CA 2547652

The present invention provides methods of treating cocaine-induced pyschosis by administering an atypical antipsychotic compound in an amount sufficient to increase serotonin concentration in the nucleus accumbens of a mammal. According to the invention, atypical antipsychotic compounds include, without limitation, clozapine, risperidone, olanzepine, quetiapine, ziprasidone, sertindole, ketanserin, aripiprazole, and haloperidol, flupenthixol, thiroridazine, loxapine, fluspirilense, and sulpliride. The invention further provides methods for microvoltammetric imaging of changes in neurotransmitter concentrations in vivo and in real time comprising contacting the cell, cells, tissue, tissues, or organ of interest with a BRODERICK PROBE® sensor, applying a potential to said BRODERICK PROBE® sensor, and monitoring a temporally and spacially resolved recording using neuromolecular imaging (NMI) and electrochemical circuits such as, for example, voltammetry. In one embodiment of the invention, neuromolecular imaging may be performed before, during or after cocaine administration and/or cocaine-induced psychosis.

L'invention concerne des méthodes permettant de traiter une psychose induite par la cocaïne par administration d'un composé atypique antipsychotique en quantité suffisante pour augmenter la concentration de sérotonine dans le noyau accumbens d'un mammifère. Selon l'invention, ledit composé atypique antipsychotique comprend, sans limitation, la clozapine, la rispéridone, l'olanzépine, la quétiapine, la ziprasidone, le sertindole, la kétansérine, l'aripiprazole, l'halopéridol, le flupenthixol, la thiroridazine, la loxapine, le fluspirilense et le sulpliride. L'invention concerne également des méthodes permettant de former des images microvoltamétriques des changements de concentration des neurotransmetteurs in vivo et en temps réel, qui consistent à mettre en contact la ou les cellule(s), le ou les tissu(s) ou un organe d'intérêt avec un capteur de sonde Broderick, à appliquer un potentiel sur ledit capteur de sonde Broderick et à surveiller un enregistrement temporellement et spatialement résolu à l'aide d'une imagerie neuromoléculaire (NMI) et de circuits électrochimiques, par exemple, par voltamétrie. Dans un mode de réalisation de l'invention, l'imagerie neuromoléculaire peut être exécutée avant, pendant ou après l'administration de cocaïne et/ou avant, pendant ou après une psychose induite par la cocaïne.
