Tadarise 2.5 mg operates by inhibiting the PDE5 enzyme, which normally breaks down cyclic guanosine monophosphate (cGMP). By preventing this breakdown, Tadalafil helps to maintain higher levels of cGMP in the body, leading to the relaxation of smooth muscles in the blood vessels of the penis. This relaxation allows for increased blood flow, facilitating an erection when a man is sexually aroused.
