Amrinone is a pyridine phosphodiesterase 3 (PDE 3) inhibitor that is clinically used to treat congestive heart failure (CHF). Amrinone may be administered during cardiopulmonary bypass surgery. Amrinone exhibits positive inotropic activity, inducing vasodilation and increasing cardiac contractility through alterations in cAMP and Ca2+ signaling.
