Vidalista 80 (which contains Tadalafil 80 mg) is not originally developed by a single inventor or company like a brand-new patented drug. It is a generic formulation based on the active ingredient tadalafil. Who originally developed it? The active drug tadalafil was originally: Discovered and developed through a collaboration involving ICOS Corporation and Eli Lilly and Company It was later marketed under the  Vidalista 80 name Cialis (approved in 2003) So, the original developers of tadalafil (the molecule) are ICOS Corporation and Eli Lilly. What about Vidalista 80 specifically? Vidalista 80 is a generic version, not the original branded drug It is manufactured by companies such as Centurion Laboratories (India) These companies did not invent tadalafil, they only produce generic versions in different strengths (like 80 mg) after the original patent allowed it Important clarification No single person or company “created Vidalista 80” It is a high-dose generic tadalafil tablet brand name The original scientific development belongs to ICOS + Eli Lilly, not Vidalista manufacturers Simple summary Original drug: Tadalafil (Cialis) → ICOS + Eli Lilly Vidalista 80: Generic product made later by Indian pharma companies If you want, I can also explain why 80 mg Vidalista is considered unusually high compared to standard tadalafil doses (10–20 mg) and what risks that involves.
