WebJan 20, 2024 · Milrinone exerts positive inotropic actions by inhibiting PDE-3 in cardiac myocytes. PDE inhibition reduces the breakdown of intracellular cAMP, thereby enhancing calcium delivery and resulting in increased contractility. Milrinone also increases cGMP in vascular smooth muscle resulting in peripheral vasodilation.
