DIURIL (chlorothiazide) is a thiazide diuretic oral suspension approved in 1961 that reduces blood pressure by increasing sodium and chloride excretion in the distal renal tubule.

It is a foundational antihypertensive agent with a well-established safety and efficacy profile across decades of clinical use.
