Answer

Vasodilators

These agents have vasodilatory effects.

Epoprostenol (Flolan, Veletri)

Epoprostenol, an analogue of prostacyclin (PGI2), has potent vasodilatory properties, an immediate onset of action, and a half-life of approximately 5 minutes. In addition to its action as a vasodilator, epoprostenol also contributes to the inhibition of platelet aggregation and plays a role in the inhibition of smooth muscle proliferation. [46]

Long-term infusion of this drug improves the outcome in patients with primary pulmonary hypertension and in selected patients with secondary pulmonary hypertension. A short-term vasodilatory response appears to be unrelated because favorable impact on disease progression occurs with long-term therapy.

The dose is determined during a dose/effect study performed in the catheterization laboratory or the intensive care unit (ICU). The selected dose should produce maximum vasodilation with minimal systemic hypotension.
