Description and Uses

Hydrochlorothiazide is one of the most widely used drugs of this series, and it is used for the same indications, as is chlorothiazide. Hydrochlorothiazide causes less inhibition of carbonic anhydrase, but causes 5–10 times more diuresis of sodium ions than chlorothiazide using the same dose.
