TY - JOUR T1 - CLozapine plus lamotrigine in treatment-resistant schizophrenia AU - Dursun SM, McIntosh D, Milliken H Y1 - 1999/10/01 N1 - 10.1001/archpsyc.56.10.950 JO - Archives of General Psychiatry SP - 950 EP - 950 VL - 56 IS - 10 N2 - Glutamate is an excitatory neurotransmitter, and clozapine acts as a glutamate antagonist. Lamotrigine, an anticonvulsant and mood stabilizer, inhibits excessive release of glutamate.2 Both drugs block the psychotomimetic effects of phencyclidine (PCP). These schizophrenia-like symptoms are attributed to PCP's activity at the NMDA (glutamate) receptor. The biochemical significance of these glutamate interactions in schizophrenia remains unclear and is hotly debated. There is evidence to suggest that there is abnormal glutamatergic binding in the areas of the brain associated with psychotic symptoms in patients with schizophrenia.3 SN - 0003-990X M3 - doi: 10.1001/archpsyc.56.10.950 UR - http://dx.doi.org/10.1001/archpsyc.56.10.950 ER -
