Metformin Alleviates Abnormal Glucose Metabolism Induced by Statins in Schizophrenia Patients

Metformin Alleviates Abnormal Glucose Metabolism Induced by Statins in Schizophrenia Patients: A Randomized, Double-Blind, Placebo-Controlled Multicenter Clinical Study

Source: ClinicalTrials.gov · Last updated 3 Aug 2026

Brief summary (registry, in English)

Schizophrenia is a severe mental illness associated with significant morbidity and disability. Patients often experience metabolic side effects from antipsychotic medications, including weight gain and dyslipidemia. Statins, commonly used to manage dyslipidemia, can lower cholesterol levels but may increase the risk of new-onset diabetes. This study aims to investigate how atorvastatin affects glucose metabolism in schizophrenia patients and assess whether metformin can help improve these metabolic issues. The investigators will include 200 patients with dyslipidemia from the Second Xiangya Hospital and other sites, randomly assigning them to receive either atorvastatin with metformin or atorvastatin with placebo over six months. Key goals include evaluating the impact of atorvastatin on insulin resistance and blood glucose levels and determining the effectiveness of metformin in mitigating glucose metabolism abnormalities while managing lipid levels. Understanding these interactions will help improve treatment strategies for schizophrenia patients, potentially lowering their risk of cardiovascular diseases and diabetes and enhancing overall health outcomes.

Prior treatment

  • Patients with a prior diagnosis of diabetes or complications such as diabetic ketoacidosis;

Lab values

  • Patients with liver or kidney dysfunction, indicated by aspartate aminotransferase (AST), alanine aminotransferase (ALT), or gamma-glutamyl transferase (GGT) levels exceeding twice the normal limits, and/or creatinine levels exceeding 1.2 times the upper limit of the reference range or greater than 2 mg/dL, or deemed by the investigator to have liver and/or kidney impairment that warrants exclusion from the study;
  • Patients with severe gastrointestinal, respiratory, endocrine, hematologic diseases, or metabolic absorption disorders: including but not limited to poorly controlled diabetes, severe acute systemic infections or immunological diseases, ischemic heart disease, cerebrovascular accidents within the past year, history of prolonged QT interval, active hepatitis B virus, chronic active hepatitis C, and malabsorption syndromes;
  • Clinically significant abnormal ECG findings at screening that the investigator deems unsuitable for inclusion, such as male QTc interval \> 470 ms, female QTc interval \> 480 ms;

Other

  • Pregnant or nursing women.
