Vardenafil is used to treat male sexual function problems (impotence or erectile dysfunction-ED). In combination with sexual stimulation, vardenafil works by increasing blood flow to the penis to help a man get and keep an erection.
This drug does not protect against sexually transmitted diseases (such as HIV, hepatitis B, gonorrhea, syphilis). Practice "safe sex" such as using latex condoms. Consult your doctor or pharmacist for more details.
Vardenafil action is just like that of tadalafil and Sildenafil. It has the ability to control over the activity of this enzyme. Vardenafil stops the activity of this enzyme and improves the blood flow to the penis which makes it firm and erect. Simul, the blood vessels carrying blood away from the penis decrease in size and decrease the removal of blood from the penis. Erection can be easily achieved by using Vardenafil.
