We have investigated the effect of intracellular calcium levels for membrane potential during noradrenaline application in isolated small arteries. Rat mesenteric small arteries were mounted for isometric tension measurement. Smooth muscle membrane potentials were measured by conventional intracellular electrodes, and intracellular calcium concentration was measured using Fura-2 fluorescence. Under control conditions, noradrenaline caused contraction and depolarization from -55.5 to -29.3 mV. In intact arteries, depleting intracellular calcium stores with thapsigargin caused smooth muscle hyperpolarization and inhibited contraction to noradrenaline. In de-endothelialized vessels, thapsigargin still depleted calcium stores, but did not affect either the depolarization or contraction caused by noradrenaline. In noradrenaline-activated vessels, inhibition of calcium influx by amlodipine caused tension and calcium levels to fall to near-baseline levels, but membrane potential returned by only 55%. Treatment with a combination of thapsigargin, D-600 and BAPTA-AM inhibited the tension and calcium responses to noradrenaline, but the membrane potential response was reduced by only 34%. Acute reduction of extracellular chloride concentration caused similar, small depolarization at rest and during noradrenaline exposure. It is concluded that an elevation of intracellular calcium concentration is not essential for noradrenaline depolarization, although part of the depolarization is associated with the raised intracellular calcium level.

Eight weeks of amlodipine treatment significantly reduced the levels of total cholesterol, low-density lipoprotein cholesterol and triglycerides in the group on the hypercholesterolaemic diet (p < 0.05). In the blood, the level of thiobarbituric acid-reactive substances increased in the rabbits on the 2% cholesterol diet (group 2) and 2% cholesterol-plusamlodipine diet (group 4) and decreased in the amlodipineonly group (group 3) (p < 0.05). Lipid peroxidation in the heart tissue was similar to that in the blood, except in the amlodipine-only group (group 3). In the blood, the activity of total SOD (tSOD) decreased in the group on the 2% cholesterol diet (group 2) (p < 0.05) and markedly increased in the amlodipine-only (group 3) and 2% cholesterol-plusamlodipine groups (group 4) (p < 0.05).

In a multicenter, double-blind, parallel study 828 elderly (aged > or =60 years) hypertensives were randomized to lercanidipine 10 mg/day (n = 420), amlodipine 5 mg/day (n = 200), or lacidipine 2 mg/day (n = 208) (ratio 2:1:1). If blood pressure (BP) control was unsatisfactory (systolic BP/diastolic BP > or =140/90 mm Hg), the dose of the double-blind medication was doubled and, as a further step, enalapril or atenolol (plus diuretic, if needed) was added. Patients were treated for an average of 12 months.

Although end-stage renal disease (ESRD) currently affects only a small percentage (<0.2%) of the US population, its precursor, the mild and moderate forms of chronic kidney disease (CKD), affects 11% of the population, with significant growth in both ESRD and CKD anticipated in the rapidly aging US population. The primary diagnoses in the majority of ESRD patients are diabetes and hypertension. Results of clinical studies demonstrate that the level of proteinuria and sympathetic activation contribute to the progression of CKD to ESRD. There are sufficient clinical data to demonstrate that the dihydropyridine calcium channel blocker (DHP CCB) class of antihypertensives such as amlodipine and nifedipine, although effective in reducing systemic hypertension, lack activity in reducing proteinuria or attenuating sympathetic activity. Experimental studies and a limited number of clinical studies suggest that non-DHP CCBs, including verapamil and diltiazem, have a mechanism of action that differs from DHP CCBs. Non-DHP CCBs could potentially attenuate sympathetic activity and reduce protein excretion in patients with CKD.

Angiotensin-converting enzyme inhibitors (ACEI) have a well-established role in the prevention of cardiovascular events in hypertension, left ventricular dysfunction, and heart failure. More recently, ACEI have been shown to prevent cardiovascular events in individuals with increased cardiovascular risk, where hypertension, left ventricular dysfunction, or heart failure was not the primary indication for ACEI therapy.

