Abstract
We conducted exploratory analyses of the data from a multinational, randomised study to identify factors associated with weight change after 16 weeks of treatment with standard olanzapine tablets (SOT) or sublingual orally disintegrating olanzapine (ODO). One hundred and forty nine outpatients who gained weight during prior SOT therapy were enrolled into the study and treated with ODO (N = 84) or SOT (N = 65). Exploratory analyses were conducted with the subset of compliant patients (ODO: n = 60; SOT: n = 47). The decrease in the rate of weight gain at the end of study therapy (change from baseline) was greater in the ODO group than the SOT group (-0.59 kg/week vs. -0.38 kg/week, p = 0.0246). Age was negatively associated with weight change (p = 0.0203) in both treatment groups combined: patients gained 0.7 kg less for every 10 years of age. The least squares mean weight gain was lower with ODO than SOT in male patients (0.35 kg vs. 3.04 kg, p = 0.061), but not female patients and in American patients (0.55 kg vs. 6.21 kg, p < 0.0001), but not Canadian or Mexican patients. Although not conclusive, these data suggest that ODO may be a reasonable treatment option for some patients who gain weight with SOT. Further research is required to confirm these findings
