Viagra is a phosphodiesterase-5inhibitor drug that is used to treat impotence among men. The “little blue pill” as most men call it, is an instant solution for sexually active men who cannot manage an erection by themselves.
Apart from its commonly known use for impotence, it is also an effective drug to treat a rare condition called pulmonary arterial hypertension by relaxing the pulmonary arterial wall and promoting decreased pulmonary resistance and pressure ensuring adequate blood flow to the lungs. This drug can also be used to treat altitude sickness and high-altitude pulmonary edema.
