Brief Summary
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).

Study Arms (2)
Berberine
ACTIVE COMPARATORPatients will receive berberine pills in additional to current atypical antipsychotic agents
Placebo
PLACEBO COMPARATORPatients will receive placebos pills in additional to current atypical antipsychotic agents
Interventions
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.

- a primary diagnosis of SSD, including schizophrenia, schizoaffective disorder, schizophreniform disorder, and psychotic disorder not otherwise specified according to the Classification of Mental and Behavior Disorders (10th version);
- have been under atypical antipsychotic treatment for at least 3 months and current conditions are stable, indicated by no difficulty to communicate with investigators and give informed consent; and
- have developed metabolic syndrome according to the International Diabetes Federation criteria for metabolic syndrome in Asian/Chinese population.
You may not qualify if:
- serious comorbid gastrointestinal or other unstable medical conditions;
- have suicidal ideas or attempts or aggressive behavior;
