How do vasodilators treat pulmonary arterial hypertension (PAH)?

ANSWER

Vasodilators open up blood vessels, but some have an effect on the body for only a few minutes. To take the most common one, epoprostenol (Flolan, Veletri), you need a small battery-powered pump so you can get a steady dose.

Other vasodilators are medicines that you inhale, like iloprost (Ventavis) and treprostinil (Tyvaso). They go straight to your lungs and can quickly relieve shortness of breath.
