Doctors often use Vidalista Black to treat erectile dysfunction in men. Vidalista Black 80 contains the Phosphodiesterase type 5 (PDE-5) inhibitor tadalafil as its active component. Tadalafil increases blood flow to the penis and helps men develop and sustain an erection by blocking the enzyme PDE-5. This increases levels of cyclic Guanosine monophosphate (cGMP) and relaxes the muscles and blood vessels in the penis. Centurion Laboratories makes it. Vidalista Black 80 mg should be used exactly as recommended, and you should know about any adverse effects, pill interactions, or other precautions.
