Viagra, or Sildenafil citrate, was developed by Pfizer to selectively inhibit PDE5 and enhance blood flow through the NO/cGMP pathway, easing conditions associated with poor vascular function. Although the original focus was on angina, Viagra’s unique properties proved especially beneficial for erectile dysfunction, leading to its approval in 1998. It helps by maintaining cGMP in the smooth muscle cells, resulting in relaxed vascular muscles and increased circulation. As the first PDE5 inhibitor on the market, Viagra set a new standard for ED treatment, and remains the most widely studied and trusted medication for the condition.
