Celecoxib augmentation of continuously ill patients with schizophrenia.

BACKGROUND: Previous reports have demonstrated a beneficial effect of celecoxib adjunctive therapy for patients with an acute exacerbation of schizophrenia. We investigated the effects of celecoxib augmentation of atypical antipsychotic medications for continuously symptomatic outpatient subjects with schizophrenia to further extend these findings. We hypothesized that celecoxib augmentation therapy would improve psychopathology ratings compared with placebo.
METHODS: Thirty-eight symptomatic outpatient subjects meeting DSM-IV criteria for schizophrenia and on a stable dose of an atypical antipsychotic medication for at least three months were randomized to receive 8 weeks of double blind placebo or celecoxib (400 mg/day) augmentation. Measures of psychopathology, functional disability, and extrapyramidal side effects were performed throughout the study.
RESULTS: The treatment cohorts did not differ on any of the clinical outcome measures.
CONCLUSIONS: Celecoxib augmentation of continuously ill outpatient subjects with schizophrenia did not improve clinical symptoms or measures of disability.
