Notes: Captopril is an inhibitor of angiotensin-converting enzyme (ACE; IC50 = 23 nM for the rabbit lung enzyme).{42208,52244} It inhibits contractions in isolated guinea pig ileal segments induced by angiotensin I or bradykinin (IC50s = 23 and 3 nM, respectively) but not those induced by angiotensin II, histamine, acetylcholine, serotonin (5-HT), or prostaglandin E1 (PGE1; IC50s = >10 µM for all).{52244} Captopril (0.1-1 mg/kg) inhibits angiotensin I-induced pressor responses in conscious normotensive rats.{42208} It reduces mean blood pressure in two kidney-one clip renal hypertensive (2K-1C) rats and spontaneously hypertensive rats (SHRs). Captopril also reduces cytopathogenicity induced by herpes simplex virus 1 (HSV-1) in SH-SY5Y human neuroblastoma cells.{61145} Formulations containing captopril have been used in the treatment of hypertension, congestive heart failure, and diabetic nephropathy.
