A BLOOD PRESSURE regulating system of interacting components that include RENIN; ANGIOTENSINOGEN; ANGIOTENSIN CONVERTING ENZYME; ANGIOTENSIN I; ANGIOTENSIN II; and angiotensinase. Renin, an enzyme produced in the kidney, acts on angiotensinogen, an alpha-2 globulin produced by the liver, forming ANGIOTENSIN I.

Irbesartan reduces QT dispersion in hypertensive individuals. (1/1416)

Angiotensin type 1 receptor antagonists have direct effects on the autonomic nervous system and myocardium. Because of this, we hypothesized that irbesartan would reduce QT dispersion to a greater degree than amlodipine, a highly selective vasodilator. To test this, we gathered electrocardiographic (ECG) data from a multinational, multicenter, randomized, double-blind parallel group study that compared the antihypertensive efficacy of irbesartan and amlodipine in elderly subjects with mild to moderate hypertension. Subjects were treated for 6 months with either drug. Hydrochlorothiazide and atenolol were added after 12 weeks if blood pressure (BP) remained uncontrolled. ECGs were obtained before randomization and at 6 months. A total of 188 subjects (118 with baseline ECGs) were randomized. We analyzed 104 subjects who had complete ECGs at baseline and after 6 months of treatment. Baseline characteristics between treatments were similar, apart from a slight imbalance in diastolic BP (irbesartan [n=53] versus amlodipine [n=51], 99.2 [SD 3. 6] versus 100.8 [3.8] mm Hg; P=0.03). There were no significant differences in BP normalization (diastolic BP <90 mm Hg) between treatments at 6 months (irbesartan versus amlodipine, 80% versus 88%; P=0.378). We found a significant reduction in QT indexes in the irbesartan group (QTc dispersion mean, -11.4 [34.5] milliseconds, P=0.02; QTc max, -12.8 [35.5] milliseconds, P=0.01), and QTc dispersion did not correlate with the change in BP. The reduction in QT indexes with amlodipine (QTc dispersion, -9.7 [35.4] milliseconds, P=0.06; QTc max, -8.6 [33.2] milliseconds, P=0.07) did not quite reach statistical significance, but there was a correlation between the change in QT indexes and changes in systolic BP. In conclusion, irbesartan improved QT dispersion, and this effect may be important in preventing sudden cardiac death in at-risk hypertensive subjects.  (+info)

Angiotensin receptor subtype 1 mediates angiotensin II enhancement of isoproterenol-induced cyclic AMP production in preglomerular microvascular smooth muscle cells. (2/1416)

In a previous study, we found that angiotensin (Ang) II enhances beta-adrenoceptor-induced cAMP production in cultured preglomerular microvascular smooth muscle cells (PMVSMCs) obtained from spontaneously hypertensive rats. The purpose of the present investigation was to identify the Ang receptor subtypes that mediate this effect. In our first study, we compared the ability of Ang II, Ang III, Ang (3-8), and Ang (1-7) to increase cAMP production in isoproterenol (1 microM)-treated PMVSMCs. Each peptide was tested at 0.1, 1, 10, 100, and 1000 nM. Both Ang II and Ang III increased intracellular (EC50s, 1 and 11 nM, respectively) and extracellular (EC50s, 2 and 14 nM, respectively) cAMP levels in a concentration-dependent fashion. In contrast, Ang (3-8) and Ang (1-7) did not enhance either intracellular or extracellular cAMP levels at any concentration tested. In our second study, we examined the ability of L 158809 [a selective Ang receptor subtype 1 (AT1) receptor antagonist] to inhibit Ang II (100 nM) and Ang III (100 nM) enhancement of isoproterenol (1 microM)-induced cAMP production in PMVSMCs. L 158809 (10 nM) abolished or nearly abolished (p <.001) Ang II and Ang III enhancement of isoproterenol-induced intracellular and extracellular cAMP levels. In contrast, PD 123319 (300 nM; a selective AT2 receptor antagonist) did not significantly alter Ang II enhancement of isoproterenol-induced intracellular or extracellular cAMP levels. We conclude that AT1 receptors, but not AT2, Ang (3-8), nor Ang (1-7) receptors mediate Ang II and Ang III enhancement of beta-adrenoceptor-induced cAMP production in cultured PMVSMCs.  (+info)

Blocking angiotensin II ameliorates proteinuria and glomerular lesions in progressive mesangioproliferative glomerulonephritis. (3/1416)

