Weight gain and the corresponding metabolic syndrome represent a "deal killer" with regard to the treatment of most patients. However, one recent small study may be highly relevant to this discussion. De Haan et al. investigated the relative effects of standard olanzapine tablets to the orally-disintegrating form (Zydis) in adolescents and young adults who had gained weight with olanzapine. The group randomly assigned 18 patients to continuation olanzapine tablets or Zydis for a 16-week period. The Zydis-treated patients lost an average of 6.6 kg. while the continuation regular olanzapine group gained 3.7 kg. Although small, this study suggests a potential solution to the weight-gain problem associated with olanzapine.
