MedKoo CAT#: 317311

CAS#: 73-48-3

Description: Bendroflumethiazide is a thiazide diuretic used to treat hypertension. Bendroflumethiazide works by inhibiting sodium reabsorption at the beginning of the distal convoluted tubule and may play an important role in the treatment of mild heart failure.
