Abstract
OBJECTIVE Olanzapine is widely prescribed for patients with mental disorders; however, it may induce metabolic dysfunction. Metformin is an efficient adjuvant for preventing olanzapine-induced metabolic dysfunction in clinical practice. Although the mechanism of how metformin prevents this metabolic dysfunction remains unknown, changes in the gut-liver axis are considered a potential explanation. METHODS Forty-eight male rats were gavaged with olanzapine and/or metformin for 35 consecutive days. Body weight, food intake, and water intake were measured daily. Histopathological and biochemical tests were performed to evaluate the metabolic dysfunction. The 16S rRNA obtained from fecal bacterial DNA was assessed. RESULTS Olanzapine treatment increased the body weight, blood glucose and triglyceride levels, and the number of adipocytes in the liver. While coadministration of metformin, there was a dose-dependent reverse of the abnormal changes induced by olanzapine treatment. Both olanzapine and metformin treatments altered the composition of the gut microbiota. Bacteroides acidifaciens and Lactobacillus gasseri were possibly played a positive role in metformin-mediated olanzapine-induced metabolic dysfunction prevention. CONCLUSION Metformin prevented olanzapine-induced metabolic dysfunction and regulated the gut microbiota in a dose-dependent manner.
