Desocodeine

Desocodeine is a potent semi-synthetic opioid which is the penultimate intermediate in the manufacture of desomorphine from codeine. Desocodeine is a potent analgesic, being as potent as morphine. It is partially metabolized into desomorphine, among others, after parenteral and oral administration.
Since 1936, desocodeine has been classified in the US as a Schedule I controlled substance under the Controlled Substances Act, indicating that the FDA has determined that there are no legal medicinal uses for it.
In Canada, desocodeine is classified as a Schedule I drug under the Controlled Drugs and Substances Act.
