Viagra – How does it Work?

Viagra works by releasing NO (Nitric Oxide) in the penis which affects the enzymes which then increases the release of cGMP, a salt, which helps smooth muscle relaxation and increases the blood flow and results in erection.

If erectile dysfunction has been observed for more than 25% of the time then it is a signal to consult the doctor. Erectile dysfunction may also be caused due to alcohol or use of tobacco so a change in lifestyle may also be needed along with drug usage. Some times depression and anxiety also become a cause of erectile dysfunction.
