A change in the formula of the frequently abused prescription painkiller OxyContin has many abusers switching to a drug that is potentially more dangerous, according to researchers at Washington University School of Medicine in St. Louis.
The formula change makes inhaling or injecting the opioid drug more difficult, so many users are switching to heroin, the scientists report in the July 12 issue of the New England Journal of Medicine.
For nearly three years, the investigators have been collecting information from patients entering treatment for drug abuse. More than 2,500 patients from 150 treatment centers in 39 states have answered survey questions about their drug use with a particular focus on the reformulation of OxyContin.
