Erectile dysfunction (also called impotence) means that you cannot get or maintain a proper erection. There are several causes, the most common being due to a narrowing of the arteries that take blood to the penis. Psychological factors such as stress, anxiety, guilt, depression, low self-esteem, and fear of sexual failure are also associated with impotence.
If the underlying condition leading to impotence cannot be corrected, or if impotence problems persist, medications can help men achieve erection sufficient for sexual Intercourse as well as maintain erection after penetration.
Viagra (Sildenafil Citrate) works by preventing the action of a chemical in the body called phosphodiesterase type 5. This helps to relax blood vessels and improves the flow of blood. As a result this helps to get and maintain a hard erection.
On average, Viagra becomes effective in just under an hour when you take a tablet on an empty stomach. Viagra can remain effective for between four and six hours. If you take it after a meal that has a high fat content, it may take longer than an hour to become effective.
