Description

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.

Sample Use Guides

In Vivo Use Guide

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.