BACKGROUND: The renin-angiotensin system is thought to be involved in the progression of glomerulonephritis (GN) into end-stage renal failure (ESRF) because of the observed renoprotective effects of angiotensin-converting enzyme inhibitors (ACEIs). However, ACEIs have pharmacological effects other than ACE inhibition that may help lower blood pressure and preserve glomerular structure. We previously reported a new animal model of progressive glomerulosclerosis induced by a single intravenous injection of an anti-Thy-1 monoclonal antibody, MoAb 1-22-3, in uninephrectomized rats. Using this new model of progressive GN, we examined the hypothesis that ACEIs prevent the progression to ESRF by modulating the effects of angiotensin II (Ang II) on the production of transforming growth factor-beta (TGF-beta) and extracellular matrix components. METHODS: We studied the effect of an ACEI (cilazapril) and an Ang II type 1 receptor antagonist (candesartan) on the clinical features and morphological lesions in the rat model previously reported. After 10 weeks of treatment with equihypotensive doses of cilazapril, cilazapril plus Hoe 140 (a bradykinin receptor B2 antagonist), candesartan, and hydralazine, we examined systolic blood pressure, urinary protein excretion, creatinine clearance, the glomerulosclerosis index, and the tubulointerstitial lesion index. We performed a semiquantitative evaluation of glomerular immunostaining for TGF-beta and collagen types I and III by immunofluorescence study and of these cortical mRNA levels by Northern blot analysis. RESULTS: Untreated rats developed massive proteinuria, renal dysfunction, and severe glomerular and tubulointerstitial injury, whereas uninephrectomized control rats did not. There was a significant increase in the levels of glomerular protein and cortical mRNA for TGF-beta and collagen types I and III in untreated rats. Cilazapril and candesartan prevented massive proteinuria, increased creatinine clearance, and ameliorated glomerular and tubulointerstitial injury. These drugs also reduced levels of glomerular protein and cortical mRNA for TGF-beta and collagen types I and III. Hoe 140 failed to blunt the renoprotective effect of cilazapril. Hydralazine did not exhibit a renoprotective effect. CONCLUSION: These results indicate that ACEIs prevent the progression to ESRF by modulating the effects of Ang II via Ang II type 1 receptor on the production of TGF-beta and collagen types I and III, as well as on intrarenal hemodynamics, but not by either increasing bradykinin activity or reducing blood pressure in this rat model of mesangial proliferative GN.  (+info)

Addition of angiotensin II receptor blockade to maximal angiotensin-converting enzyme inhibition improves exercise capacity in patients with severe congestive heart failure. (4/1416)

BACKGROUND: Incomplete suppression of the renin-angiotensin system during long-term ACE inhibition may contribute to symptomatic deterioration in patients with severe congestive heart failure (CHF). Combined angiotensin II type I (AT1) receptor blockade and ACE inhibition more completely suppresses the activated renin-angiotensin system than either intervention alone in sodium-depleted normal individuals. Whether AT1 receptor blockade with losartan improves exercise capacity in patients with severe CHF already treated with ACE inhibitors is unknown. METHODS AND RESULTS: Thirty-three patients with severe CHF despite treatment with maximally recommended or tolerated doses of ACE inhibitors were randomized 1:1 to receive 50 mg/d losartan or placebo for 6 months in addition to standard therapy in a multicenter, double-blind trial. Peak aerobic capacity (V(O2)) during symptom-limited treadmill exercise and NYHA functional class were determined at baseline and after 3 and 6 months of double-blind therapy. Peak V(O2) at baseline and after 3 and 6 months were 13.5+/-0.6, 15.1+/-1.0, and 15.7+/-1.1 mL. kg-1. min-1, respectively, in patients receiving losartan and 14.1+/-0.6, 14.3+/-0.9, and 13.6+/-1.1 mL. kg-1. min-1, respectively, in patients receiving placebo (P<0.02 for treatment group-by-time interaction). Functional class improved by at least one NYHA class in 9 of 16 patients receiving losartan and 1 of 17 patients receiving placebo. CONCLUSIONS: Losartan enhances peak exercise capacity and alleviates symptoms in patients with CHF who are severely symptomatic despite treatment with maximally recommended or tolerated doses of ACE inhibitors.  (+info)

Angiotensin converting enzyme inhibitors and angiotensin receptor (AT1) antagonists: either or both for primary renal disease? (5/1416)

At the present time we cannot assume that the proven benefits of ACEI on renal disease will be reproduced by using AT1-ra. With potentially differing modes of activity of these drugs, they cannot be seen as interchangeable and ACEI should remain the drug of choice in patients with progressive renal disease unless they are not tolerated. It is possible that AT1-ra may offer additional advantages in some patients or that synergy exists between the two agents, but this view will remain entirely speculative unless proper trials are conducted. Despite the results of the ELITE study [22], the uncertainty regarding the use AT1-ra in cardiovascular disease mirrors that of renal disease. This issue is obviously of relevance to the nephrologist in view of the spectrum of cardiac disease that accompanies chronic renal failure, such as left ventricular hypertrophy and cardiac failure, which provide multiple indications for manipulation of RAS. Despite their renoprotective effect, previous studies on ACEI [3,4] have not shown an overall reduction in mortality and this issue needs to be addressed in addition to renoprotection in studies comparing AT1-ra and ACEI.  (+info)

Effects of AT1 receptor blockade after myocardial infarct on myocardial fibrosis, stiffness, and contractility. (6/1416)

Angiotensin II type 1 (AT1) receptor blockade attenuates myocardial fibrosis after myocardial infarction (MI). However, whether inhibition of fibrosis by AT1 receptor blockade influences myocardial stiffness and contractility is unknown. We measured left ventricular (LV) hemodynamics, papillary muscle function, and myocardial stiffness and fibrosis in rats randomized to losartan or placebo 1 day after MI and treated subsequently for 8 wk. Losartan decreased LV and right ventricular weights as well as mean aortic and LV systolic pressures in sham and MI rats. LV end-diastolic pressure increased after MI and was decreased with losartan. Maximal developed tension and peak rate of tension rise and decline were decreased in MI vs. sham rats. Interstitial fibrosis developed after MI and was prevented in losartan-treated MI rats. The development of abnormal myocardial stiffness after MI was prevented by losartan. After MI, AT1 receptor blockade prevents an abnormal increase in myocardial collagen content. This effect was associated with a normalization of passive myocardial stiffness.  (+info)

