Sildenafil citrate, marketed as Viagra, is a PDE5 inhibitor that emerged from Pfizer’s cardiovascular research in the 1980s. Originally focused on angina, the compound was later adapted for erectile dysfunction due to its beneficial effects on blood flow. Viagra works through the NO/cGMP pathway, preventing cGMP breakdown in smooth muscles, which allows blood vessels to dilate effectively. Following its 1998 release, it became the leading ED medication, providing flexible dosing to suit patient needs. With over 20 million users, Viagra remains the premier choice for safe, reliable, and effective ED treatment, often outperforming alternatives.
