What is Levitra?

Levitra is a prescription medication used to treat erectile dysfunction (ED). Levitra belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. These drugs work by relaxing muscles and increasing blood flow in the body.


Health Benefits

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.

Levitra has been shown to be effective in treating ED in men of all ages, including those with diabetes or prostate surgery. Levitra may also be effective in treating other conditions that cause ED, such as depression or anxiety.

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.