Resetting of exaggerated tubuloglomerular feedback activity in acutely volume-expanded young SHR. (7/1416)

One purpose of the present study was to evaluate the ability of 7-wk-old spontaneously hypertensive rats (SHR) to reset tubuloglomerular feedback (TGF) activity in response to acute volume expansion (VE). Second, we evaluated the contribution of ANG II, via its action on AT1 receptors, to TGF control of glomerular function during VE. TGF was assessed by micropuncture methods and proximal tubular stop-flow pressure (SFP) determinations in SHR, Wistar-Kyoto rats (WKY), and Sprague-Dawley rats (SD). During euvolemia SHR exhibited enhanced TGF activity. In the same animals acute VE was achieved by infusion of saline (5 ml. h-1. 100 g body wt-1). VE led to resetting of TGF in all three strains. Maximal SFP responses, elicited by a 30-40 nl/min loop of Henle perfusion rate, decreased from 19 to 12 mmHg in SHR and, on average, from 11 to 5 mmHg in WKY and SD (P < 0.001). Tubular flow rate producing a half-maximal response (turning point) shifted to higher flow rates during VE, from 12 to 14 nl/min in SHR and from 15 to 19 nl/min in WKY. Administration of the AT1 receptor blocker candesartan (0.05 mg/kg iv) during sustained VE decreased TGF-mediated reductions in SFP in SHR and slightly increased the turning point in WKY. Nevertheless, other parameters of TGF activity were unaffected by AT1 receptor blockade. In conclusion, young SHR possess the ability to reset TGF activity in response to VE to a degree similar to compensatory adjustments in WKY. However, TGF remains enhanced in SHR during VE. ANG II and its action on AT1 receptors are in part responsible for the exaggerated SFP responses in young SHR during VE.  (+info)

Renal and hemodynamic effects of losartan in conscious dogs during controlled mechanical ventilation. (8/1416)

In 12 conscious dogs, we investigated whether the angiotensin II-receptor antagonist losartan increases renal sodium excretion and urine volume during controlled mechanical ventilation (CMV) with positive end-expiratory pressure. In four experimental protocols, the dogs were extracellular volume (ECV) expanded (electrolyte solution, 0.5 ml. kg-1. min-1 iv) or not and received losartan (100 micrograms. kg-1. min-1 iv) or not. They breathed spontaneously during the 1st and 4th hour and received CMV with positive end-expiratory pressure (mean airway pressure 20 cmH2O) during the 2nd and 3rd hours. In the expansion group, dogs with losartan excreted approximately 18% more sodium (69 +/- 7 vs. 38 +/- 5 micromol. min-1. kg-1) and 15% more urine during the 2 h of CMV because of a higher glomerular filtration rate (5.3 +/- 0.3 vs. 4.5 +/- 0.2 ml. min-1. kg-1) and the tubular effects of losartan. In the group without expansion, sodium excretion (2.0 +/- 0.6 vs. 2.6 +/- 1.0 micromol. min-1. kg-1) and glomerular filtration rate (3.8 +/- 0.3 vs. 3.8 +/- 0.4 ml. min-1. kg-1) did not change, and urine volume decreased similarly in both groups during CMV. Plasma vasopressin and aldosterone increased in both groups, and plasma renin activity increased from 4.9 +/- 0.7 to 7.8 +/- 1.3 ng ANG I. ml-1. h-1 during CMV in nonexpanded dogs without losartan. Mean arterial pressure decreased by 10 mmHg in nonexpanded dogs with losartan. In conclusion, losartan increases sodium excretion and urine volume during CMV if the ECV is expanded. If the ECV is not expanded, a decrease in mean arterial blood pressure and/or an increase in aldosterone and vasopressin during CMV attenuates the renal effects of losartan.  (+info)

INTRODUCTION: High spontaneous activity of the renin-angiotensin system (RAS) results in more pronounced cognitive impairment and more prolonged QTc interval during hypoglycaemia in type 1 diabetes. We tested whether angiotensin II receptor blockade improves cerebral and cardiovascular function during hypoglycaemia.. METHODS: Nine patients with type 1 diabetes and high spontaneous RAS activity were included in a double-blind, randomised, cross-over study on the effect of angiotensin II receptor antagonist (candesartan 32 mg) or placebo for one week on cognitive function, cardiovascular parameters, hormonal counter-regulatory response, substrate mobilisation, and symptoms during hypoglycaemia induced by two hyperinsulinaemic, hypoglycaemic clamps.. RESULTS: Compared to placebo, candesartan did neither change performance of the cognitive tests nor the EEG at a plasma glucose concentration of 2.6±0.2 mmol/l. During candesartan treatment, the QT interval in the ECG was not affected. No effect of ...
The meta-analysis by Etminan and colleagues addresses an interesting question. Do angiotensin II receptor antagonists, similar to β-blockers, calcium channel blockers, and angiotensin-converting enzyme inhibitors (1, 2), reduce the frequency of headaches in patients with hypertension? The pooled results show a reduction in headache frequency with angiotensin II receptor antagonists. The findings should be interpreted with caution, however, because headache was not the primary outcome in any of the individual studies; the angiotensin II receptor antagonists chosen were not standardized; doses were not equivalent; and the definitions and types of headaches were not specified. Did the patients in these studies have tension headaches, migraine headaches, nasosinus headaches, or cluster headaches? Meta-analysis of secondary study endpoints should be considered hypothesis-generating, and the authors rightly call for a clinical trial to confirm the findings of this meta-analysis. The mechanism of ...

