The drug works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which is responsible for degrading the messenger cyclic guanosine monophosphate (cGMP). By inhibiting this enzyme, Vidalista increases cGMP levels, which improves the relaxation of the muscles in the walls of the blood vessels and increases blood flow to the penis. This, in turn, helps to create an erection when sexual stimulation occurs. https://medzpills.com/product/vidalista-20_mg-tadalafil-india/
