Which of the following is a thiazide diuretic with the brand name Diuril?

• A. Chlorothiazide
• B. Hydrochlorothiazide
• C. Chlorthalidone
• D. Indapamide

Answer: (A)

Thiazide diuretics work by blocking sodium reabsorption in the distal tubule, which helps reduce blood pressure and edema. The brand name Diuril is historically tied to chlorothiazide, so chlorothiazide is the thiazide associated with that brand. The other options are also thiazide diuretics, but they carry different brand names—hydrochlorothiazide is commonly Microzide, chlorthalidone is Thalitone, and indapamide is Lozide. So the drug linked to the brand Diuril is chlorothiazide.
