Identification
Common NameQuinapril hydrochloride
ClassSmall Molecule
DescriptionA hydrochloride resulting from the reaction of equimolar amounts of quinapril and hydrogen chloride. A prodrug for quinaprilat hydrochloride (by hydrolysis of the ethyl ester to the corresponding carboxylic acid), it is used as an angiotensin-converting enzyme inhibitor (ACE inhibitor) for the treatment of hypertension and congestive heart failure.