In 2010, the American College of Medical Toxicology (ACMT) established its Case Registry, the Toxicology Investigators Consortium (ToxIC). All cases are entered prospectively and include only suspected and confirmed toxic exposures cared for at the bedside by board-certified or board-eligible medical toxicologists at its participating sites. The primary aims of establishing this Registry include the development of a realtime toxico-surveillance system in order to identify and describe current or evolving trends in poisoning and to develop a research tool in toxicology. ToxIC allows for extraction of data from medical records from multiple sites across a national and international network. All cases seen by medical toxicologists at participating institutions were entered into the database. Information characterizing patients entered in 2012 was tabulated and data from the previous years including 2010 and 2011 were included so that cumulative numbers and trends could be described as well. The current report includes data through December 31st, 2012. During 2012, 38 sites with 68 specific institutions contributed a total of 7,269 cases to the Registry. The total number of cases entered into the Registry at the end of 2012 was 17,681. Emergency departments remained the most common source of consultation in 2012, accounting for 61 % of cases. The most common reason for consultation was for pharmaceutical overdose, which occurred in 52 % of patients including intentional (41 %) and unintentional (11 %) exposures. The most common classes of agents were sedative-hypnotics (1,422 entries in 13 % of cases) non-opioid analgesics (1,295 entries in 12 % of cases), opioids (1,086 entries in 10 % of cases) and antidepressants (1,039 entries in 10 % of cases). N-acetylcysteine (NAC) was the most common antidote administered in 2012, as it was in previous years, followed by the opioid antagonist naloxone, sodium bicarbonate, physostigmine and flumazenil. Anti-crotalid Fab fragments were administered in 109 cases or 82 % of cases in which a snake envenomation occurred. There were 57 deaths reported in the Registry in 2012. The most common associated agent alone or in combination was the non-opioid analgesic acetaminophen, being reported in 10 different cases. Other common agents and agent classes involved in death cases included ethanol, opioids, the anti-diabetic agent metformin, sedatives-hypnotics and cardiovascular agents, in particular amlodipine. There were significant trends identified during 2012. Abuse of over-the-counter medications such as dextromethorphan remains prevalent. Cases involving dextromethorphan continued to be reported at frequencies higher than other commonly abused drugs including many stimulants, phencyclidine, synthetic cannabinoids and designer amphetamines such as bath salts. And, while cases involving synthetic cannabinoids and psychoactive bath salts remained relatively constant from 2011 to 2012 several designer amphetamines and novel psychoactive substances were first reported in the Registry in 2012 including the NBOME compounds or "N-bomb" agents. LSD cases also spiked dramatically in 2012 with an 18-fold increase from 2011 although many of these cases are thought to be ultra-potent designer amphetamines misrepresented as "synthetic" LSD. The 2012 Registry included over 400 Adverse Drug Reactions (ADRs) involving 4 % of all Registry cases with 106 agents causing at least 2 ADRs. Additional data including supportive cares, decontamination, and chelating agent use are also included in the 2012 annual report. The Registry remains a valuable toxico-surveillance and research tool. The ToxIC Registry is a unique tool for identifying and characterizing confirmed cases of significant or potential toxicity or complexity to require bedside care by a medical toxicologist.

Calcium channel blockers (CCBs) inhibit voltage-dependent L-type calcium channels. This leads to vascular smooth muscle relaxation and negative inotropic and chronotropic effects in the heart. The latter are counteracted in vivo by a vasodilatation-triggered, baroreceptor-mediated reflex increase in sympathetic tone, resulting in indirect cardiostimulation. The mean vascular/cardiac effect ratios of the first-generation CCBs-verapamil, nifedipine, and diltiazem-are relatively low and amount to approximately 3, 10, and 3, respectively. The pharmacokinetic properties of verapamil, nifedipine, and diltiazem are similar. The drugs are almost completely absorbed after oral administration, but their bioavailability is reduced because of first-pass hepatic metabolism. The onset of action of verapamil, nifedipine, and diltiazem, at least in immediate-release formulations, is relatively fast (0.5-2 hours), and their elimination half-lives range from 2 to 7 hours. The second-generation CCBs (e.g., amlodipine, felodipine, and nisoldipine) have a slower onset of action (due to either intrinsic properties of the drug or a slow-release formulation), a longer duration of action, and greater vascular/cardiac effect ratios. These features may provide therapeutic benefits, for example, a less pronounced increase in sympathetic tone and reflex tachycardia, and reduced likelihood of negative inotropic effects. These agents can therefore probably be used in patients with left ventricular dysfunction.

