Angiotensin-converting enzyme inhibitor

Angiotensin-converting enzyme inhibitor

(Science: pharmacology) a class of drugs used in the treatment of hypertension and heart failure.

They exert their haemodynamic effect mainly by inhibiting the renin-angiotensin system and produce a reduction of peripheral arterial resistance. They also modulate sympathetic nervous system activity and increase prostaglandin synthesis. They cause mainly vasodilation and mild natriuresis without affecting heart rate and contractility.
