Tadarise 5 mg works by inhibiting the enzyme PDE5, which regulates blood flow in the penis. When a man is sexually stimulated, the body releases nitric oxide (NO), leading to increased levels of cyclic guanosine monophosphate (cGMP). cGMP relaxes the blood vessels in the penis, allowing increased blood flow, which results in an erection. By inhibiting PDE5, Tadarise enhances the effects of cGMP, thereby improving erectile function.
