BACKGROUND: The risks of antipsychotic drugs on metabolic syndrome (MS) present many challenges for psychiatrists.
AIM: To evaluate the effectiveness and influences on glucolipid metabolism in patients with schizophrenia and metabolic disorders switched from clozapine to ziprasidone.
PATIENTS AND METHODS: Schizophrenic patients with metabolic syndrome who had been treated with clozapine for ≥ 2 years were enrolled in the open-label study. All the patients were switched to ziprasidone from clozapine and followed up for 24-week. The primary endpoints included body mass index (BMI), fasting glucose (FG), triglycerides (TG), HDL cholesterol (HDL-c) and systolic pressure (SP)/diastolic pressure (DP). Secondary endpoints included scores on the Positive and Negative Syndrome Scale (PANSS) and treatment emergent symptom scale (TESS).
RESULTS: A total of 213 cases satisfied the inclusion and exclusion criteria, but only 194 cases eventually completed the 24-week follow-up and were divided into ziprasidone group (n=68, complete substitution) and combined treatment group (n=126, partial substitution). In the ziprasidone group, TG at 4th and 24th week, BMI and HDL-c at 24th week were significantly improved (p < 0.05), while cognitive scores and total score of the PANSS at 4th and 24th week, negative factor, the factor of anxiety and depression at 24th week were significantly lower than those at the baseline (p < 0.05); In the combined group, cognitive factor scores (4 weekend, 24 weekends) and total score of PANSS (24 weeks) was significantly lower than baseline (p < 0.05). There was no significant difference in the TESS score (p > 0.05).
CONCLUSIONS: Ziprasidone completely or partially substituting clozapine can improve both glucolipid metabolism disorders, and cognitive disorders and affective disorders of schizophrenia.Free PDF Download
