How does Vega 100 mg work?

Vega 100 mg works in combination with sexual stimulation. It increases the blood flow to the penis by relaxing the smooth muscles present in the walls of the blood vessels and helps the person get and maintain an erection.

It is a PDE 5 inhibitor, meaning it blocks the action of PDE 5 and enables the production of cGMP (cyclic guanosine monophosphate). The production of cGMP allows the blood to flow easily to the penis. As more and more blood flows to the penis, pressure is created in the penis that leads to an erection.
