Application

Captopril has been used:
  • to examine the influence of timing of captopril treatment on efficacy in transverse aortic constriction (TAC) mice
  • as an angiotensin-converting enzyme inhibitor and orally administered to unrestrained Wistar Kyoto rats in an approach to study its effects of angiogenesis inhibition and interdependency with other drugs
  • used as a positive control in spectrophotometric assay to study the angiotensin-converting enzyme inhibitory activity

Biochem/physiol Actions

Captopril is known to decrease the cardiovascular complications arising due to myocardial infarction. It is an effective drug in treating diabetic nephropathy and renal disease. Captopril acts by reducing cardiac related inflammation, fibrosis and calcification.
Angiotensin converting enzyme inhibitor. Inhibits the formation of angiotensin II, a bioactive peptide that stimulates angiogenesis and increases microvessel density.
