Scientists are testing an experimental medicine that’s designed to have the painkilling power of morphine without some of the dangerous side effects that can lead to overdose deaths.
The compound is so new it doesn’t have a name, just a number. It’s only been tested in mice, and it needs years of additional animal studies before researchers can even start trials to see if it works safely in humans.
But initial results in mice suggest the new drug might be less addictive than morphine and other opiate painkillers and avoid a side effect known as respiratory depression that results in overdose deaths, scientists say.
