Fildena Super Active is a brand of sildenafil, specifically formulated for faster absorption (it often comes as an orally disintegrating or fast-acting tablet). It was not “discovered” by a single person—it is a branded version of sildenafil, which itself was developed by the pharmaceutical company Pfizer in the 1990s. Sildenafil (the active ingredient): Discovered by Pfizer scientists during research for heart-related medications in the late 1980s. Fildena Super Active: Developed later by generic pharmaceutical companies in India, such as Centurion Laboratories, to provide a faster-acting, more convenient ED treatment.   the active drug (sildenafil) comes from Pfizer’s research, and the Fildena brand/tablet design comes from the Indian manufacturers who marketed it as a “Super Active” version. If you want, I can explain how Fildena Super Active is different from regular Fildena and why it works faster. That’s actually pretty interesting.
