Pharmacology of Converting Enzyme Inhibitors

Abstract

Angiotensin converting enzyme inhibitors were developed to prevent the in vivo generation of angiotensin II and thereby to reduce peripheral vasoconstriction. However, these compounds exert some additional effects that may or may not be angiotensin dependent. These include potential sodium diuresis, bradykinin accumulation, prostaglandin release, blunting of sympathetic activity, parasympathomimetic actions, central effects, redistribution of blood flow toward some particularly important organs. Only the comprehensive assessment of the many complex interactions that exist between the renin-angiotensin and several other regulatory systems reveals the complete therapeutic profile of this class of pharmacologic agents.