Dasatinib is a novel second-generation inhibitor of multiple tyrosine kinases, indicated for the treatment for Philadelphia chromosome-positive (Ph+) chronic myeloid leukaemia (CML), acute lymphoblastic leukaemia (ALL) and lymphoid blast CML with resistance or intolerance to prior therapy. Although dasatinib is a potent, efficacious and generally well-tolerated drug, patients are also subject to various adverse effects. The most common pulmonary-related side effect is pleural effusion (PE). Renal failure has been reported rarely as a side effect of dasatinib treatment. We report the first case of a patient with imatinib-resistant CML who developed PE and acute renal failure (ARF) simultaneously, after being placed on dasatinib therapy.

The aim of this study was to examine the effects of amlodipine (AML) in rat testicular torsion/detorsion damage. In this study, rats were divided into eight groups: (i) sham; (ii) testicular ischaemia, 2 h of ischaemia; (iii) testicular ischaemia/reperfusion (I/R), 2 h of ischaemia followed by 2 h of reperfusion; (iv) ischaemia + AML (5 mg kg(-1)) administered 30 min before ischaemia; (v) ischaemia + AML (10 mg kg(-1)) administered 30 min before ischaemia; (vi) and (vii) I/R + AML (5 mg kg(-1)) and I/R + AML (10 mg kg(-1)) administered 1.5 h after the induction of ischaemia, respectively, and at the end of a 2-h ischaemia period and a 2-h reperfusion period applied; and (viii) sham + AML (10 mg kg(-1)). Significant decreases in levels of superoxide dismutase and glutathione were observed in ischaemia and reperfusion groups when compared with healthy controls. These antioxidant levels increased in AML groups while malondialdehyde levels significantly decreased. While increases in tumour necrosis factor-alpha and transforming growth factor-beta levels were found in the torsion and detorsion groups, significant decreases in the levels of these inflammatory cytokines were observed in the treatment groups. These results demonstrate that AML significantly produced protective effects on testis tissue damage that occurs in the torsion/detorsion model via biochemical, histopathological and molecular pathways.

Biomarkers are being increasingly used in the study of cardiovascular disease because they provide readily quantifiable surrogate endpoints and allow accurate assessment of the effects of therapy on particular pathological processes. However, in order to be useful, biomarkers must be relevant, predictable, accurate, and reproducible. There is compelling evidence from large-scale clinical trials that inhibitors of the renin-angiotensin system [angiotensin-converting enzyme inhibitors and angiotensin type II receptor blockers (ARBs)] and calcium channel blockers (CCBs) may have beneficial effects beyond blood pressure control in the treatment of hypertension. Biomarkers are expected to provide further insight into these beneficial effects and allow for quantitative assessment. This review summarizes the published clinical evidence on the effects of various antihypertensive drugs, particularly ARBs (e.g. losartan and olmesartan medoxomil) and CCBs (e.g. amlodipine), alone and in combination with other agents (e.g. hydrochlorothiazide), on central aortic pressure and the biomarkers high-sensitivity C-reactive protein (hsCRP), adiponectin, cystatin C, homeostasis model assessment of insulin resistance (HOMA-IR), procollagen, tumor necrosis factor-α, and interleukin-6. Of these biomarkers, the benefits of antihypertensive therapy on hsCRP, adiponectin, and HOMA-IR reflect a potential for quantifiable long-term vascular benefits.

