Does a GLP-1 Receptor Agonist Change Glucose Tolerance in Antipsychotic-treated Patients?

Summary

Metabolic disturbances, obesity and life-shortening cardiovascular morbidity are major clinical problems among antipsychotic-treated patients. Especially two of the most efficacious antipsychotics, clozapine and olanzapine, cause weight gain and metabolic disturbances and can rarely be replaced by other drugs due to the effectiveness of the compounds. Glucagon-like peptide 1 (GLP-1) has improved glycemic control among patients with type 2 diabetes. The study will investigate whether the beneficial effects of GLP-1 analogues on glycemic control in type 2 diabetic patients, can be extended to a population of non-diabetic, dysglycemic psychiatric patients, receiving antipsychotic medical treatment.
