Viagra (Sildenafil)

How does Viagra work?

Erectile dysfunction is a common sexual problem for men, it affects as many as 30 million men. It is the difficulty of men to get or keep an erection. It occurs when the blood flow in the penis is limited or when the penile nerves are harmed. It can happen due to stress, depression or other emotional disturbances. It can also be due to physical diseases, injury or a side effect of other medications. Viagra contains the active ingredient, sildenafil citrate, which belongs to a family of medicines call PDE5 inhibitors, which help to relax the blood vessels in your penis. Viagra works by increasing the blood flow to the penis so a man can get an erection and maintain it. It only works when you are sexually stimulated and after you have had sex the erection should go away. It last up to 5 hours.
