Which is classified as an ACE inhibitor that is administered intravenously?

Enalaprilat is classified as an ACE inhibitor that is specifically administered intravenously. It is the active form of enalapril, which is an oral ACE inhibitor. The intravenous formulation allows for rapid control of blood pressure, making it particularly useful in acute situations such as hypertensive emergencies or when a patient cannot take oral medications.

While other agents listed, such as captopril, are ACE inhibitors, they are typically given orally. Moexipril is not available in an intravenous form either. Candesartan is actually an angiotensin II receptor blocker (ARB) and is also administered orally. Therefore, enalaprilat stands out as the only ACE inhibitor in the list that is designed for intravenous administration.
