Vardenafil is used to treat erectile dysfunction in men. Vardenafil is in a class of medications called phosphodiesterase (PDE) inhibitors. It works by increasing blood flow to the penis during sexual stimulation. This increased blood flow can cause an erection. Vardenafil 40mg does not cure erectile dysfunction or increase sexual desire. Also it does not prevent pregnancy or the spread of sexually transmitted diseases such as HIV.
It is the main active ingredient of well-known Levitra and all its generics, such as Levitra jelly 20 mg. Distinctive features of the drug are its speed, efficiency regardless of age and good tolerability.
