Anwendungen & Verwendung
Beschreibung
Captopril is the most studied of the angiotensin-converting enzyme inhibitors proposed as an antihypertensive drug. It blocks angiotensin-converting enzyme, which suppresses formation of angiotensin II and relieves its vasoconstricting effect on arterial and venous vessels. Overall vascular peripheral tension is reduced, which results in the lowering of arterial pressure.
Verwenden
Captopril has also been shown to inhibit the formation of angiotensin II, a bioactive peptide that stimulates angiogenesis and increases microvessel density. Captopril demonstrates noncompetitive inhibition of tyrosinase monophenolase activity and competitive inhibition of diphenolase activity
