Two medicines, side by side

Ramipril vs enalapril

Ramipril and enalapril are both labeled for high blood pressure. Drugs@FDA records approvals of ramipril since 1991 and of enalapril since 1985. Pharmacies paid $0.0707 per ramipril 10 mg capsule and $0.0664 per enalapril maleate 10 mg tablet (NADAC, October 7, 2026). How each works, in its label's words: Ramipril, “Ramipril and ramiprilat inhibit ACE in human subjects and animals.”; Enalapril, “Mechanism of Action Enalapril, after hydrolysis to enalaprilat, inhibits angiotensin-converting enzyme (ACE) in human subjects and animals.”

Used for

From the label: indications

Ramipril capsules are an angiotensin converting enzyme (ACE) inhibitor indicated for the treatment of hypertension, to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions. It may be used alone or in combination with thiazide diuretics ( 1.1 ). […]

How do ramipril and enalapril differ on the record?

How each works, in its label's words: Ramipril, “Ramipril and ramiprilat inhibit ACE in human subjects and animals.”; Enalapril, “Mechanism of Action Enalapril, after hydrolysis to enalaprilat, inhibits angiotensin-converting enzyme (ACE) in human subjects and animals.”

Both are in FDA's class angiotensin converting enzyme inhibitors.

Half-life, in each label's words: Ramipril, “The initial rapid decline, which represents distribution of the drug into a large peripheral compartment and subsequent …”; Enalapril, “The effective half-life for accumulation of enalaprilat following multiple doses of enalapril maleate is 11 hours.”

Both labels carry a boxed warning; the records quote them.

Generics: ramipril since 2005; enalapril since 2000 (Drugs@FDA).

How it works (label)Ramipril and ramiprilat inhibit ACE in human subjects and animals. Angiotensin converting enzyme is a peptidyl dipeptidase that catalyzes the conversion of angiotensin I to the vasoconstrictor substance, angiotensin II.Mechanism of Action Enalapril, after hydrolysis to enalaprilat, inhibits angiotensin-converting enzyme (ACE) in human subjects and animals.
Half-life (label)The initial rapid decline, which represents distribution of the drug into a large peripheral compartment and subsequent binding to both plasma and tissue ACE, has a half-life of 2 to 4 hours.The effective half-life for accumulation of enalaprilat following multiple doses of enalapril maleate is 11 hours.