Table of Contents: Angiotensin receptor antagonists were developed during the 1970th and 80th. In Germany there are seven labeled substances: losartan, valsartan, eprosartan, irbesartan, candesartan, telmisartan, olmesartan. They are all used for hypertension, some have additional indications like diabetic nephropathy or heart failure. In Europe there is no registration for children and adolescents younger than 18 years. In USA losartan and valsartan are labeled for children 6 years and older with primary hypertension. The most important clinical effects of the angiotensin receptor antagonists are lowering of systolic and diastolic blood pressure, antiproteinuric effects and amelioration of left ventricular hypertrophy. This article explores the efficacy and safety of angiotensin receptor antagonists in children and adolescents by means of a systematic review according to the standards of the Cochrane Collaboration. Beyond that a registry for children and adolescents with renal diseases in ...
36 Consistent with this hypothesis it appears that the beneficial effects of AT2R activation are more pronounced in the FVB/N strain, whereas the C57BL/6 strain seems to be associated with more deleterious effects of AT2R activation. 3). In this context it is important to note that ATBP - also known as ATIP and MTSG, since it was cloned independently by three different groups - mediates antiproliferative effects. 9,46 Interestingly, a high level of PLZF expression was especially observed in the heart by Northern blotting,5 which, considering that PLZF might be regulated depending on the genetic background and the (patho)physiological state, could explain the discrepancies in AT2R function observed in this organ.

INTRODUCTION: The evaluation of a new drug in normotensive volunteers provides important pharmacodynamic and pharmacokinetic information as long as the compound has a specific mechanism of action which can be evaluated in healthy subjects as well as in patients. The purpose of the present paper is to discuss the results that have been obtained in normal volunteers with the specific angiotensin II receptor antagonist, losartan potassium. DOSE-FINDING: Over the last few years, studies in normotensive subjects have demonstrated that the minimal dose of losartan that produces maximal efficacy is 40-80 mg. Losartan has a long duration of action and its ability to produce a sustained blockade of the renin-angiotensin system is due almost exclusively to the active metabolite E3174. HORMONAL EFFECTS: Angiotensin II receptor blockade with losartan induces an expected increase in plasma renin activity and plasma angiotensin II levels. A decrease in plasma aldosterone levels has been found only w
This study is a multicenter placebo-controlled double-blind randomized clinical trial. The design scheme is depicted in Figure 1. (see below). At the time of screening, all pentoxifylline-naïve participants must have been receiving angiotensin receptor blockers(ARB) per day for no less than 8 weeks and have stable renal function with serum creatinine elevation , 25% in the preceding 8 weeks. For patients taking maximal dose of angiotensin receptor blockers(ARB) for more than 8 weeks, randomization will be started after recruitment. For patients taking submaximal, fixed dose of angiotensin receptor blockers(ARB)for ≥ 8 weeks, with good BP(blood pressure), i.e., ≤ 130/80 mmHg, randomization can also be started after recruitment. However, for patients taking submaximal dose of angiotensin receptor blockers(ARB) with suboptimal BP, i.e., ?130/80 mmHg, patients can be recruited but will not be randomized until the dose of angiotensin receptor blockers(ARB) has been fixed for ≥ 8 weeks, or a ...

BACKGROUND: Few studies have directly compared the renoprotective effects of angiotensin II-receptor blockers and angiotensin-converting-enzyme (ACE) inhibitors in persons with type 2 diabetes. METHODS: In this prospective, multicenter, double-blind, five-year study, we randomly assigned 250 subjects with type 2 diabetes and early nephropathy to receive either the angiotensin II-receptor blocker telmisartan (80 mg daily, in 120 subjects) or the ACE inhibitor enalapril (20 mg daily, in 130 subjects). The primary end point was the change in the glomerular filtration rate (determined by measuring the plasma clearance of iohexol) between the baseline value and the last available value during the five-year treatment period. Secondary end points included the annual changes in the glomerular filtration rate, serum creatinine level, urinary albumin excretion, and blood pressure, the rates of end-stage renal disease and cardiovascular events, and the rate of death from all causes. RESULTS: After five ...

In this systematic review, we identified a significantly increased risk of hyperkalaemia among people prescribed aliskiren (Rasilez; Novartis Pharmaceuticals, Switzerland) in combination with an ACE inhibitor or angiotensin receptor blocker compared with those prescribed monotherapy using aliskiren, an ACE inhibitor, or angiotensin receptor blocker. This risk was about 50% greater in those prescribed combination therapy than among those receiving ACE inhibitors or angiotensin receptor blocker monotherapy, and was about 70% greater in those prescribed combination therapy than among those receiving aliskiren monotherapy. We found no evidence of a significant difference in the risk of acute kidney injury between the study groups.. To date, no published systematic reviews or meta-analyses have evaluated the safety of combination therapy with aliskiren and ACE inhibitors or angiotensin receptor blockers. Previously published pooled analyses of the safety of aliskiren have provided discordant ...

