Pillbox: Vardenafil
Brand names: Levitra
Type of drug: Phosphodiesterase type-5 (PDE-5) inhibitor
Used to treat: Erectile dysfunction
Notes: Erections are usually controlled by a balance of two body chemicals, one which causes erections and another which takes them away.
Vardenafil works by reducing the action of the second chemical (called PDE-5) and allows an erection to last long enough to satisfactorily complete sexual activity. It will only work when the patient is sexually stimulated.
