According to a recent AARP study, brand-name prescription drug prices have climbed at twice the rate of inflation during the 12 months ending in June 2005 (6.1% vs. 3.0%). The good news here (if there is any) is that this increase was slightly below the 7.1% and 7.0% increases in the previous two years. The drug that experienced the largest price increase was the emphysema drug Atrovent, which soared 18% (from $2.12/day to $2.51/day). The sleep aid Ambien was a close second, increasing 14% (from $2.19/day to $2.50/day). In contrast, generic drug prices are reported to have risen just 1% over the same time period. This is just further evidence that you should be using generic drugs whenever possible.
