chloride reabsorption is impaired by the thiazide group, indapamide buy aldactone online and metolazone, as their primary site of action. In the late reaches of the distal convolution and in the collecting duct, agents that inhibit the exchange of sodium for that of hydrogen and potassium have their major sites of activity. These agents, spironolactone, amiloride and triamterene, differ not only chemically but in their mechanisms of action. Diuretics may also be grouped according to potency. The loop of Henle agents are the most powerful, causing the excretion of 20-25% of filtered sodium load. The thiazide group and metolazone are moderately potent, resulting in the excretion of 5-8% of filtered sodium, and the 'potassium-sparing' drugs are only mildly potent, causing the excretion of only 2-3% of filtered sodium.

Myocardial ischemia-reperfusion leads to significant changes in redox state, decreased postischemic functional recovery, and cardiomyocyte apoptosis, with development and progression of heart failure. Ischemia-reperfusion in the isolated perfused rat heart has been used as a model of heart failure. Clinically, mineralocorticoid receptor blockade in heart failure decreases morbidity and mortality versus standard care alone. The effects of corticosteroids on infarct area and apoptosis were determined in rat hearts subjected to 30 minutes of ischemia and 2.5 hours of reperfusion. Both aldosterone and cortisol increased infarct area and apoptotic index, an effect half-maximal between 1 and 10 nM and reversed by spironolactone. Dexamethasone and mifepristone aggravated infarct area and apoptotic index, similarly reversed by spironolactone. Spironolactone alone reduced infarct area and apoptotic index below ischemia-reperfusion alone, in hearts from both intact and adrenalectomized rats. The present study shows that cardiac damage is aggravated by activation of mineralocorticoid receptors by aldosterone or cortisol or of glucocorticoid receptors by dexamethasone. Mifepristone unexpectedly acted as a glucocorticoid receptor agonist, for which there are several precedents. Spironolactone protected cardiomyocytes via inverse agonist activity at mineralocorticoid receptors, an effect near maximal at a relatively low dose (10 nM). Spironolactone acts not merely by excluding corticosteroids from mineralocorticoid receptors but as buy aldactone online a protective inverse agonist at low concentration. Mineralocorticoid receptor antagonists may, thus, provide an additional therapeutic advantage in unstable angina and acute myocardial infarction.

The announcement from the Mayo Clinic in 1949 of the dramatic effectiveness of cortisone in the treatment of rheumatoid arthritis stimulated tremendous interest in steroid chemistry, endocrinology, and related areas of medicine. Shortly thereafter, G. D. Searle & Co. initiated a major effort in steroid research, the objective of which was to discover better steroid drugs than those available at that time or steroids that could be Protonix Oral Medication used for conditions for which no compounds were previously available. This effort was remarkably successful and resulted in the introduction of several important pioneering drugs. These included norethandrolone, marketed in 1956 as Nilevar, the first anabolic agent with a favorable separation between protein building and virilization, and spironolactone, introduced in 1959 as Aldactone, the first steroid antialdosterone antihypertensive agent. Of special importance was the research that culminated in the discovery of Enovid. This substance, a combination of the progestin norethynodrel and the estrogen mestranol was first approved in 1957 for the treatment of a variety of disorders associated with the menstrual cycle. The era of oral contraception began in May 1960, when Enovid was approved by the Food and Drug Administration for ovulation inhibition, and was immediately thereafter introduced for such use.

1. Mild secondary hyperaldosteronism was induced in ten healthy young males by a low sodium diet for 14 days. After 7 days on the diet, five subjects each were treated with spironolactone (group S) or triamterene (group T) daily. 2. The daily negative sodium balance was identical during the first 3 days of medication with both drugs but sodium loss was more severe during the following days in group S. Consequently, the plasma renin activity was higher during the last days Aricept 20 Mg of spironolactone compared with triamterene medication. 3. Changes in plasma electrolytes were similar in both groups. 4. No influence of either drug on the synthesis chain leading to cortisol was observed. 5. Plasma concentrations of deoxycorticosterone and corticosterone, however, increased considerably in group S, whereas triamterene did not influence these steroids. 6. Whereas triamterene induced a prompt increase of plasma aldosterone, an increase was delayed for the first 3 days of treatment with spironolactone. Later, plasma aldosterone concentrations rose rapidly in group S and were no longer different from those in group T. 7. Results are interpreted as being due to an initial inhibition of aldosterone synthesis by spironolactone, which is finally compensated, at least in part, by increased activation of the renin-angiotensin system.

