Descriptions and Work Way of Viagra Sildenafil Citrate
Viagra is the brand name for sildenafil citrate, and is used for treating erectile dysfunction and pulmonary arterial hypertension. Originally developed by scientists in Great Britain, it was brought onto the market by Pfizer Inc., a US pharmaceutical company. Viagra is also sold under brand name Revatio. Sildenafil citrate's chemical formula is C22H30N6O4S.
Sildenafil citrate works by inhibiting an enzyme called cGMP-specific phosphodiesterase type 5, that delays degradation of cGMP, which controls blood flow in the penis.
