Uses

Viagra helps in the treatment of erectile dysfunction or impotence or inability to get or keep an erection during sexual activity. It is also used to improve exercise capacity in men and women with Pulmonary arterial hypertension (PAH) (high blood pressure in the arteries carrying blood to the lungs from the heart).

How it Works

Viagra for patients with erectile dysfunction, works by preventing the action of a chemical in your body, phosphodiesterase type-5. This then  helps to widen and relax the muscles in blood vessels in the penis and increases blood flow. This helps to produce and maintain an erection for people suffering with erectile dysfunction problems.For Pulmonary arterial hypertension or PAH Viagra works by relaxing the muscles in the walls of the arteries, which then allows the blood vessels to become wider, This reduces the pressure in the arteries and allows blood to flow more easily through them. This then increases the supply of blood to the lungs and directly improves the ability to do exercise
