Between 1994 and 2004, real (inflation-adjusted) spending on prescription drugs rose at an average annual rate of 11.1 percent, compared with 3.5 percent for hospital care and 4.3 percent for physicians services. More recently, however, that growth has slowed: From 2004 to 2007, drug expenditures grew
by an average of just 3.2 percent per year, slightly less than the rate of growth in overall health care spending. As a fraction of total spending on health care, spending on prescription drugs rose from 6 percent in 1994 to around 11 percent in 2004, where it has remained.”
