Originally synthesized at Pfizer’s UK laboratories in 1989, sildenafil citrate was designed to treat angina through PDE5 inhibition. Though it did not fulfill its cardiovascular goal, the drug unexpectedly improved erectile response in clinical trials. This led to its repositioning and rebranding as Viagra, approved in 1998. Clinical success, confirmed by 21 efficacy studies, cemented Viagra as the leading treatment for erectile dysfunction, praised for its tolerability and consistent performance.