Primary Hypothesis:. To evaluate the combination of an angiotensin converting enzyme inhibitor (ACEI) with an angiotensin receptor blocker (ARB) vs. standard treatment with angiotensin receptor blocker on the progression of kidney disease in individuals with Type 2 diabetes and overt nephropathy.. The primary outcome is a composite endpoint of reduction in estimated GFR of 30 ml/min/1.73m*m in individuals with an estimated baseline GFR greater than or equal to 60 ml/min/1.73m*m; reduction in estimated GFR of greater than 50% in individuals with an estimated baseline GFR less than 60 mL/min/1.73m*m; progression to end-stage renal disease (defined as need for dialysis, renal transplant or an eGFR less than 15 ml/min/1.73m*m) or death.. Secondary outcome: a renal composite endpoint, defined as; reduction in estimated GFR of more than 50% (for individuals with a baseline estimated GFR less than 60 ml/min/1.73m*m); reduction in estimated GFR of more than 30 ml/min/1.73m*m (for individuals with a ...
The early blood pressure and hemodynamic effects of the converting enzyme inhibitor (CEI), captopril, were compared in 23 hypertensive patients with those of a specific angiotensin II antagonist (AA), [Sar1, Thr8] A II. AA reduced mean arterial pressure (MAP) greater than 10 mm Hg only in seven of 23 patients vs 15 of 23 who responded to CEI (p less than 0.02). With both drugs, changes in MAP were not associated with significant changes in cardiac output (p greater than 0.10 for both drugs), but correlated with changes in systemic resistance (TPR); r = 0.84, p less than 0.001 for AA and r = 0.71, p less than 0.001 for CEI. Changes in TPR and MAP correlated significantly and inversely with log plasma renin activity in both instances; for AA, r = 0.829 and for CEI, r = -0.737; p less than 0.001 for both. The slopes of the two regression lines were not significantly different but the intercepts were +8.47 mm Hg for AA vs -10.17 mm Hg for CEI (p less than 0.001). This quantitative difference in ...

Recent studies have revealed significant contributory functions of RAS in the pathophysiology of AD. Activation of RAS in the AD brain was reported by some groups.9-11 These findings support the attractive hypothesis that inhibition of the brain RAS could be a new therapeutic strategy for AD.12 Indeed, a recent study showed that treatment with brain-penetrating ACE inhibitors slowed the rate of cognitive decline in AD patients in comparison with other antihypertensive medication.21 However, some in vitro studies have suggested that ACE could play an important role in the metabolism of Aβ,22,23 demonstrating that ACE degraded Aβ and ACE inhibition increased Aβ levels. On the other hand, as treatment of Tg2576 mice with an ACE inhibitor promoted Aβ deposition,24 treatment with ACE inhibitors might be a risk factor for AD. This effect of ACE inhibition on Aβ metabolism should be carefully considered, especially in relation to long-term treatment with ACE inhibitors. Additional studies are ...

Posts about Angiotensin-receptor blockade and risk of cancer: meta-analysis of randomised controlled trials written by CWRUmedicine
The Food and Drugs Administration has completed a safety review of angiotensin receptor blockers (ARBs) after they were linked with an increased risk of cancer.. This review of 31 randomised clinical trials involving almost 156,000 participants, of whom 84,461 were treated with an ARB, found no increased risk. The review analysed the data for new cancer cases, cancer-related death, breast cancer, lung cancer and prostate cancer. There was no increase in risk for any of these outcomes.. Action: Clinicians and patients can be reassured by this safety review. It is important to note that the overall evidence still places ARBs are still second line to angiotensin converting enzyme inhibitors (ACEIs). ...

AU - Teachey, Mary K.. AU - Krekler, Michael. N1 - Copyright: Copyright 2017 Elsevier B.V., All rights reserved.. PY - 2001. Y1 - 2001. N2 - Effects of oral administration of the angiotensin II receptor antagonist (selective AT1-subtype) irbesartan on glucose tolerance and insulin action on skeletal-muscle glucose transport were assessed in the insulin-resistant obese Zucker rat. In the acute study, obese rats received either vehicle (water) or irbesartan 1 hour before the experiment. Although irbesartan had no effect on glucose transport (2-deoxyglucose uptake) in the epitrochlearis muscle, which consists mainly of type IIb fibers, acute angiotensin II receptor antagonism led to a dose-dependent increase in insulin action in the predominantly type I soleus muscle. Irbesartan at 25 and 50 mg/kg induced significant ...
The role of angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) reducing risk of cardiovascular events (CVEs) and preserving kidney function in patients with chronic kidney disease is well-documented. However, the efficacy and safety of these agents in dialysis patients is still a controversial issue. We systematically searched MEDLINE, Embase, Cochrane Library and Wanfang for randomized trials. The relative risk (RR) reductions were calculated with a random-effects model. Major cardiovascular events, changes in GFR and drug-related adverse events were analyzed. Eleven trials included 1856 participants who were receiving dialysis therapy. Compared with placebo or other active agents groups, ARB therapy reduced the risk of heart failure events by 33% (RR 0.67, 95% CI 0.47 to 0.93) with similar decrement in blood pressure in dialysis patients. Indirect comparison suggested that fewer cardiovascular events happened during treatment with ARB (0.77, 0.63 to 0.94). The

