Captopril is an angiotensin-converting enzyme (ACE) inhibitor (IC₅₀ = 0.022 μM). Also inhibits the bifunctional Zn2+-containing leukotriene A4 hydrolase/aminopeptidase (LTA4 hydrolase) reversibly and competitively (Ki = 6.0 μM for leukotriene B4> formation and Ki = 60 nM for L-lysine-p-nitroanilide). Displays vasodilatory and antihypertensive effects in vivo. Clinically useful antihypertensive agent.
