Metformin plus sibutramine for olanzapine-associated weight gain and metabolic dysfunction in schizophrenia: a 12-week double-blind, placebo-controlled pilot study

Psychiatry Res. 2008 May 30;159(1-2):250-3. doi: 10.1016/j.psychres.2008.01.011. Epub 2008 Apr 18.

Abstract

Metformin (850-1700 mg) plus sibutramine (10-20 mg, n=13) or placebo (n=15) was administered for 12 weeks in olanzapine-treated chronic schizophrenia patients. Weight loss was similar in both groups: -2.8+/-3.2 kg vs. -1.4+/-2.6 kg. Except for preventing a triglyceride increase, the drug combination lacked efficacy for metabolic control in this clinical population.
