What effect does Benazepril Hydrochloride have on aldosterone levels?

Benazepril Hydrochloride is an ACE inhibitor, which primarily works by obstructing the conversion of angiotensin I to angiotensin II. Angiotensin II plays a critical role in regulating blood pressure and fluid balance, and it is also a stimulant for aldosterone secretion from the adrenal glands. By inhibiting the formation of angiotensin II, Benazepril leads to decreased stimulation of aldosterone release. This reduction in aldosterone results in lower sodium and water retention, which can help reduce blood volume and lower blood pressure. Additionally, decreased aldosterone levels can mitigate related cardiovascular strain, making it a valuable medication in managing conditions like hypertension and heart failure.

In summary, the correct answer reflects the mechanism by which Benazepril affects aldosterone levels, ultimately leading to a decrease in serum aldosterone due to its inhibition of angiotensin II formation.
