Drotebanol has powerful antitussive (cough suppressant) effects, and is around 10x more potent than codeine in producing this effect. It also has analgesic effects several times stronger than codeine, but weaker than morphine.^[2] In animal studies it was found to be moderately addictive and produced limited physical dependence, but not as severe as that seen with morphine or pethidine.^[3] It was previously marketed for human use under the brand name Metebanyl, although it is now no longer used in medicine.

It is currently a Schedule I Narcotic controlled substance in the United States with a DEA ACSCN of 9335 and an annual aggregate manufacturing quota of zero.
