Effect of liraglutide 3.0mg treatment on weight reduction in obese antipsychotic-treated patients

초록

Background: Patients treated with antipsychotics experience significant weight gain and accompanying metabolic disorders. We investigated the efficacy of liraglutide 3.0 mg in reducing the weight of antipsychotic-treated obese patients. Method: We retrospectively reviewed 16 obese patients with schizophrenia or bipolar disorder who were treated with 3.0 mg of liraglutide each. During the 16 weeks of treatment, changes in body weight and Clinical Global Impression-Severity scale (CGI-S) were analyzed. The participants were divided into responders (lost at least 5% of body weight) and non-responders for analysis. Results: Treatment with liraglutide 3.0 mg significantly decreased body weight (estimated marginal mean, 93.2 kg at baseline and 88.9 kg at 16 weeks; p < 0.001) as well as waist circumference, BMI and plasma glucose levels. Six of 16 patients (37.5%) complained of a modest degree of nausea. Six of the 12 subjects (50%) completing 16 weeks of treatment were responders. There were no significant differences in baseline characteristics between responders and non-responders. There was no worsening of CGI-S scores. Conclusion: Liraglutide 3.0 mg significantly decreased body weight in obese patients treated with antipsychotics without altering the status of psychiatric diseases. A randomized controlled study is required to corroborate the results of this study.
