Alletorphine (R & S 218-M) is a potent analgesic said to have a reduced respiratory depressant action. It was isolated by Bentley and Hardy (1967) while they were examining a series of derivatives of tetrahydrothebaine of which the potent analgesic etorphine (propylorvinolhydrochloride: M99 Reckitt) is a member. R&S 218-M bears the same relationship to etorphine as does nalorphine to morphine. It has been the subject of experiments in animals and human volunteers.

The analgesic effects of Alletorphine (R & S 218-M), administered in doses of 0.56 mg/70 kg and 0.35 mg/70 kg, were compared with those of morphine sulphate 10.5 mg/70 kg for the relief of abdominal pain following surgery in healthy adults. The drugs were given as the first potent analgesic after operation. R & S 218-M 0.56 mg/70 kg was as effective as morphine sulfate 10.5 mg/70 kg, while R & S 218-M 0.35 mg/70 kg was inferior.
