Description
What is Viagra 50mg?
Viagra 50mg contains the active ingredient sildenafil citrate and is prescribed for the treatment of erectile dysfunction (ED) in adult men.
It works by improving blood flow to the penis during sexual stimulation, enabling a firm and sustained erection.
The 50mg dose is typically recommended as the standard starting dose for most men, balancing efficacy with tolerability.
How Viagra 50mg Works
Viagra inhibits phosphodiesterase type 5 (PDE5), increasing cyclic GMP (cGMP) levels in penile tissue. This relaxes smooth muscles in the corpora cavernosa, allowing blood to flow into the penis for an erection.
Mechanistic details are available in Cleveland Clinic’s ED medication guide.
