Under normal circumstances, upon sexual stimulation, nitric oxide (NO) is released in the corpus cavernosum.

NO activates the enzyme guanylate cyclase, which results in increased levels of cyclic guanosine monophosphate (cGMP). PDE5 breaks down cGMP, thus inhibiting erectile function; Viagra counters this by reducing the activity of PDE5, enhancing erectile response when a man is sexually stimulated. The primary mechanism by which Viagra operates is through the inhibition of the enzyme phosphodiesterase type 5 (PDE5), which is found predominantly in the corpus cavernosum, the spongy tissue of the penis.

In conclusion, Viagra is a pivotal medication in sexual medicine, primarily used to treat erectile dysfunction by enhancing the effects of nitric oxide in the penis.

Originally intended as a treatment for hypertension and angina pectoris, its notable side effect on erectile dysfunction (ED) redirected its course towards sexual health, marking a revolutionary step in its domain.
