The
Vidalista Black 80mg drug works by inhibiting PDE5. This increases the amount of a chemical in the blood that helps you have an erection. This chemical is cyclic guanosine monophosphate (cGMP). Sexual stimulation causes nitric oxide to be released from the nerve terminals and endothelial cells in your penile arteries, which in turn causes cGMP levels in smooth muscle cells of the corpus cavernosum to rise. This causes the muscle to relax and increases blood flow into the penile area.
