Aripiprazole in the pharmacotherapy of Gilles de la Tourette syndrome in adult patients.
Despite the ongoing development of neuroleptics, typical or first-generation neuroleptics are still considered as the first choice in the treatment of Gilles de la Tourette syndrome (GTS). In many European countries, tiapride is the first line of treatment favoured in most cases, while risperidone, pimozide and haloperidol are listed as second choice. Unfortunately, antipsychotics often show tachyphylactic effects in the treatment of GTS so that a switch to another neuroleptic agent becomes inevitable. Thus it is important to ensure a wide selection of different drugs is available. Another promising candidate in the treatment of tics may be aripiprazole, a D(2)-receptor partial agonist. We present the retrospective analysis of 10 clinical cases of adult patients from the tic clinics in Aachen (Germany) and Zurich (Switzerland) who were treated with aripiprazole. Tics and disturbances were assessed using the Yale Global Tic Severity Scale (YGTSS). All YGTSS-subscores, with the exception of the complexity of vocal tics, improved significantly. The data includes three cases with long-term intake for at least 18 months. During this period, no tachyphylactic effect was visible. A double-blind trial against placebo or other neuroleptics is advisable to verify the efficacy of aripiprazole in the pharmacotherapy of GTS.
