Sildenafil citrate (sildenafil), popularly known as "generic Viagra," has the same active ingredient as "brand-name Viagra." Trace amounts of inactive chemicals are also included in Viagra. These elements both give the pill its form and make it easier for the body to digest the pills. One of the primary causes of ED is an accumulation of the PDE5 enzyme, which reduces or inhibits the firmness of an erection by restricting blood supply to the genital. Sildenafil inhibits PDE5, resulting in more unrestricted blood flow and a higher chance of erection.
