Viagra, or sildenafil, primarily treats erectile dysfunction (ED), characterized by the inability to achieve or maintain an erection firm enough for satisfactory sexual intercourse. This medication enhances the effects of nitric oxide, a naturally occurring substance that relaxes muscles in the penis, increasing blood flow.
Beyond ED, Viagra also finds application in treating pulmonary arterial hypertension (PAH), a condition where blood pressure in the arteries leading to the lungs becomes abnormally high. This off-label use leverages Viagra’s ability to relax blood vessels, reducing strain on the heart and improving blood flow to the lungs.

| Pulmonary Arterial Hypertension | Dilates blood vessels in the lungs, reducing pulmonary vascular resistance. | Requires careful monitoring due to potential side effects; prescribed only under strict medical supervision. |
