Anidoxime
Anidoxime was an experimental drug that had been evaluated for use as an oral analgesic.
The name is an eponym of an anisdine group and an oxime. The analgesic properties are reportedly equipotent to or greater than morphine but the physical dependence liability may be less.
In rats, the major metabolic pathway is hydrolysis of the carbamoyl group followed by decarboxylation.
