Benazepril HCI is a prescription medication used to treat heart failure, high blood pressure, and some forms of kidney disease. It helps by blocking a natural enzyme called angiotensin, which is normally part of a reaction in the body that causes the blood vessels to narrow. When medication blocks this enzyme, it allows blood vessels to relax and dilate, which may lower blood pressure. Customers may receive this drug under the names Fortekor, Lotensin.


Benazepril hydrochloride tablets (USP certified) are indicated for the treatment of hypertension. Benazepril hydrochloride tablets may be used alone or in combination with thiazide diuretics.
