Viagra (sildenafil) is used for the treatment of erectile dysfunction. Viagra works by inhibiting the chemical phosphodiesterase, which leads to an increase in the effect of nitric oxide. Nitric oxide allows the smooth muscles inside the penis to relax, promoting more blood flow to the area during sexual arousal or stimulation. Viagra begins to work within about an hour and the effects can last for up to four hours.
