Description and Uses

Captopril disulfide is a metabolite and symmetrical disulfide form of the angiotensin converting enzyme (ACE) inhibitor captopril . Captopril disulfide is the main degradation product of captopril and is formed by oxidation. It is a potential impurity in commercial preparations of captopril. Captopril disulfide inhibits angiotensin I-induced increases in mean arterial pressure in anesthetized dogs (ID₅₀ = 0.231 mg/kg, i.v.).

Captopril Disulfide (Captopril EP Impurity A) is a metabolite of Captopril. A new antihypertensive agent.
