Levitra is a medicine used in the treatment of erectile dysfunction. The active ingredient of the medicine is a drug known as vardenafil. Levitra works by inhibiting an enzyme known as PDE5, allowing blood vessels to dilate and increase blood flow around the body. However, this effect works over the entire body, meaning blood pressure can drop sharply; a potential problem for those with existing heart disease.
Levitra (Vardenafil) is a phosphodiesterase type 5(PDE5) inhibitor. Levitra is used to treat male sexual function problems including impotence and erectile dysfunction. In combination with sexual stimulation, Levitra works by increasing the amount of blood that reaches the penis, thereby allowing the man to get and maintain a firm erection for penetration.
Levitra helps the body release nitric oxide in the vasculature of corpus cavernosum when the penis is stimulated. Nitric oxide then activates an enzyme known as guanylate cyclase, which then triggers the increase of cyclic guanosine monophosphate, an action that leads to the relaxation of the blood vessels supplying blood to the penis.
