Medical Definition of sildenafil
Note: Sildenafil inhibits a phosphodiesterase enzyme that degrades cyclic GMP. Higher levels of cyclic GMP in the body promote relaxation of smooth muscle, which allows for increased blood flow to the lungs to lower blood pressure and to the corpus cavernosum to produce an erection during sexual arousal. Sildenafil is marketed under the trademark Viagra to treat erectile dysfunction and under the trademark Revatio to treat pulmonary arterial hypertension.
