The Nemesis of Erectile Dysfunction: Sildenafil

Sildenafil was at first researched as a potential treatment for angina—or chest pain associated with inadequate blood flow to the heart—before being serendipitously indicated for treating erectile dysfunction in the late 1980s.

This medication has historically been most popularly recognized as Pfizer‘s brand name Viagra.

Viagra，as well as similar medications like Cialis (tadalafil), Levitra (vardenafil) and Stendra (avanafil), makes it easier for someone to get and keep an erection by improvingthe rate of blood flow to his penis.

Viagra is not recommended for use in women and adolescents younger than 18 years.