The recently synthesized progesterone (P) derivatives, 18-vinylprogesterone (18VP) and 18-ethynylprogesterone (18EP), are potent inhibitors of aldosterone synthesis by adrenal glands. To evaluate the potential interest of these compounds as antihypertensive drugs, we determined whether they also interact with renal mineralocorticosteroid receptors (MR) in kidney and, if so, whether they mimic or antagonize aldosterone action. For this purpose, we evaluated the potency of 18VP and 18EP 1) to displace [3H]aldosterone binding in cytosolic fractions of kidney from adrenalectomized rats and 2) to interfere with aldosterone-induced stimulation of Na(+)-K(+)-ATPase in the collecting tubule of adrenalectomized rats. The properties of 18VP and 18EP were Tricor Order Form compared with those of their precursor progesterone and of the antimineralocorticosteroid spironolactone. The binding of [3H]aldosterone was restricted to cytosolic MR by presaturating glucocorticosteroid receptor with RU 38486. All compounds tested displaced [3H]aldosterone binding with the following efficiency: spironolactone greater than aldosterone greater than P greater than 18VP greater than 18EP; apparent Kd varied between 0.66 and 16.4 nM. Spironolactone, P, and 18VP antagonized aldosterone-induced stimulation of Na(+)-K(+)-ATPase in the collecting tubule, whereas 18EP mimicked the mineralocorticosteroid action. The different steroids tested altered Na(+)-K(+)-ATPase stimulation and aldosterone binding with the same order of potency.

Mineralocorticoid hormones, specifically aldosterone, have been shown to be increasingly important in the development and maintenance of cardiovascular disorders, particularly hypertension and congestive heart failure. The use of the mineralocorticoid receptor blocker, spironolactone, has been fraught with side effects, largely related to the poor specificity of this agent. Eplerenone, a new and more specific mineralocorticoid receptor blocker with little effect on sex-hormone receptors, has offered an alternative approach. Many studies in hypertension as well as a major and compelling study Inderal Tablets in congestive heart failure have documented the efficacy and specificity of eplerenone with a minimum of side effects. The major findings with this new agent are presented herein.

The effectiveness of the antiandrogen flutamide in combination with an oral contraceptive was studied in 20 patients with moderate to severe hirsutism. Eight patients had no previous therapy, whereas 12 had failed to respond to oral contraceptives, spironolactone, or dexamethasone therapy. Treatment with the antiandrogen flutamide (250 mg twice daily) and an oral contraceptive (Ortho 1/35) resulted in a particularly rapid and marked decrease in the total hirsutism score, which reached the normal range at 7 months. Seborrhea, acne, and hair loss score were also rapidly corrected. Treatment was associated with a decrease in plasma luteinizing hormone, progesterone, and estradiol levels. Plasma sex hormone-binding globulin levels were initially low in 18 to 20 patients but increased significantly during therapy. No clinically significant side effects were observed.

In a population of subjects with uncontrolled hypertension in which an adrenal cause is suspected, achieving a first-line abdominal CT leads to adrenal abnormality observed in 64% of patients while a specific biological abnormality is noted in 29% of subjects. This study shows that assessment that starts with an abdominal CT scan allows to indicate treatment with spironolactone more frequently than when the first assessment is limited to a biological investigation.

The effect of treatment with alpha-mercapto-beta-(2-furyl)acrylic acid (MFA), N-(N-mercaptopropionyl) glycine (MPG) and N-acetylcysteine (NAC) compared to spironolactone (SPL), a steroid, before and after 203 mercury (II) exposure, on the disposition of Hg and induction of tissue metallothionein (MT), was investigated in rats. The pretreatment with SPL, MFA and MPG enhanced faecal elimination of Hg and reduced its accumulation in liver particularly, the "heat stable fraction" resulting in lowered hepatic MT induction. Neither the renal uptake of Hg nor induction of tissue MT was affected by pre-treatment with the chelating agents; SPL and MFA causing re-distribution of Hg among the renal sub-cellular fractions. The post-Hg exposure treatment with MFA enhanced the faecal and MPG the urinary excretion of Hg. However, both the chelating agents increased the hepatic burden of Hg as reflected in the subcellular fractions and increased MT contents indicating mobilization of Hg from other tissue binding sites. The post-treatment with MPG however, depleted renal Hg as reflected by the sub-cellular distribution, without affecting renal MT levels. The results show that MFA and MPG are more promising preventive than therapeutic agents in Hg intoxication acting as metal chelators.

Dexamethasone (DXA) maximally increased the amounts of PAI-1 mRNA and protein at 100 nM. Aldosterone (Ald) increased PAI-1 expression dose dependently, but the effect was over 100-fold weaker than that of DXA. The PAI-1-increasing effects of DXA and Ald were abolished completely by U-486, a specific inhibitor of the glucocorticoid receptor (GR) but not by spironolactone, a specific inhibitor of the mineralocorticoid receptor. The effect of DXA was also blocked partially by AG1478 and herbimycin A, tyrosine kinase inhibitors. DXA further increased TNF-alpha-stimulated PAI-1 expression via the GR. Although TNF-alpha treatment caused an 80% reduction in the gene expression of HSD2, an inactivator of GCs, HSD2 inhibition did not enhance DXA-induced PAI-1 production.

