A new study released by AARP finds manufacturers' wholesale prices for the 197 brand name prescription drugs most frequently used by older Americans continued an upward climb.
Prices rose 3.4 percent during the three-month period ending March 31, 2004 compared to a 1.2 percent rate of general inflation for the same period. The average annual rate of increase rose from 6.9 percent for the 12 months ending December 2003 to 7.2 percent for the 12 months ending March 2004.
"Since at least 2000, drug prices have risen steadily. The first three months of 2004 looks like more of the same," said AARP Board Member Doug Holbrook. "This is an outrage."
The report, "Trends in Manufacturer Prices of Brand Name Prescription Drugs Used by Older Americans-First Quarter 2004 Update", is the first quarterly update in an ongoing study of changes in prices that drug manufacturers charge wholesalers. A baseline study published in May 2004 looked at prices between 2000 and 2003 and found manufacturers' wholesale prices, on average, had steadily increased and, for each year, exceeded the rate of general inflation. Researchers are focusing on manufacturers' price to wholesalers because it is the most substantial component of a prescription drug's retail price.
The study, published by the AARP Public Policy Institute (PPI), found that 29 percent (58) of the drugs studied had increases in the first quarter (i.e., the period from December 31, 2003 to March 31, 2004) of more than 5 percent, or more than four times the rate of inflation for the same period. First quarter increases of more than 7.5 percent were found in almost 11 percent (21) of the drugs. Of the 25 brand name drugs with the greatest sales in 2003, nearly two-thirds (16) had price increases in the first quarter of 2004. Plavix 75 mg, which is third in sales among the drugs studied, had the highest percentage increase among the top 25 drugs, with 7.9 percent in the first quarter. The PPI study was coauthored by AARP's David Gross and Susan Raetzman with Professor Stephen Schondelmeyer of the University of Minnesota.
