1. The mechanism of the antidiuretic effect of hydrochlorothiazide in diabetes insipidus was studied in anaesthetized Brattleboro rats with the hereditary hypothalamic form of the disease. 2. The antidiuresis caused by acute administration of hydrochlorothiazide followed an increase in sodium excretion and was associated with a significant fall in the plasma sodium concentration. There were con...

The antihypertensive effect and safety of fosinopril and hydrochlorothiazide combined were compared with each drug singly and placebo in a controlled manner. After a 4- to 5-week placebo lead-in period, 67 mild to moderate essential hypertensive patients (seated diastolic blood pressure > or = 95 and < or = 110 mm Hg) were randomized in a double-blind fashion into four parallel treatment groups...

Thiazide and thiazide-like diuretics are widely used in the management of hypertension, but recently the equivalence of hydrochlorothiazide and chlorthalidone for blood pressure (BP) lowering and prevention of cardiovascular disease has been questioned. We performed a meta-analysis to characterize the dose-response relationships for 3 commonly prescribed thiazide diuretics, hydrochlorothiazide,...

Treatment of ischemic hypertensive patients with hydrochlorothiazide can precipitate cardiac arrhythmias. The present study was undertaken to evaluate the diuretic potential of green tea alone and its effects on hydrochlorothiazide in interactive groups. Rats were treated with high (500 mg/kg, p.o.) and low (100 mg/kg, p.o.) dose of green tea extract in alone and interactive groups for 30 days....

A procedure for simultaneous determination of metoprolol and hydrochlorothiazide in tablets by employing derivative spectrophotometry, "zero-crossing" method was developed. The third order derivative absorption spectra at lambda approximately 281 nm were used for metoprolol and the first order derivative spectra at lambda approximately 282 nm were used for hydrochlorothiazide. No interferences ...

We investigated serum glucose and insulin levels resulting from thiazide or thiazide-like diuretic administration and determined whether they were associated with serum or intracellular potassium or magnesium values. We also explored the role of obesity both alone and with thiazides on serum insulin and glucose. Hypertensive men were withdrawn from diuretics and repleted with oral potassium and...

A simple, reproducible and efficient reverse phase high performance liquid chromatographic method was developed for simultaneous determination of valsartan and hydrochlorothiazide in tablets. A column having 200 x 4.6 mm i.d. in isocratic mode with mobile phase containing methanol:acetonitrile:water:isopropylalcohol (22:18:68:2; adjusted to pH 8.0 using triethylamine; v/v) was used. The flow ra...

Myocardial infarction, generally known as ‘heart attack’ occurs predominantly during the early morning hours and a cause of millions death worldwide. Hydrochlorothiazide is recommended drug for prevention heart disease, but commercial market lacks its long action (>4 h) formulation. The endeavor present research was to develop quality product profile hydrochlorothiazide modified release tablets...

BACKGROUND The Avoiding Cardiovascular Events through Combination Therapy in Patients Living with Systolic Hypertension (ACCOMPLISH) trial showed that initial antihypertensive therapy with benazepril plus amlodipine was superior to benazepril plus hydrochlorothiazide in reducing cardiovascular morbidity and mortality. We assessed the effects of these drug combinations on progression of chronic ...
