Pharmacology & Mechanism of Action
Captopril is a sulfhydryl-containing analog of proline with antihypertensive activity. Captopril competitively inhibits angiotensin converting enzyme (ACE), thereby decreasing levels of angiotensin II, increasing plasma renin activity, and decreasing aldosterone secretion. Approxiately 60-75% of an oral dose of captopril is repidly absorbed from the GI tract in fasting healthy individuals or hypertensive patients. More than 95% of a dose is excreted renally, both as unchanged (45-50%) drug and as metabolites.
