NO is a natural chemical that relaxes muscles in the penis, increases blood flow, and allows for an erection in response to sexual stimulation. Elevated levels of cGMP lead to smooth muscle relaxation and increased blood flow to the penis, facilitating the erection process. Viagra works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which results in an increase in the levels of cyclic guanosine monophosphate (cGMP). The mechanism of action of Viagra involves the enhancement of nitric oxide (NO) effects in the corpus cavernosum of the penis.

The primary mechanism through which Viagra operates is by inhibiting an enzyme called phosphodiesterase type 5 (PDE5). Normally, PDE5 breaks down cyclic guanosine monophosphate (cGMP), a substance that is responsible for smooth muscle relaxation in the corpus cavernosum of the penis. By inhibiting PDE5, Viagra increases the levels of cGMP, thus enhancing the natural process of erection during sexual stimulation by allowing increased blood flow into the penis.
