Vidalista 60 mg blocks the PDE5 enzyme, which normally breaks down cyclic guanosine monophosphate (cGMP). When PDE5 is inhibited, cGMP levels increase, leading to relaxation of smooth muscles in penile blood vessels and improved blood circulation. This supports a stronger and more sustained erection, but sexual stimulation is still required for the drug to work. One of tadalafil’s key features is its long duration of action.