N2 - Angiotensin converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) are recommended for secondary prevention in peripheral artery disease, but their effectiveness in patients with critical limb ischemia (CLI) is uncertain. We reviewed 464 patients with CLI who underwent diagnostic angiography or endovascular intervention from 2006-2013 at a multidisciplinary vascular center. ACEI or ARB use was assessed at the time of angiography. Major adverse cardiovascular events (MACE), mortality, and major adverse limb events (MALE) were assessed during three-year follow-up. Propensity weighting was used to adjust for baseline differences between ...
Angiotensin-II receptor antagonists (or blockers) are a newer class of antihypertensive agents. These drugs are selective for angiotensin II (type 1 receptor); unlike angiotensin-converting enzyme inhibitors, they do not inhibit bradykinin metabolism or enhance prostaglandin synthesis. Angiotensin-II receptor antagonists are well tolerated. Cough occurs much less often with these agents than with angiotensin-converting enzyme inhibitors, and they do not adversely affect lipid profiles or cause rebound hypertension after discontinuation. Clinical trials indicate that angiotensin-II receptor antagonists are effective and safe in the treatment of hypertension. Their use in congestive heart failure and renal disease is under investigation.

METHODS: This study used the UK Clinical Practice Research Datalink, linking with the Hospital Episode Statistics (April 2006 to March 2012). Adults with hypertension (n = 470) were followed from the first ARB prescription date to the switching date (preswitching period); then from the switching date to the date when study ended, patient left the dataset or died (postswitching period). Patients were divided into ACEIs-combined (n = 369) and ACEIs-monotherapy (n = 101) groups by whether additional antihypertensive drugs were prescribed ...
Background; Angiotensin receptor blocker (ARB) is being extensively used to control hypertension. But, there have been limited data whether ARB is associated with increased incidence of new-onset diabetes mellitus (DM) or impaired glucose intolerance (IGT).. Methods; We investigated total 13,561 patients (pts) that was glycerate hemoglobin level , 6.0% and fasting glucose level , 124 mg/dL (ARB therapy group=3421 and control group=9808) from January 2004 to February 2012. To adjust potential confounders, a propensity score matched analysis was performed using the logistic regression model. The primary end-point was the cumulative incidence of new-onset DM, IGT, and impaired fasting glucose (IFG). Also, multivariable cox-regression analysis by adjusted by aforementioned variables was performed to determine the impact of statin therapy on the incidence of new-onset DM, IGT, and IFG.. Results; Mean follow-up duration was 534±604 days in all-pt group, and 608±607 days in propensity score matching ...

Quantitative autoradiography was used to characterize angiotensin AT1 and AT2 receptors, in the rat aorta at three developmental ages; embryonic day 18 (E18), and postnatal weeks 2 and 8. The expression of angiotensin receptors was higher in the aorta of E18 and 2-week-old rat. A major proportion of the angiotensin receptors expressed in the aorta at these two ages was AT2 (84 and 81% respectively). Conversely, in the aorta of 8-week-old rats, AT1 was the predominant angiotensin receptor subtype (71%). In 8-week-old rats, the AT2 subtype was also present (28%). In pre- and postnatal rats, [125I]Sar1-angiotensin II binding to AT1 receptors was sensitive to GTP gamma S whereas binding to AT2 receptors was not. AT2 receptors may serve an important role during stages of rapid growth of the aorta, and also have a significant function in the adult vasculature ...
2017 The Author. Published by Oxford University Press for the Infectious Diseases Society of America. Background. Although statins, angiotensin-converting enzyme inhibitors (ACEI) or angiotensin receptor blockers (ARB) are generally well tolerated, the impact of these therapies individually or in combination on the change in neurocognitive function in persons with human immunodeficiency virus infection is unknown. Methods. The study included participants in the AIDS Clinical Trials Group Longitudinal Linked Randomized Trials cohort participants not receiving a statin or ACEI/ARB within 30 days of first neurologic assessment (baseline), with assessments by NPZ-3 (z score of averaged Trailmaking A and B tests and digit symbol test [DST]) from ≥2 measurements. Marginal structural models estimated the causal effect of statin or ACEI/ARB initiation on neurocognitive function; initial constant slope was assumed during the first year of treatment and a second constant slope thereafter. Results. Of ...
Both angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) reduce angiotensin action. Angiotensin, a powerful hormone, has many actions, the most important of which is constriction of small blood vessels, leading to a rise in blood pressure and therefore in the pressure of blood within the glomerular capillaries in the kidneys. Lowering this pressure may well be the mechanism by which these drugs tend to slow progression of kidney failure.. The effects of ACEIs differ from those of ARBs in several important respects. It is even conceivable that taking drugs from both classes is more effective than taking just one or the other alone. Unfortunately, side-to-side comparisons of these two classes of drugs have not been performed, because the drug industry has no interest in such trials. These drugs are also effective in reducing urinary protein excretion in the nephrotic syndrome, and they also slow progression of chronic renal failure even when added to a ...

