Sildenafil (Viagra) is used to treat erectile dysfunction in men (impotence; inability to get or keep an erection). Sildenafil (Revatio) is used to improve exercise capacity in adults with pulmonary hypertension (PHT; high blood pressure in the vessels that carry blood to the lungs, causing shortness of breath, dizziness, and tiredness). Sildenafil should not be used in children. Sildenafil is in a class of drugs called phosphodiesterase (PDE) inhibitors. Sildenafil is used to treat erectile dysfunction by increasing blood flow to the penis during sexual stimulation. That increased blood flow can lead to an erection. Sildenafil treats PHT by relaxing the blood vessels in the lungs to allow blood to flow easily.
