Tadacip 20 mg is a PDE5 inhibitor (phosphodiesterase type 5 inhibitor), which means it works by blocking the enzyme PDE5. This enzyme can break down cGMP (cyclic guanosine monophosphate), a substance that helps relax the smooth muscles in the blood vessels of the penis. By inhibiting PDE5, Tadacip helps to maintain higher levels of cGMP, leading to relaxed blood vessels and increased blood flow to the penis during sexual activity, resulting in an erection.