Matrix metalloproteinase-1 (MMP-1) may play an important role in the pathogenesis of atherosclerosis and atherosclerotic plaque rupture. We investigated the effect of the calcium channel blockers amlodipine and nifedipine on the expression of MMP-1 and tissue inhibitor of metalloproteinase-1 (TIMP-1) in endothelial cells (ECs). MMP-1 and TIMP-1 levels in conditioned media of human vascular ECs were measured by enzyme-linked immunosorbent assay. Collagenolytic activity was determined by fluorescence-labeled collagen digestion. The addition of interleukin-1beta (IL-1beta) increased MMP-1 levels in the culture media of ECs. Amlodipine, but not nifedipine, significantly decreased MMP-1 levels in IL-1beta-stimulated ECs. TIMP-1 levels also were significantly increased by IL-1beta, and its expression was slightly decreased by amlodipine, not by nifedipine. Amlodipine significantly inhibited collagenolytic activity in the culture media of IL-1beta-stimulated ECs, whereas nifedipine showed no significant effect on the activity. Our findings revealed that buy norvasc online amlodipine, but not nifedipine, inhibits IL-1beta-induced MMP-1 expression in human ECs.

A 35-year-old woman with a history of breast cancer, treated 3 years ago with surgery, radiation, and chemotherapy presented with a rapid onset of severe Raynaud's phenomenon. On physical examination, she had digital ulcers and splinter hemorrhages; there were no signs of an underlying rheumatic condition. Laboratory evaluation revealed anemia, the presence of antinuclear antibody and slight depression in her serum complement C3 level. The remainder of her serologic evaluation, including extractable nuclear antigens, anti-double-stranded DNA antibody, antiphospholipid antibodies, rheumatoid factor, anti-neutrophil cytoplasmic antibodies, cryoglobulins, and cold agglutins, were negative. Within weeks of her presentation, she developed acute renal failure and bilateral lower extremity edema. A computed tomography scan of her abdomen and pelvis showed bulky lymphadenopathy and hydronephrosis; a pelvic lymph node biopsy revealed metastatic breast cancer. She was initially managed with passive rewarming strategies, topical antibiotics, vasodilator and anti-platelet therapy, but had a negligible response. However, once she was buy norvasc online started on chemotherapy for her recurrent malignancy, there was a significant improvement in her Raynaud's symptoms and resolution of her digital ulcers.

Grapefruit juice can alter oral drug pharmacokinetics by different buy norvasc online mechanisms. Irreversible inactivation of intestinal cytochrome P450 (CYP) 3A4 is produced by commercial grapefruit juice given as a single normal amount (e.g. 200-300 mL) or by whole fresh fruit segments. As a result, presystemic metabolism is reduced and oral drug bioavailability increased. Enhanced oral drug bioavailability can occur 24 hours after juice consumption. Inhibition of P-glycoprotein (P-gp) is a possible mechanism that increases oral drug bioavailability by reducing intestinal and/or hepatic efflux transport. Recently, inhibition of organic anion transporting polypeptides by grapefruit juice was observed in vitro; intestinal uptake transport appeared decreased as oral drug bioavailability was reduced. Numerous medications used in the prevention or treatment of coronary artery disease and its complications have been observed or are predicted to interact with grapefruit juice. Such interactions may increase the risk of rhabdomyolysis when dyslipidemia is treated with the HMG-CoA reductase inhibitors atorvastatin, lovastatin, or simvastatin. Potential alternative agents are pravastatin, fluvastatin, or rosuvastatin. Such interactions might also cause excessive vasodilatation when hypertension is managed with the dihydropyridines felodipine, nicardipine, nifedipine, nisoldipine, or nitrendipine. An alternative agent could be amlodipine. In contrast, the therapeutic effect of the angiotensin II type 1 receptor antagonist losartan may be reduced by grapefruit juice. Grapefruit juice interacting with the antidiabetic agent repaglinide may cause hypoglycemia, and interaction with the appetite suppressant sibutramine may cause elevated BP and HR. In angina pectoris, administration of grapefruit juice could result in atrioventricular conduction disorders with verapamil or attenuated antiplatelet activity with clopidrogel. Grapefruit juice may enhance drug toxicity for antiarrhythmic agents such as amiodarone, quinidine, disopyramide, or propafenone, and for the congestive heart failure drug, carvediol. Some drugs for the treatment of peripheral or central vascular disease also have the potential to interact with grapefruit juice. Interaction with sildenafil, tadalafil, or vardenafil for erectile dysfunction, may cause serious systemic vasodilatation especially when combined with a nitrate. Interaction between ergotamine for migraine and grapefruit juice may cause gangrene or stroke. In stroke, interaction with nimodipine may cause systemic hypotension. If a drug has low inherent oral bioavailability from presystemic metabolism by CYP3A4 or efflux transport by P-gp and the potential to produce serious overdose toxicity, avoidance of grapefruit juice entirely during pharmacotherapy appears mandatory. Although altered drug response is variable among individuals, the outcome is difficult to predict and avoiding the combination will guarantee toxicity is prevented. The elderly are at particular risk, as they are often prescribed medications and frequently consume grapefruit juice.

