Does sildenafil interact with foods or drinks?
While a drug is under patent, no other potential “competitors” can develop, manufacture or market the same active ingredient. For example, with Viagra (the branded form) under patent, no company would be able to develop, manufacture or market any form of sildenafil (the generic form).When patents expire (which was the case in 2012 for Viagra), other companies or brands can begin manufacturing and marketing their own versions of a drug, referred to as generic medications. These generic medications cannot use the Viagra name or branding, but contain the same active ingredient, the chemical compound sildenafil. Generic vs branded drug approval: in a nutshellGeneric versions of medications that are marketed in North America must apply for and receive FDA (in the USA, or Health Canada in Canada) approval.
