title: Diuretic therapy in congestive heart failure.
abstract: Diuretics are a mainstay of therapy in patients with congestive heart failure. A small number of patients can achieve adequate diuresis with a thiazide diuretic alone, but most require a loop diuretic. Some patients with severe disease require combinations of diuretics. Most patients with congestive heart failure manifest resistance to diuretics by having a diminished natriuresis compared with healthy counterparts. This diminished response even to potent diuretics means that dietary sodium may exceed sodium excretion, resulting in patient decompensation. The pharmacokinetics and pharmacodynamics of loop diuretics have been characterized in patients with congestive heart failure, thereby allowing rational therapeutic strategies in terms of what type of doses should be administered, how often, and when to use diuretic combinations. The purpose of this review is to show how understanding pharmacokinetics and pharmacodynamics results in logical diuretic use. (c)2000 by CHF, Inc.
