[New developments in the pharmacotherapy of cocaine dependence].

New possibilities with medications for the treatment of cocaine dependence have begun to emerge. For example, in a randomised controlled study, disulfiram succeeded for the first time in significantly reducing cocaine consumption. In October 2003, a phase IIb study was started in the USA testing active immunisation against cocaine dependence. There is also an ongoing study in Switzerland testing methylphenidate treatment in combination with cognitive behavioural therapy. Pilot studies indicate that vigabatrin, selegiline, and topiramate are promising candidates for further clinical substance testing.
