Levitra is used to treat erectile dysfunction, a common condition in men. The active ingredient in Levitra, vardenafil, works by relaxing muscles and increasing blood flow to the body. This helps men to get and maintain an erection.

Mechanism of Action
Levitra works by inhibiting the enzyme phosphodiesterase type 5 (PDE5). PDE5 is an enzyme that breaks down cyclic guanosine monophosphate (cGMP), a molecule that promotes muscle relaxation and blood flow in the body. By inhibiting PDE5, Levitra increases cGMP levels in the body, which helps to relax muscles and increase blood flow.
Levitra is rapidly absorbed after oral administration, with a mean maximum concentration (Cmax) of vardenafil reached in about an hour. Metabolism of vardenafil is primarily through CYP3A4, with minor contributions from CYP2C9 and CYP2B6. The major circulating metabolite is the M1 metabolite, which has a similar activity to vardenafil.
Elimination of vardenafil is primarily through hepatic metabolism, with a mean elimination half-life of 4-5 hours.