Perhaps the greatest limitation of current pain management is that the tools we have on hand are primarily palliative. While chronic pain can be ameliorated temporarily by interfering with nociceptor signaling pathways or by altering central affective processing, pharmacotherapy has little to offer when it comes to addressing underlying biological processes that lead to the establishment of chronic pain.. That may be about to change. The successful conclusion of the phase 2 clinical trial of the angiotensin II receptor type 2 (AT2) antagonist EMA401 serves as the vanguard for development of a promising new class of analgesics. The study by Rice et al. on behalf of Spinifex Pharmaceuticals shows convincingly that long-term treatment with an AT2 blocker is at least as effective as conventional therapies in ameliorating symptoms of post-herpetic neuralgia. EMA401 also appeared to be free of major side effects, perhaps in part because it does not accumulate in the CNS and therefore presumably ...

Angiotensin receptor blockers for the reduction of proteinuria in diabetic patients with overt nephropathy: results from the AMADEO study Prasad Bichu1, Ravi Nistala1, Asma Khan2, James R Sowers2, Adam Whaley-Connell11Divisions of Nephrology and Endocrinology; 2Department of Internal Medicine, University of Missouri-Columbia School of Medicine, Columbia Missouri, USAAbstract: Diabetic kidney disease is characterized by persistent albuminuria (>300 mg/dl or >200 μg/min) that is confirmed on at least 2 occasions 3 to 6 months apart, with a progressive decline in the glomerular filtration rate (GFR), elevated arterial blood pressure, and an increased risk for cardiovascular morbidity and mortality. Diabetic kidney disease is the leading cause of end stage renal disease (ESRD) prompting investigators to evaluate mechanisms by which to slow disease progression. One such mechanism is to block the activity of angiotensin II at the receptor site and agents that follow this mechanism are referred to as

Losartan is a 4-chloro-5-hydroxymethylimidazole derivative that is a potent and highly selective angiotensin II receptor antagonist. Losartan is metabolized in vivo in rats, monkeys, and humans to a carboxylic acid derivative E3174 that is pharmacologically more active than the parent compound. We have investigated the mechanism of this biotransformation in human liver preparations. The oxidation of both losartan and the putative aldehyde intermediate E3179 was catalyzed by the microsomal fraction, required both NADPH and molecular oxygen, and was inhibited by SKF 525-A, implicating cytochrome P450 (CYP). When incubations with each substrate were performed under an atmosphere of 18O2, the extent of 18O incorporation into the carboxylic acid product was consistent with a mechanism for losartan oxidation involving an aldehyde intermediate. To substantiate the involvement of CYP in these reactions, incubations with losartan and the aldehyde E3179 were performed in the presence of isoform-selective ...
TY - JOUR. T1 - Angiotensin receptor blockers. T2 - Clinical relevance and new opportunities. AU - Volpe, Massimo. PY - 2012. Y1 - 2012. N2 - Effective treatment of high blood pressure (BP) is a key strategy for reducing the burden of hypertension-related cardiovascular diseases, ie, mainly stroke, myocardial infarction, heart failure, and cardiovascular death. Despite these well-established concepts, however, hypertension remains poorly controlled worldwide. In addition, patients treated for hypertension often remain at a higher risk as compared to the normotensive population, even when a satisfactory BP control is achieved. This is due to the concomitant presence of metabolic abnormalities and/or organ damage, thus accounting for the high or very high added cardiovascular risk profile often observed in patients with hypertension. An emerging strategy to improve general BP control and achieve this unmet target for cardiovascular disease prevention in patients with hypertension is represented by ...
It is well-known that cardiac hypertrophy and arterial and renal dysfunction are serious complications of hypertension. Therefore, we investigated the chronic effects of 606A (2-propyl-3-[2′(1,I,H,/I,-tetrazole-5-yl)biphenyl-4-yl]methyl-5-acetyl-4, 5, 6, 7-tetrahydro imidazo[4, 5-,I,c,/I,]pyridine-4-carboxylic acid disodium salt), a novel AT,SUB,1,/SUB,-receptor antagonist, on these complications of hypertension in stroke-prone spontaneously hypertensive rats (SHRSP) using Wistar Kyoto rats (WKY) as the control. After 8 weeks treatment from 16 weeks of age with 606A by a subcutaneously implanted osmotic pump, cardiac function, cardiac weight, acetylcholine-induced endothelium-dependent relaxation in the isolated aorta and renal function were estimated. Furthermore, wall thickness of the left ventricle was studied morphologically. We found that 606A (0.3 mg, 1 mg and 3 mg/head/day) dose-dependently lowered blood pressure without any effects on heart rate in SHRSP. Long-term treatments with 606A ...
Renin-angiotensin system inhibitors, specifically angiotensin II converting enzyme inhibitors (ACEI) and angiotensin II receptor blockers (ARB), have confirmed renoprotective benefits in patients with proteinuria and hypertension. However, it remains controversial whether these agents are beneficial to kidney recipients. We conducted this meta-analysis to evaluate the effects of ACEI/ARB treatment on patient and allograft survival after kidney transplant. The PubMed, Embase and Cochrane Library databases were searched for eligible articles from before May 2016, and we included 24 articles (9 randomised controlled trials [RCTs] and 15 cohort studies with 54,096 patients), in which patient or graft survival was compared between an ACEI/ARB treatment arm and a control arm ...

