Rx Watchdog Report: Brand Name Drug Prices Continue to Climb Despite Low General Inflation Rate

These AARP Public Policy Institute reports present the most recent results of studies of changes in manufacturers' prescription drug list prices (i.e., the prices set by drug manufacturers to charge wholesalers and other direct purchasers for drug products) for prescription drugs. These reports are based on drugs widely used by Medicare beneficiaries; previous reports were based on utilization patterns for older Americans in general.

Specifically, the reports compare price changes with the rate of inflation. They also present differences in average price changes by manufacturer and by major therapeutic category. The sample of drugs studied was identified using 2006 data from a Medicare Part D plan provider, and changes in prices charged by drug manufacturers to wholesalers were measured using changes in the wholesale acquisition cost (WAC).

For more information, please contact Leigh Purvis at (202) 434-3902.
