Product Overview

Developed by Pfizer, Sildenafil citrate—better known as Viagra—was synthesized in 1989 and originally researched for angina treatment. It operates by inhibiting the enzyme PDE5 to sustain cGMP levels in smooth muscle cells, which facilitates relaxation and increased blood flow. Viagra was later repurposed for erectile dysfunction after showing positive results in related studies, receiving approval in 1998. Its proven effectiveness, along with dosage options, allows tailored treatment for users. With its high success rate and limited side effects, Viagra became the standard of care, trusted by millions for treating ED effectively.
