For reducing cardiovascular events (CVEs), HCTZ is less effective than enalapril and amlodipine in randomized trials, and, in network analysis of trials, it is less effective than CTDN and HCTZ-amiloride. : CD004351. AMIL, amiloride; BC, Bowman’s capsule; CD, collecting duct; CTDN, chlorthalidone; DCT, distal convoluted tubule; INDAP, indapamide; LoH, loop of Henle; MR, mineralocorticoid receptor; PCT, proximal convoluted tubule; SPIR, spironolactone; TRIAM, triamterene. With the advent of chlorthiazide in 1958, thiazide diuretics quickly became a key component in the management of hypertension.
Department of Medicine and Pharmacology, Virginia Commonwealth University We found 9 trials studying the blood pressure-lowering ability of 5 different loop diuretics (furosemide, cicletanine, piretanide, indacrinone and etozolin) in 460 participants. The blood pressure-lowering effect was modest, with systolic pressure lowered by … AMIL, amiloride; BC, Bowman’s capsule; CD, collecting duct; CTDN, chlorthalidone; DCT, distal convoluted tubule; INDAP, indapamide; LoH, loop of Henle; MR, mineralocorticoid receptor; PCT, proximal convoluted tubule; SPIR, spironolactone; TRIAM, triamterene.
No. Systematic reviews have shown proven benefit of antihypertensive drug therapy in reducing cardiovascular morbidity and mortality but most of the evidence is in people 60 years of age and older.
Diuretics are a popular, heterogenous class of antihypertensives with several decades of clinical application.

It has been updated this year by a team in Canada, led by Vijaya Musini. Loop diuretics are less effective than thiazide-type drugs in reducing BP in the nonedematous patient as has been shown in a recent Cochrane analysis reporting the SBP/diastolic BP reduction of several loop diuretics in primary hypertension. All effects on electrolytes take place on the lumenal side of the epithelial cell, while SPIR leads to reduction in Na–K exchange on the interstitial side as well. MicroRNA-17: A Modulator of Interferon Regulatory Factor 9-Induced Phenotypic Switching in Vascular Smooth Muscle Cells EPLER also reduces proteinuria and has beneficial effects on endothelial function. All effects on electrolytes take place on the lumenal side of the epithelial cell, while SPIR leads to reduction in Na–K exchange on the interstitial side as well. However, their antihypertensive and beneficial effects can be thwarted in many circumstances, such as by concomitant administration of nonsteroidal anti-inflammatory agents as noted above. Nine trials are included. She, Jim Wright and Ken Bassett describe their findings in this podcast. MicroRNA-183 as a novel regulator protects against cardiomyocytes hypertrophy via targeting TIAM1
While guidelines often do not differentiate among specific diuretics, this review demonstrates that these distinctions are important for managing hypertension. Potassium-sparing diuretics are probably underutilized. For other thiazide drugs, the lowest doses studied lowered blood pressure maximally and higher doses did not lower it … For Permissions, please email: firstname.lastname@example.org New review . Fifty years of thiazide diuretic therapy for hypertensionVeterans Administration Cooperative Study Group on Antihypertensive AgentsEffects of treatment on morbidity in hypertension. Calcium channel blockers versus other classes of drugs for hypertension. Informed decisions. The inferiority of hydrochlorothiazide (HCTZ) to thiazide-like diuretics and to other antihypertensive classes of medications has been recently reviewed in some detail. From Roush HCTZ was less effective in preventing CVEs compared to enalapril in the ANBP2 trial, to amlodipine in the ACCOMPLISH trial, and to CTDN and HCTZ-amiloride in network analyses of trials ( In spite of these observations, in 2013 HCTZ was the 12th most commonly prescribed drug in the US with 50 million prescriptions (not including fixed-dose combinations), and it is paradoxical that there has never been a placebo-controlled trial testing HCTZ’s efficacy in reducing CVEs. All rights reserved. Effect of alcohol on blood pressure . The distribution of CTDN into red blood cells creates a reservoir leading to a 2- to 3-day duration of action. The mean blood pressure-lowering effect over the dose range 6.25 mg, 12.5 mg, 25 mg and 50 mg/day is 4/2 mmHg, 6/3 mmHg, 8/3 mmHg and 11/5 mmHg, respectively. An extended serum half-life of one or the other of these drugs is only as relevant as the achieved concentration remaining above the threshold for drug effect.
