The influence of ethacrynic acid, hydrochlorothiazide and clopamide on the renal excretion of chloramphenicol and its metabolites.
Simultaneous administration of chloramphenicol (1 g orally) and ethacrynic acid (150 mg orally), hydrochlorothiazide (25 mg orally) or clopamide (40 mg orally) increased the urinary excretion of chloramphenicol and its metabolites (aryl amines and total nitro compounds). The administration of diuretics did not change the time course of serum concentrations of substances under study. Since the urinary excretion of chloramphenicol and its metabolites is a urine flow-dependent process, the influence of the tested diuretics can be explained as a consequence of decreased tubular water reabsorption.
