Overview

Nitric oxide + epoprostenol is a combination therapy consisting of inhaled nitric oxide (iNO) and inhaled epoprostenol (also known as prostacyclin or iPGI2). This combination has been investigated by Stanford University for the management of right ventricular failure and pulmonary hypertension in patients undergoing cardiac surgery, specifically heart transplantation or left ventricular assist device (LVAD) placement. Nitric oxide acts as a potent pulmonary vasodilator by stimulating soluble guanylate cyclase, which increases cyclic guanosine monophosphate (cGMP) levels in vascular smooth muscle. Epoprostenol acts through the prostacyclin receptor (IP receptor) to induce vasodilation and inhibit platelet aggregation via increased cyclic adenosine monophosphate (cAMP). The combined administration aims to achieve a synergistic reduction in pulmonary vascular resistance, thereby improving right heart function and hemodynamic stability in the post-operative period.
