Olprinone (CAT: I000326), also known as Loprinone, is a selective inhibitor of phosphodiesterase 3 (PDE3). By inhibiting PDE3, Olprinone prevents the breakdown of cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) in cells. This leads to increased intracellular levels of cAMP and cGMP, which in turn can have various pharmacological effects. Olprinone is primarily used as an inotropic agent and vasodilator in the treatment of heart failure and pulmonary hypertension. Its inhibition of PDE3 activity results in positive inotropic effects and vasodilation, contributing to improved cardiac function and reduced vascular resistance.
