Vilitra 40mg (Vardenafil)
Vilitra 40 is an oral drug that is used to treat impotence or erectile
dysfunction, where a man can not attain or maintain an erection. An
erection is achieved when there is an engorgement of blood in the penis.

then activates the enzyme called guanylate cyclase to produce cyclic
guanosine monophosphate (cGMP). cGMP is responsible for the relaxation
of blood vessels, allowing blood flow to the penis, leading to an
Vilitra 40 contains 40mg of the active ingredient Vardenafil which is a phosphodiesterase-5 inhibitor. This drug works by inhibiting the action of the enzyme phosphodiesterase-5 (PDE-5) in destroying cGMP. As long as cGMP is available in the penis, the engorgement of blood in the penis lasts long.
Along with sexual stimulation, Vilitra can help a man get and maintain an erection needed for a sexual intercourse.