Up to October 2011, 434 articles were identified. After full-text checking and quality assessment, 30 articles were finally included in this review involving 39 study settings. All 6 ACEIs studies were literature-based evaluations which synthesized data from different sources. Other 33 studies were directed at ARBs and were designed based on specific trials. The Markov buy norvasc online model was the most common decision analytic method used in the evaluations. From the cost-effectiveness results, 37 out of 39 studies indicated either ACEIs or ARBs were cost-saving comparing with placebo/conventional treatment, such as amlodipine. A lack of evidence was assessed for valid direct comparison of cost-effectiveness between ACEIs and ARBs.

Self-monitoring values of blood pressure may better reflect the average long-term blood pressure value than sporadic measurements in the physician's office and be more useful for blood pressure control. In buy norvasc online the present study, we compared the results of self-monitoring of blood pressure values, especially in the morning, with office blood pressure, and related these to progression of chronic renal insufficiency and left ventricular hypertrophy (LVH). Thirty-four patients were selected from 316 subjects with chronic renal insufficiency (average serum creatinine 1.72 +/- 0.15 mg/dl, mean age 52.6 +/- 3.5 yrs) in accordance with the following criteria (1) office blood pressure was less than 140/90 mmHg, (2) blood pressure was controlled with amlodipine (5-20 mg/day) combined with benazepril (2.5 mg/day), (3) morning blood pressure was greater than 150/90 mmHg at 6-9 AM and (4) LVH had been determined by echocardiography (posterior wall thickness; PWT > or = 12 mm). The patients were assigned to 2 groups at random and were given: (1) guanabenz (GB; 2-8 mg at I I PM, n = 17) or (2) placebo (n = 17). Two years later, the average blood pressure of both groups as measured in the office was not significantly different: however, BP in the morning was significantly reduced from 158 +/- 6 to 134 +/- 4 mmHg in GB treated group (P< 0.001). In 14 of 17 patients in GB treated group, LVH resolved and there was only mild progression of nephropathy (serum creatinine: 1.69 +/- 0.18 to 1.81 +/- 0.19 mg/dl). In 12 of 14 patients in placebo group, whose morning blood pressure remained at greater than 150/90 mmHg, LVH was retained and there was moderate progression of nephropathy (serum creatinine: 1.73 +/- 0.14 to 2.62 +/- 0.50mg/dl). From these results, it is suggested that antihypertensive treatment with combination therapy based on self-monitoring BP is cardio-renoprotective in patients with chronic renal insufficiency and LVH.

A simple, specific, accurate and precise stability-indicating reversed-phase high-performance liquid chromatographic method was developed for simultaneous estimation of olmesartan medoxomile (OLME), amlodipine besylate (AMLO) and hydrochlorothiazide (HCTZ) in tablet dosage form. The buy norvasc online method was developed using an RP C18 base deactivated silica column (250 × 4.6 mm, 5 µm) with a mobile phase consisting of triethylamine (pH 3.0) adjusted with orthophosphoric acid (A) and acetonitrile (B), with a timed gradient program of T/%B: 0/30, 7/70, 8/30, 10/30 with a flow rate of 1.4 mL/min. Ultraviolet detection was used at 236 nm. The retention times for OLME, AMLO and HCTZ were found to be 6.72, 4.28 and 2.30, respectively. The proposed method was validated for precision, accuracy, linearity, range, robustness, ruggedness and force degradation study. The calibration curves of OLME, AMLO and HCTZ were linear over the range of 50-150, 12.5-37.5 and 31-93 µg/mL, respectively. The method was found to be sensitive. The limits of detection of OLME, AMLO and HCTZ were determined 0.19, 0.16 and 0.22 µg/mL and limits of quantification of OLME, AMLO and HCTZ were determined 0.57, 0.49 and 0.66, respectively. Forced degradation study was performed according to International Conference on Harmonization guidelines.

