What is Revatio used for?

Revatio is used to treat pulmonary arterial hypertension (high blood pressure in the blood vessels between the heart and the lungs) in adults of 18 years of age or above. Revatio also improves the ability to exercise and slows down the worsening of your physical condition and symptoms of pulmonary hypertension. In pulmonary arterial hypertension, the blood pressure in the lungs is too high. Your heart has to work hard to pump the blood into your lungs. Revatio belongs to a class of drugs known as phosphodiesterase type 5 inhibitors. It brings down the pulmonary (lung) blood pressure by widening and relaxing these blood vessels. Always take Revatio exactly as prescribed by your doctor. The usual recommended dose of Revatio is 20 mg three times a day (taken 6 to 8 hours apart), swallowed with or without food.
