Vidalista Black 80 mg is a medication used to treat erectile dysfunction (ED) in men. The active ingredient in Vidalista Black 80mg is Tadalafil, a Phosphodiesterase type 5 (PDE-5) inhibitor. Tadalafil works by inhibiting the PDE-5 enzyme, which leads to an increase in levels of cyclic Guanosine monophosphate (cGMP) and relaxation of the muscles and blood vessels in the penis, thereby increasing blood flow to the penis and helping men achieve and maintain an erection. It is manufactured by Centurion Laboratories. It is important to take Vidalista Black 80 mg as prescribed by a doctor and to be aware of potential side effects, interactions with other medications, and precautions.