The amlodipine-perindopril and atenolol-thiazide regimens had different effects on daytime and night-time ABP, which may have contributed to the lower rates of events in patients treated with amlodipine-perindopril therapy. Both CBP and ABP were significantly associated with rates of cardiovascular events. ABP nocturnal pressures provided complimentary and incremental utility over CBP in the prediction of cardiovascular risk in treated hypertensive patients. These data support the buy norvasc online use of ABP to assess the effect of antihypertensive treatment in clinical practice.

Calcium salts are frequently used in the treatment of calcium antagonist poisoning. Different dosing regimens have been employed. The major risk of high dose calcium therapy is iatrogenic hypercalcemia, especially in patients with diminished renal function. Repeated doses of calcium are therefore often avoided; however, inadequate use of intravenous calcium may cause treatment failure in severe calcium Retrovir 200 Mg antagonist overdose. We report our experience of using high dose intravenous calcium chloride effectively and safely to treat severe amlodipine overdose in a patient with severe renal insufficiency.

Candesartan Antihypertensive Survival Evaluation in Japan (CASE-J) trial was conducted to compare the effects of the angiotensin II receptor blocker (ARB) candesartan and the calcium channel blocker (CCB) amlodipine on the incidence of cardiovascular (CV) events in Japanese high-risk hypertensive patients. After 3.2years follow-up, CV events rate was 17.6-17.7 per 1000 person-years in each group, which was much lower than we expected. Since it has not been known whether the same efficacy of two drugs is sustained beyond the current trial, a longer follow-up period will be needed. The Steering Committee of CASE-J trial decided to extend the trial for 3years as an observational study (CASE-J Ex). In CASE-J Ex, the primary end point is a composite of CV events and the secondary endpoints are all-cause death and new-onset diabetes. After Committee's decision, 245 doctors agreed to participate in CASE-J Ex and 2236 patients (1141 with candesartan-based regimens and 1095 with amlodipine-based regimens) were re-enrolled. The baseline characteristics of CASE-J Ex participants were similar to CASE-J participants and still balanced well between candesartan and amlodipine. Recently, the interest of antihypertensive treatment has focused to differentiation of the effects of antihypertensive agents on the incidence of CV events as well as blood pressure lowering effect. CASE-J Ex will clarify the long-term effects of ARB and CCB on CV mortality and morbidity. Additionally, because the number of diabetic patients is increased, the evidences from CASE-J Ex will be valuable.

Background. Numbers of drugs are required to manage patients with chronic kidney disease (CKD). Drug adherence is relatively poor in this population. Methods. In 36 CKD patients with hypertension and dyslipidemia, who were prescribing amlodipine 5 mg and atorvastatin 10 mg daily, the influences of exchanging to a combination drug containing equivalent doses of amlodipine and atorvastatin were observed for 6 months. Results. At the baseline, flow-mediated dilation (FMD) was reduced (2.4 ± 0.3%), and proteinuria was significantly contributed to decrements of FMD (R (2) = 0.38, F = 3.7, df (6,29), and  P < 0.01). Six months later from exchanging to combination drug, total cholesterol (TC, 197 ± 5 to 183 ± 3 mg/dL,  P < 0.01) and triglycerides (142 ± 14 to 129 ± 10 mg/dL, P < 0.05) were decreased, but high density lipoprotein cholesterol (53 ± 3 to 56 ± 3 mg/dL, P < 0.05) was increased. FMD was slightly albeit significantly improved to 2.7 ± 0.3% (P < 0.05). No serious adverse effects were seen by the combination drug. Subanalysis for the patients with considerable reductions of TC demonstrated that the combination drug decreased proteinuria and high sensitive CRP (P < 0.05 for both). Conclusion. Our data indicate that proteinuria constitutes a determinant of a reduced FMD. The present results implicate that combination drug is useful to improve adherence and suggest that atorvastatin refines endothelium function as well as lipid profiles in CKD patients.
