Tadalis SX 20 mg works by inhibiting the action of PDE5, an enzyme that restricts the flow of blood to the penis. When a man is sexually aroused, the body naturally releases nitric oxide, which increases the levels of cGMP (cyclic guanosine monophosphate) in the blood vessels. cGMP helps relax the blood vessels in the penis, allowing more blood to flow and thereby helping to achieve and maintain an erection. By blocking PDE5, Tadalis SX helps prolong the effects of cGMP, enhancing erectile function.
