Nitric oxide allows the smooth muscles inside the penis to relax, promoting more blood flow to the area during sexual arousal or stimulation. Through this action, the drugs work to fix a functional problem. The use of Viagra-like drugs in women is not so straightforward and a similar treatment does not exist for women. Viagra may help women who report having difficulties with lubrication because the increase in blood flow to the female genitals would subsequently increase lubrication. However, this use is not approved by the U.S. Food and Drug Administration. In addition, in most cases the problem for women is not with physical arousal but rather a lack of sexual desire. Scientists are looking at other drugs in women with sexual dysfunction who either say they're uninterested in sex or that sex provides little pleasure.

Sildenafil (Viagra) is used to treat erectile dysfunction (impotence; inability to get or keep an erection) in men. Sildenafil (Revatio) is used to improve the ability to exercise in adults with pulmonary arterial hypertension (PAH; high blood pressure in the vessels carrying blood to the lungs, causing shortness of breath, dizziness, and tiredness). Children should not usually take sildenafil, but in some cases, a doctor may decide that sildenafil (Revatio) is the best medication to treat a child's condition. Sildenafil is in a class of medications called phosphodiesterase (PDE) inhibitors. Sildenafil treats erectile dysfunction by increasing blood flow to the penis during sexual stimulation. This increased blood flow can cause an erection. Sildenafil treats PAH by relaxing the blood vessels in the lungs to allow blood to flow easily.
