Viagra is a medicine typically used to treat erectile dysfunction and pulmonary arterial hypertension. Erectile dysfunction is the inability to maintain or attain an erection adequate for the sexual satisfaction of both partners. Viagra is the brand name for sildenafil. Sildenafil was patented in 1996.
Viagra was approved by the US FDA for use as an ED drug in 1998. It is taken orally or by injection into a vein. Its onset is typically within 20 minutes, and the effects last for around 2 hours. Viagra works by helping to relax muscles and arteries inside the penis, allowing more blood to reach the penis. When aroused, the combination of increased blood flow and relaxation helps fill the penis with blood.
Viagra is primarily used to treat erectile dysfunction by helping one achieve and maintain an erection. The drug improves blood flow into your penis when you are sexually aroused. It is a kind of drug called a phosphodiesterase type 5 ( PDE 5 ) inhibitor. It acts by inhibiting ( or blocking ) the action of an enzyme known as PDE 5. But, using Viagra ( or sildenafil ) recreationally is not advisable. Healthy men should not take Viagra for fun due to the health risks. Viagra use in healthy men has shown no erection or pleasure benefit.
Viagra may cause your blood pressure to drop abruptly to an unsafe level if you take it with certain other medicines. Don't take Viagra if you take any other medications known as nitrates. Nitrates are generally used to treat chest pain ( or angina ). A sudden drop in blood pressure may cause you to feel faint, dizzy, or have a stroke or heart attack. Don't take Viagra if you take medicines called guanylate cyclase stimulators. If you need emergency medical treatment for a heart problem, it will be essential for your doctor to know when you last took Viagra.
Stop sexual activity and seek medical care right away if you experience dizziness, chest pain, or nausea during sex. Sexual activity puts an extra strain on the heart, especially if the heart is already weak from heart disease or heart attack. Ask the health care expert if your heart is healthy enough to handle the added strain of having sex. Viagra doesn't protect you or your partner from getting STDs or sexually transmitted diseases, including HIV, i.e., the virus that causes AIDS. Do not take this drug if you are allergic to sildenafil, which is contained in Viagra, or any of the ingredients in Viagra.
