Montreal Gazette - Montreal team learns why painkillers wear off


A team of Montreal researchers has solved the mystery of why the soothing effects of morphine and other similar drugs often wear off within hours, raising hopes of a new generation of longer-lasting painkillers to treat chronic conditions such as arthritis and nerve pain.

Scientists in the department of pharmacology at the Université de Montréal as well as the Alan Edwards Centre for Research Pain at McGill University were also involved in the study.
