Lefetamine (Santenol) is a drug which is a stimulant and also an analgesic with effects comparable to codeine.

Lefetamine-related 1,2-diphenylethylamines were invented in the 1940s and showed weak analgesic activity.[1]

It was investigated in Japan in 1950s.[2] The l-isomere showed weak analgetic action comparable to codeine and antitussive action far weaker than codeine. The d-isomer showed no such activity but caused seizures in rats.[3][4]

It was abused in Japan during the 1950s. In a small study in 1989 it showed some effect against opioid withdrawal symptoms without causing withdrawal symptoms itself. It was concluded that it may be an opioid partial agonist.[5]

It has been abused in Europe, in 1989 a small study of 15 abusers and some volunteers found, that it had some partial similarity to opioids, that it produced withdrawal symptoms and had dependence and abuse potential to a certain degree.[6]

In a small study in 1994 it was compared to clonidine and buprenorphine for the detoxification of methadone patients and found to be inferior to both for this purpose.[7]


Some related pyrrylphenylethanones had analgetic activity comparable to morphine.[8] Some pyrrole analogues were reported to have analgetic effects comparable to lefetamine and being devoid of neurotoxic properties.[9]
