Drug Pricing: Research on Savings from Generic Drug Use

摘要

Prescription drug spending in the United States reached $307 billion in 2010--an increase of $135 billion since 2001--and comprised approximately 12 percent of all health care spending in the country. Until the early 2000s, drug spending was one of the fastest growing components of health care spending. However, since that time, the rate of increase has generally declined each year, attributable in part to the greater use of generic drugs, which are copies of approved brand-name drugs. Generic versions of brand-name drugs become available to consumers when brand-name drugs patents and periods of market exclusivity expire and generic manufacturers obtain approval to market their drug. The competition that brand-name drugs face from generic equivalents is associated with lower overall drug prices, particularly as the number of generic manufacturers grows and price competition among them increases. On average, the retail price of a generic drug is 75 percent lower than the retail price of a brand-name drug.
