Chemical Properties
Benazepril Hydrochloride is an angiotensin-converting enzyme inhibitor (ACEI). Upon oral administration, it is rapidly absorbed and converted to its active metabolite, benazeprilat. By inhibiting the activity of angiotensin-converting enzyme, it reduces the formation of angiotensin II, thereby lowering blood pressure, reducing cardiac load, and improving cardiac function.
Uses
Benazepril Hydrochloride is primarily used for the treatment of hypertension and congestive heart failure. It can also serve as an adjunctive therapy for patients with congestive heart failure who are not adequately responsive to digitalis and/or diuretics.
