Revatio® (sildenafil)
for Pulmonary Arterial Hypertension

Revatio (sildenafil) is used to treat pulmonary arterial hypertension (PAH) and improve exercise capacity in adults. It works by blocking the enzyme PDE5, which helps relax blood vessels. In the case of PAH, sildenafil relaxes the blood vessels in the lungs, lowering pulmonary blood pressure and reducing strain on the heart. This improved blood flow helps alleviate symptoms and increases exercise capacity.
