Vidalista 20's active ingredient, tadalafil, promotes blood flow to the erectile tissue, leading to an erection. During sexual stimulation, the erectile tissue of the penis releases nitric oxide, which activates the enzyme guanylate cyclase. This enzyme causes an erection by increasing the level of cyclic guanosine monophosphate, a chemical that relaxes the blood vessels in the penis and allows blood to flow into the spongy erectile tissues. If you are sexually stimulated, it can help you obtain an erection in 30-60 minutes that will last approximately 36 hours. It should be taken before scheduled sex. Vidalista 20 requires arousal to act properly.
