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 Sildenafil 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
