Thanks for that Peace, I wonder how long it takes for the generics to actually hit the market.
From wiki:
"A generic drug must contain the same active ingredients as the original formulation. According to the U.S. Food and Drug Administration (FDA), generic drugs are identical or within an acceptable bioequivalent range to the brand name counterpart with respect to pharmacokinetic and pharmacodynamic properties. By extension, therefore, generics are considered (by the FDA) identical in dose, strength, route of administration, safety, efficacy, and intended use.[3] The FDA's use of the word identical is very much a legal interpretation, and is not literal. In most cases, generic products are available once the patent protections afforded to the original developer have expired. When generic products become available, the market competition often leads to substantially lower prices for both the original brand name product and the generic forms. The time it takes a generic drug to appear on the market varies. In the US, drug patents give twenty years of protection, but they are applied for before clinical trials begin, so the effective life of a drug patent tends to be between seven and twelve years."
However for biologics, it's not so easy for a generic competitor:
"Because different manufacturers may produce slightly different products, they consequently cannot guarantee that their version is exactly as safe and effective as the original manufacturer's version. So, unlike most drugs, generic versions of biologics were not authorized in the United States or the European Union through the simplified procedures allowed for small-molecule generics. As a result, nearly all biologics have been brand-name therapeutics and required very extensive testing. Notable exceptions to this rule include several of the earliest biopharmaceuticals made via recombinant DNA technology, including biosynthetic 'human' insulin and human growth hormone."
