Initially aimed at managing angina, Sildenafil citrate (Viagra) was Pfizer’s breakthrough discovery that shifted focus after trials revealed its potential for erectile dysfunction. It works by blocking PDE5, preserving cGMP levels, and promoting smooth muscle relaxation, a mechanism that improves blood flow and reduces strain. Approved in 1998, Viagra saw immediate success and became the gold standard for ED due to its consistent efficacy and good safety profile. Used by millions worldwide, its adaptability in dosing and well-tolerated effects have kept it at the forefront of ED therapies, influencing modern cardiovascular and sexual health treatments.
