Viagra: During sexual stimulation, nitric oxide is released in the corpus cavernosum and activates an enzyme that produces cyclic GMP. Viagra Professional: Sildenafil citrate inhibits PDE5, allowing the cyclic GMP produced during sexual arousal to accumulate in penile tissue, which relaxes the smooth muscle of the penile arteries and increases blood inflow.
