What is Viagra? Viagra is a prescription drug with an active ingredient of sildenafil. It assists men with erectile dysfunction (ED) by enhancing blood flow to the penis upon sexual stimulation. This is because Viagra eases muscles in the walls of blood vessels so more blood can circulate where it is required to support an erection. Approved by the U.S. FDA in 1998, Viagra is used as a tablet and should be taken approximately one hour before sex. It doesn't stimulate sexual desire and is only effective when a man is sexually aroused. Viagra is a treatment for ED that lasts for only a short while, but it can enhance sexual performance if it is used responsibly. How Viagra USA Works Viagra, whose active ingredient is sildenafil, treats erectile dysfunction by enhancing blood flow to the penis. When a person becomes sexually aroused, the body releases a chemical that relaxes the blood vessels and enhances blood flow. Viagra facilitates this process through preventing an enzyme called PDE5, which is responsible for breaking down the molecule needed for an erection. By keeping this molecule active longer, Viagra allows blood to flow more easily, helping a man get and maintain an erection. It only works when there is sexual stimulation and doesn’t create arousal on its own. Taken about 30 to 60 minutes before activity, Viagra can remain effective for several hours.
