Two medicines, side by side

Captopril vs lisinopril

Captopril and lisinopril are both labeled for high blood pressure and heart failure. Drugs@FDA records approvals of captopril since 1981 and of lisinopril since 1987. Pharmacies paid $0.228 per captopril 12.5 mg tablet and $0.0254 per lisinopril 20 mg tablet (NADAC, October 7, 2026); the strengths differ, so the two prices are not like for like. Lisinopril's other strengths are brand-only: $4.50 per mL (Qbrelis 1 mg/mL solution).

Check it at the source: the captopril FDA label on DailyMed (effective February 6, 2026); the lisinopril FDA label on DailyMed (effective January 2, 2025).

How do captopril and lisinopril differ on the record?

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

Half-life, in each label's words: Captopril, “The apparent elimination half-life for total radioactivity in blood is probably less than 3 hours.”; Lisinopril, “Upon multiple dosing, lisinopril exhibits an effective half-life of 12 hours.”

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

Generics: captopril since 1995; lisinopril since 2002 (Drugs@FDA).
