Actual (reported)One double-blind, randomized, placebo-controlled trial is designed to examine whether berberine added to current antipsychotic drugs could produce significantly greater efficacy in reducing atypical antipsychotic-induced metabolic syndrome. To achieve this objective, 120 patients with schizophrenia spectrum disorders (SSD) who have developed metabolic syndrome will be recruited and randomly assigned to receive additional treatment with placebo (n = 60) or berberine (n = 60, 0.6 g/day, 0.3 g, b.i.d.) for 12 weeks. The primary outcome is changes in net weight gain; other outcomes include body mass index (BMI), waist circumference (WC), blood pressure, triglycerides (TG), total cholesterol, high-density lipoprotein (HDL), and low-density lipoprotein (LDL), fasting glucose, glycated haemoglobin (HbA1c).

Antipsychotic agents prescribed at the discretion of the patients' psychiatrists with respect to patients' conditions. Concomitant use of other psychotropic drugs, including antidepressants, anxiolytics, and mood stabilizers for mood disorders, benzodiazepines and non-benzodiazepines for insomnia, and anticholinergics for extrapyramidal symptoms, was allowed as usual. For those who were under anti-hyperlipidemic, antihypertensive and anti-diabetic treatment, they were allowed to continue their current medications throughout the study.