Patients with type 2 diabetes frequently have to be treated with more than one drug. Effects of oral antidiabetic drugs depend on the extent of drug absorption from the gut lumen, on metabolism of the drug in the liver, and on the extent of its excretion into bile and urine (21). In general, modification of all these processes by a second, concomitantly administered drug can alter the effects of oral antidiabetic drugs (21).. Recently, it was recognized that a broad variety of drugs, including many cardiovascular drugs such as statins and angiotensin II-receptor antagonists, is transported through biological membranes via specific transport proteins (15,22-24). For example, the efflux transporter P-glycoprotein, which translocates its substrates from the inside of the cell to the outside (e.g., from the hepatocyte into bile) is a major determinant of drug effects (1). If P-glycoprotein-mediated drug excretion is inhibited by a second, concomitantly administered compound, drug plasma ...
Abstract:. Candesartan is potent antihypertensive drug of class angiotensin II receptor antagonist. But it exhibits poor water solubility and extensive first pass metabolism. Present research deals with development of candesartan buccal film. Optimisation of buccal film was done by design expert. Optimised concentration range selected for development of trial batches of candesaratanbuccal films. Mucoadhesivebuccal films of candesartan were prepared by solvent casting technique using chitosan, HPMC, gelatin and EDTA as permeation enhancer. Prepared buccal films evaluated for various pharmaceutical parameters, stability studies, in-vitro and ex-vivo evaluation parameters performed. In-vitroangiotensin II receptor antagonist studies were also performed. Results showed improved bioavaibility of candesartan through buccal films.. ...
Angiotensin II receptor blockers, also known as ARB blockers or angiotensin 2 receptor blockers, are drugs used to treat high blood pressure and heart failure. They do not interfere with the bodys production of angiotensin. Instead, they block the effects of angiotensin, preventing the hormone from narrowing the blood vessels. By relaxing the coronary arteries, blood flow to the heart increases, blood pressure goes down and the hearts workload is reduced. Angiotensin II receptor blockers are often used in patients who cannot tolerate a common type of drugs known as ACE inhibitors.. ...

Supplementary Materials Supplemental file 1 IAI. IL-12 creation in neutrophils, accompanied by IRF-1 and AP-1 gene expression. Bacteria in which the exported repetitive protein (Erp)-like gene was deleted ([2,C5], get away from phagosomes by [2, 6, 7] and [2, 8, 9], and reprogramming of phagosome maturation by [2, 10,C12]). Such bacterial persistence can result in chronic, latent, or low-grade attacks in the sponsor (13,C15). A number of chemical agents have already been developed to take care of persistent bacterial attacks in mammals. In the entire case of LY2801653 (Merestinib) bacterial attacks recalcitrant to chemical substance treatment, however, vaccines are used like a preventive measure often. Live-attenuated vaccines, like the bacillus Calmette-Gurin (BCG) vaccine, work against these diseases often. In some full cases, authorized inactivated vaccines show poor effectiveness (16, 17) because they dont induce solid cell-mediated immunity (CMI), which straight kills contaminated cells ...
The guidelines above are for the general population, but seniors health needs and benchmarks differ from those of younger individuals in many ways. While 130/80 mmHg is the generic threshold for beginning BP medications, there have been many disagreements among medical professionals regarding the threshold for older adults. Age, frailty and other comorbidities like diabetes and chronic kidney disease complicate this matter even further.. The Eighth Joint National Committee (JNC 8) issued guidelines in 2013 recommending that individuals over age 60 aim for a reading below 150/90 mmHg. The JNC 8 recommendation for patients of any age with diabetes or chronic kidney disease is to aim for BP readings below 140/90 mmHg. These are not hard and fast rules, though, because each seniors health needs are unique.. The JNC 8 guidelines support what we geriatricians have believed for quite some time: many older adults are taking too much BP medication, says Dr. Leslie Kernisan, M.D., M.P.H. In addition ...

Results We identified 100 043 patients with a first-time stroke. Of these, 83 736 patients had ischaemic stroke, 11 779 had ICH, and 4528 had SAH. For ischaemic stroke, the adjusted 30-day MRR was reduced in current users compared with non-users (0.85, 95% CI 0.81 to 0.89). There was no reduction in the adjusted 30-day MRR for ICH (0.95, 95% CI 0.87 to 1.03) or SAH (1.01, 95% CI 0.84 to 1.21), comparing current users with non-users. No association with mortality was found among former users compared with non-users. No notable modification of the association was observed within sex or age strata. ...

Patients with underlying cardiovascular diseases appear to have an increased risk for adverse outcomes with coronavirus disease 2019 (COVID-19). Although the clinical manifestations of COVID-19 are dominated by respiratory symptoms, some patients also may have severe cardiovascular damage. Angiotensin converting enzyme 2 (ACE2) receptors have been shown to be the entry point into human cells for SARS-CoV-2, the virus that causes COVID-19. In a few experimental studies with animal models, both angiotensin converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) have been shown to upregulate ACE2 expression in the heart. Though these have not been shown in human studies, or in the setting of COVID-19, such potential upregulation of ACE2 by ACE inhibitors or ARBs has resulted in a speculation of potential increased risk for COVID-19 infection in patients with background treatment of these medications.. ACE2 is a homolog of angiotensin converting enzyme (ACE). ACE2 negatively ...
