Brand-name drugs have an average market exclusivity of 12.5 years. Those generics with 6-month patent exclusivity may be as expensive as their brand innovators’ drugs. 20-22 The price of generics that are available immediately from multisource (four or more) generic manufacturers should be drastically reduced as soon as they come to market. New generics available or expected in the U.S. have been proposed, as have alternative pricing models for generic drugs.
6 Options to promote competitive generic markets in the U.S. 17,18 Turing, Valeant, Retrophin, and Rodelis Therapeutics are all being investigated by a Congressional committee for price gouging after purchasing the rights to manufacture and distribute off-patent generic medications. Mergers and acquisitions among generic manufacturers, supply disruption, and increased regulation all contribute to the rising prices of generics ( Table 1). 14 Market exclusivity incorporates the life of the patent, the minimum exclusivity period stipulated by the Hatch-Waxman Act, the remaining time on the original patent covering the active principle, and other factors that affect generic entry. This article, however, will focus on traditional generic drugs that are in the pipeline.īy definition, market exclusivity is the time between FDA approval to market a brand drug and the market availability of a generic formulation of that drug. Pegfilgrastim, adalimumab, rituximab, bevacizumab, and trastuzumab are currently in development. Insulin glargine (Basaglar) and infliximab (Inflectra) are FDA-approved but were not yet available at press time. Filgrastim (Zarxio) is currently available. 12 Colony-stimulating factors and antitumor necrosis factor products are expected in 2016. pipeline include antitumor necrosis factor products, short- and long-acting insulins, antineoplastics, colony-stimulating factors, interferons, and erythropoietins. 12,13 Biosimilars are already widely available in Europe. 9-11 Biosimilars may or may not afford similar cost savings owing to the extensive development program they require compared to generic medicines, as well as a different naming convention. via a different abbreviated pathway and nomenclature. It also provided a naming convention, allowing generic medications to share the “generic” name of the innovator’s drug.īiosimilars, as defined by the Affordable Care Act (ACA) of 2010 and the Biologics Price Competition and Innovation Act (BPCIA) of 2009, are FDA-approved to market in the U.S. 8 This simplified the process for ensuring efficacy and safety of new generics by resting an Abbreviated New Drug Application in the original New Drug Application for an innovator’s branded drug. In 1984, generic drugs were defined by revisions to the Federal Food, Drug, and Cosmetic Act of 1978 with the Drug Price Competition and Patent Term Restoration Act (known as the Hatch-Waxman Act). 5-7 These generic drug prices depend on many market factors that affect supply and demand, including drug shortages and competition.
3,4 Yet in the United States there has been a substantial increase in the cost of generic medications over the last 2 years. 2 The acquisition cost of generic drugs for healthcare organizations traditionally ranges from 20% to 80% lower than the innovators’ branded drugs. 1 Generic medications offer patients and insurers alike significant monetary savings that in turn contribute to more affordable healthcare markets. Global healthcare costs currently exceed US $1 trillion annually, with generic drugs making up $435 billion of this global market. healthcare industry billions of dollars and have a significant therapeutic impact. Despite substantial increases in the cost of generic medications over the last 10 years, new multisource generics have the potential to save the U.S. Managed care organizations leverage generic medications to improve utilization by carefully selecting tiered formulary pricing. 2016 41(6)(Generics suppl)12-19.ĪBSTRACT: Healthcare systems in the United States leverage generic medications as a means to control the pharmaceutical budget with tools that include formulary guidelines, restrictions, and therapeutic interchange programs.
