Vigora 50 mg works by inhibiting the PDE5 enzyme in the body, which is responsible for breaking down cGMP (cyclic guanosine monophosphate). cGMP helps relax the smooth muscles and dilates the blood vessels in the penis. By inhibiting PDE5, Sildenafil Citrate helps increase cGMP levels, allowing more blood to flow into the penis, leading to a firmer and longer-lasting erection during sexual stimulation.