Aldosterone binds to the mineralocorticoid receptor and has an important regulatory role in body fluid and electrolyte balance. It also influences a variety of different cell functions such as oxidative stress, inflammation and organ fibrosis. The important role of the tissue-specific mineralocorticoid receptors in cardiovascular and renal injury has been shown in knockout animals and in clinical studies Mineralocorticoid receptor antagonists seem to exert their beneficial effects via anti-oxidative, anti-inflammatory and anti-fibrotic effects. Spironolactone and eplerenone were the first steroidal mineralocorticoid receptor antagonist. The established steroidal mineralocorticoid receptor antagonists show important therapeutic effects but are hampered by a variety of side effects, most importantly clinically significant hyperkaliemia. Selective non-steroidal mineralocorticoid receptor antagonists have been recently developed and demonstrate effectiveness in early clinical trials. Finereroneholds promise for the future application of this new mineralocorticoid receptor antagonist class in patients with chronic kidney disease since it has shown a significant reduction in UACR combined with a safety profile similar to that in the placebo group. However, further long-term studies investigating relevant clinical end points like reduction in cardiovascular or renal event rate are warranted.

Ascites in patients with cirrhosis of the liver frequently is refractory to diuretic treatment. It was postulated that vasoconstriction of the renal cortex, mediated by activation of the renin-angiotensin-aldosterone-system (RAAS), may be one course of the disturbed sodium- and water-excretion in these patients. We therefore investigated in 14 cirrhotic patients with ascites under constant diuretic treatment the effects of low-dose captopril therapy on urinary sodium- and potassium-excretion, body weight, abdominal girth, serum-sodium, -potassium, creatinine-clearance, plasma-renin-activity (PRA), plasma-aldosterone (PA) and mean arterial pressure (MAP). After a control period of 4 days the patients received 2 x 6.25 mg/d captopril for 5 days and 4 x 6.25 mg/d for further 5 days. Treatment was followed by a second control period without captopril. PRA increased significantly after 2 days of captopril treatment. 2 x 6.25 mg/d captopril induced a significant increase in sodium excretion and a significant decrease of body weight. MAP decreased slightly but significantly without clinical signs of hypotension. 4 x 6.25 mg/d captopril resulted in a further reduction of body weight and a further enhancement of sodium excretion. Three days after withdrawal of captopril sodium output was significantly reduced again.

Medical treatment in congestive heart failure has been largely improved during the last 15 years. Treatment of left ventricular systolic dysfunction using angiotensin-converting-enzyme inhibitor is now confirmed in all NYHA classes, due to the important reduction in morbi-mortality. Betablockers have to be systematically associated in symptomatic classes. Among other drugs, only spironolactone has been shown efficient in severe NYHA classes. Diuretics in case of congestive symptoms, digoxin in order to reduce the frequency of hospitalization, and nitrates as adding therapy in severe classes may be also prescribed. However, treatment of left ventricular diastolic dysfunction remains under debate since up to date, no medication has shown a confirmed efficacy.

Published articles on human randomized trials involving specialized heart failure disease-management programs in all languages were searched using Medline from 1966 to 1999 and other online databases using the following terms and Medical Subject Headings: case management (exp); comprehensive health care (exp); disease management (exp); health services research (exp); home care services (exp); clinical protocols (exp); patient care planning (exp); quality of health care (exp); nurse led clinics; special clinics; and heart failure, congestive (exp). In addition, a manual search of the bibliographies of searched articles was performed to identify articles otherwise missed in the above search. Personal communications were made with three authors to obtain further data on their studies. Using a data abstraction tool, two of the investigators separately abstracted data from the selected articles. Data from the selected studies were combined using the DerSimonian and Laird random effects model and the Mantel-Haenszel-Peto fixed effects model. Meta-Analyst 0.998 software (J. Lau, New England Medical Center, Boston, MA) was used to determine risk ratios (RRs) with 95% confidence intervals (CIs) of mortality and hospitalization for patients receiving care through these specialized programs compared with those receiving usual care. The Cochran Q test was used to test heterogeneity among the studies, and sensitivity analyses were performed to examine the effect of various covariates, such as duration of intervention, and other characteristics of the disease-management programs.

The first clinical and scientifically confirmed description of familial pseudohypoaldosteronism is reported in 5 patients, one of whom is an adult. The rarity of the disorder may be over-estimated. The 5 patients described had anextreme liking for salt which they had consumed in large amounts and tolerated without any side effects, regardless of the quantity and the period of time involved. The results of sodium balance and othr studies carried out several months are reported. Several investigations are normal (effect of spironolactone, DOCA) supporting the evidence to data against a decreased sensitivity of the distal renal tubule to aldosterone and presenting new evidence in favour of impaired proximal tubular resbsorption of sodium; persistent hypercalcuria occurred and histological changes were maximal in the proximal tubule. The 5 patients described despite apparent clinical well-being all had biological hypoaldosteronism, and some of them a chronic salt losing state without detectable renal impairment. These findings suggest that the long-term evolution of the disease has to be reconsidered.
