Tadacip works by inhibiting the enzyme PDE5, which is responsible for breaking down cGMP (cyclic guanosine monophosphate). cGMP helps relax the smooth muscles in the blood vessels of the penis, allowing them to expand and increase blood flow. By blocking PDE5, Tadacip helps maintain higher levels of cGMP, improving blood flow to the penis and making it easier to achieve and maintain an erection.
