Uncovering how morphine increases pain in some people

2013-01-12

Recent discoveries published in Nature Neuroscience "identifies a molecular pathway by which morphine can increase pain, and suggests potential new ways to make morphine effective for more patients" says Yves De Koninck, senior author of the paper. 

The research not only identifies a target pathway to suppress morphine-induced pain but teases apart the pain hypersensitivity caused by morphine from tolerance to morphine, two phenomena previously considered to be caused by the same mechanisms.

"When morphine doesn't reduce pain adequately the tendency is to increase the dosage...
