Aldactazide Chemical Information

hydrochlorothiazide - The hydrogenated derivative of chlorothiazide, a thiazide diuretic with antihypertensive and anti-urolithic effects. This agent binds to the electroneutral Na-K-Cl cotransporter (NKCC) and thereby impairs Na+, K+ and Cl- reabsorption on the luminal membrane of the early segment in the distal convoluted tubule in the kidney. This leads to an increase in urinary excretion of sodium, chloride, potassium, bicarbonate and water subsequently reducing plasma and extracellular fluid volume leading to a reduction in blood pressure. Hydrochlorothiazide also decreases urinary calcium and uric acid excretion by direct action on the distal tubule.

spironolactone - A synthetic 17-spironolactone corticosteroid with potassium-sparing diuretic, antihypertensive, and antiandrogen activities. Spironolactone competitively inhibits adrenocortical hormone aldosterone activity in the distal renal tubules, myocardium, and vasculature. This agent may inhibit the pathophysiologic effects of aldosterone produced in excess by various types of malignant and benign tumors. (NCI04)
