Patent

CA 2502787

Certain atypical antipsychotic medications (particularly clozapine) or combinations of medications are useful to treat alcohol or other substance abuse, particularly in the general (non-schizophrenic) population. Generally stated, one aspect of the invention features a method of treating a patient suffering from alcohol or other substance abuse by administering to the patient medication effective to rectify an abuse-associated dysfunction in the DA-mediated brain reward circuit. A second aspect of the invention features administering medication that strongly antagonizes .alpha.2 andrenergic receptors and weakly antagonizes dopamine D2 receptors. Preferably, the ratio of .alpha.2 receptor blockade to D2o receptor blockade is similar to that of clozapine. The medication may be a single compound (such as clozapine or risperidone), or it may include two or more compounds which together achieve the specified function. For example, the medication may include a first component which weakly blocks the D2 receptor (such as clozapine, quetiapine or ziprasidone or a low dose of another anti-psychotic that is a more potent D2 blocker) and a5 second component (such as clozapine, risperidone or idazoxan) which strongly blocks .alpha.2 receptors, particularly the .alpha.2C receptor. Cocktails of the two components are also disclosed.

Certains médicaments antipsychotiques atypiques (en particulier la clozapine) ou combinaisons de médicaments sont utiles pour le traitement de l'abus d'alcool ou d'autres substances, en particulier dans l'ensemble de la population (non schizophrène). D'une manière générale, selon un aspect, l'invention concerne un procédé de traitement correspondant, par administration de médicament efficace pour rectifier un dysfonctionnement lié à cet abus dans la voie de récompense du cerveau dont la médiation est assuré par la dopamine. Selon un second aspect, on administre un médicament à forte action antagoniste vis-à-vis des récepteurs .alpha.2-adrénergiques et à faible action antagoniste vis-à-vis des récepteurs D2 de la dopamine. De préférence, le rapport de blocage entre les deux récepteurs est similaire à celui de la clozapine. Le médicament peut être un composé simple (du type clozapine ou rispéridone), ou bien il peut comprendre un premier élément qui bloque faiblement le récepteur D2 (du type clozapine, quétiapine ou ziprasidone, ou une faible dose d'autre antipsychotique qui a une action antagoniste plus forte vis-à-vis du récepteur D2) et un second élément (du type clozapine, rispéridone ou idazoxane) qui a une forte action antagoniste vis-à-vis des récepteurs .alpha.2, en particulier le récepteur .alpha.2C. L'invention concerne également des combinaisons de ces deux éléments.
