Epoprostenol is a synthetic analog of prostacyclin (PGI2), a potent vasodilator and inhibitor of platelet aggregation, primarily used for the treatment of pulmonary arterial hypertension (PAH). It is approved for intravenous administration in patients with severe PAH to improve exercise capacity and symptoms.
Pharmacokinetics
Pharmacokinetic parameters reported for healthy adult volunteers and patients with pulmonary arterial hypertension after intravenous infusion.
