Desomorphine[note 1] is a semi-synthetic opioid commercialized by Roche, with powerful, fast-acting effects, such as sedation and analgesia.[3][4][5][6] It was first discovered and patented in Germany by a German team working for Knoll in 1920[7] but was not generally recognized. It was later synthesized in 1932 by American chemist Lyndon Frederick Small. Small also successfully patented it in 1934 in the United States.[8] Desomorphine was used in Germany, Austria, and Switzerland under the brand name Permonid[9] and was described as having a fast onset and a short duration of action, with relatively little nausea compared to equivalent doses of morphine. Dose for dose it is roughly ten times more potent than morphine, with 1 mg desomorphine being equivalent 10 mg morphine, via the intravenous (IV) or intramuscular (IM) routes.[10]

Desomorphine is a morphine analogue where the 6-hydroxyl group and the 7,8 double bond have been reduced.[8] The traditional synthesis of desomorphine starts from α-chlorocodide, which is itself obtained by treating codeine with thionyl chloride. By catalytic reduction, α-chlorocodide gives dihydrodesoxycodeine, which yields desomorphine on demethylation.[11][12]

A desomorphine product, usually based on codeine, has been developed as a recreational drug.[13] The product in question is typically a highly impure variant of desomorphine. The scaly sores and necrosis that develop around the injection site has prompted the name krokodil (Russian for crocodile).
