What Is Viagra for Erectile Dysfunction?
Viagra, the brand name for sildenafil, is an FDA‑approved erectile dysfunction medication that helps men get firmer, longer-lasting erections. It does not increase sexual desire; instead, it supports the body’s natural erectile response by allowing more blood flow to the penis during arousal.
How Viagra Works in Men
Viagra sildenafil works by blocking PDE5, an enzyme that restricts blood flow in penile tissue. When PDE5 is inhibited, blood vessels relax, allowing stronger and more sustained erections during sexual stimulation.
