Vidalista 80 mg blocks the PDE5 enzyme, preventing the breakdown of cyclic guanosine monophosphate (cGMP). This leads to relaxation of smooth muscles in penile blood vessels and increased blood flow, helping achieve and maintain an erection during sexual arousal. Sexual stimulation is still required for the drug to work. Tadalafil is known for its long duration of action, often lasting up to 36 hours. However, an 80 mg dose is significantly higher than standard recommended doses, and it does not necessarily improve effectiveness beyond normal therapeutic levels.
