Diuretics in the therapy of hypertension: current status.

Diuretics were the first effective oral agents for treating hypertension. They have proven to be safe and effective. Recently, they have been scrutinized as possibly being responsible for certain side effects that may increase risk for cardiovascular morbidity and mortality. A careful review of the literature suggests this class of agents warrants continued use as first-line therapy of hypertension, especially in certain demographic groups. However, monitoring of potential baleful effects and a general reduction in dosage are appropriate. Furthermore, selection of other (alternative) agents for monotherapy is advised in certain clinical circumstances.
