Description: Ralinepag (APD-811) is an orally available agonist of the prostacyclin (IP) receptor intended for the treatment of vasospastic diseases such as Pulmonary Arterial Hypertension. Ralinepag has the potential to mimic prostacyclin -- the major product of cyclooxygenase -- in macrovascular endothelium This elicits a potent vasodilation response and inhibition of platelet aggregation when binding to this receptor.
