Vidalista Professional works by inhibiting the enzyme phosphodiesterase type 5 (PDE5). PDE5 is responsible for breaking down cyclic guanosine monophosphate (cGMP), a substance that helps relax the smooth muscles in blood vessels, particularly in the penis. Tadalafil blocks this enzyme, which leads to increased levels of cGMP and results in improved blood flow to the penis. This helps men achieve and maintain an erection when they are sexually aroused.
