Caverta, Sildenafil

Caverta works for 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).

Caverta for patients with erectile dysfunction, works by preventing the action of a chemical called, phosphodiesterase type-5. This works 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 Pulmonary arterial hypertension or PAH Caverta 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
