Tramadol and tilidine (in combination with naloxone) are used as weak opioid analgesics in Germany. Tramadol is not scheduled in the German Narcotic Drugs Act. Tilidine is scheduled, whereas Tilidine in fixed combinations with naloxone is exempt from some of the provisions of the Narcotic Drugs Act. Recent reports on misuse of both substances led to an evaluation of their potential for misuse, abuse, and dependency by the expert advisory committee established by the German Federal Government, resident at the Federal Institute for Drugs and Medical Devices. ⋯ In conclusion, the subcommittee of the expert advisory committee found a low potential for misuse, abuse, and dependency for tramadol, and a low prevalence in clinical practice. Considerable less information is available for the combination of tilidine and naloxone. However, the cumulation of evidence indicated a higher risk of misuse, abuse, and dependency for tilidine/naloxone solution, but not for slow-release tablets.
