Description: Captopril is an angiotensin-converting enzyme (ACE) inhibitor used for the treatment of hypertension and some types of congestive heart failure. Captopril was the first ACE inhibitor developed and was considered a breakthrough both because of its novel mechanism of action and also because of the revolutionary development process. Captopril was discovered and developed at Squibb and Sons Pharmaceuticals based on concepts pioneered by Nobel Laureate John Vane.
