General Description
Sildenafil, sold as the brand name Viagra among others, is a medication used to treat erectile dysfunction and pulmonary arterial hypertension.[3] It is unclear if it is effective for treating sexual dysfunction in women.[3] It is taken by mouth or injection into a vein.[3] Onset is typically within 20 minutes and lasts for about 2 hours.[3] Common side effects include headaches, heartburn, and flushed skin.[3] Caution is advised in those with cardiovascular disease.[3] Rare but serious side effects include a prolonged erection that can lead to damage to the penis, vision problems, and hearing loss.[3] 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.[3] Sildenafil acts by blocking phosphodiesterase 5 (PDE5), an enzyme that promotes breakdown of cGMP, which regulates blood flow in the penis.[3] It requires sexual arousal, however, to work.[3] It also results in dilation of the blood vessels in the lungs.
