Vidalista 2.5 mg works by inhibiting the PDE5 enzyme, which is responsible for breaking down cGMP (cyclic guanosine monophosphate) in the smooth muscle of the penis. By blocking PDE5, Tadalafil helps to maintain higher levels of cGMP, which in turn relaxes the blood vessels in the penis. This increased blood flow results in improved erectile function when a man is sexually aroused.
