Selective serotonin reuptake inhibitor augmentation in the treatment of negative symptoms of schizophrenia.
The treatment of negative symptoms of schizophrenia presents a major clinical challenge. This review examines the evidence pertaining to the efficacy, tolerability and safety of adding selective serotonin reuptake inhibitors (SSRIs) to antipsychotic agents in the treatment of negative symptoms in schizophrenia. Important methodological issues such as differentiating primary and secondary negative symptoms are discussed. The balance of available evidence indicates that at least some SSRIs, fluvoxamine and fluoxetine, can ameliorate primary negative symptoms in chronic schizophrenia patients who are treated with typical antipsychotics. The combination is safe and well tolerated although, as antipsychotic drug concentrations may be elevated, attention to dose and drug monitoring should be considered as appropriate. The effect of SSRI augmentation of atypical antipsychotics requires further study. Combination with clozapine may require particular caution because of potential toxicity if serum clozapine levels rise steeply. SSRI augmentation may be a useful addition to the treatment of schizophrenia.
