Field: V-phosphodiesterase inhibitors

It is an oral drug for male erectile dysfunction. It was accidentally discovered when the American Pfizer Pharmaceutical Company developed a 5-phosphodiesterase inhibitor for cardiovascular diseases that it can improve the sexual life of patients. In March 1998, the U.S. Food and Drug Administration approved a drug for male erectile dysfunction, becoming an oral drug specifically used clinically for male erectile dysfunction.

Sildenafil uses

It is a selective inhibitor of phosphodiesterase (PDE) V and can enhance the physiological response of penile erection caused by NO release under sexual stimulation. Mainly used for penile erectile dysfunction
