Generic Viagra (Sildenafil Citrate)

Generic Viagra (Sildenafil Citrate) is a medication used to treat erectile dysfunction and pulmonary arterial hypertension. It is taken by mouth. Onset is typically within 20 minutes and lasts for about 2 hours.

Sildenafil acts by blocking phosphodiesterase 5 (PDE5), an enzyme that promotes breakdown of cGMP, which regulates blood flow in the penis. It requires sexual arousal, however, to work. It also results in dilation of the blood vessels in the lungs.

Possible side effects:

Common side effects include headaches, heartburn, and flushed skin. Caution is advised in those with cardiovascular disease.

Rare but serious side effects include a prolonged erection that can lead to damage to the penis, vision problems, and hearing loss.

Sildenafil should not be taken by people on nitrates such as nitroglycerin (glycerin trinitrate), as this may result in a serious drop in blood pressure.

Sexual dysfunction

The primary indication of sildenafil is treatment of erectile dysfunction (inability to sustain a satisfactory erection to complete intercourse). Its use is now one of the standard treatments for erectile dysfunction, including for men with diabetes mellitus.
