Managed detoxification is a first and necessary step prior to treatment and rehabilitation. Detoxification can be a major obstacle for some patients, and the availability of managed and safe withdrawal is a prerequisite for long-term treatment.

In our clinical practice we have felt the need for a standardised and safe detoxification treatment regimen for our opioid addicts, as dependence on multiple drugs is so common.


  1. To assess whether a novel standardised treatment regimen - Buprenorphine (BPN) combined with Valproate (VPA) - will result in fewer withdrawal symptoms during detoxification of opiate–polydrug users than the existing treatment regimen, i.e. Clonidine (CLN) combined with Carbamazepine (CBZ).
  2. To determine whether there are differences in treatment retention between the BPN/VPA and the CLN/CBZ groups.
  3. To assess differences in clinical side-effects and biochemical interactions between the two treatment regimens.
