Results: Sixty patients who completed 2 weeks of risperidone treatment were divided into 33 early responders (RIS-ER) and 27 ENRs (RIS+OLZ, n=14; RIS-OLZ, n=13). Although time to treatment discontinuation for any cause was significantly shorter in RIS+OLZ group (54.1 days [95% confidence interval, 41.3-67.0]) than in RIS-ER group (68.7 [61.2-76.2]; P=0.050), it was not significantly shorter in RIS-OLZ group (58.5 [43.1-73.9]) than in RIS-ER group (P=0.19). Sixty patients who completed 2 weeks of olanzapine treatment were divided into 36 early responders (OLZ-ER) and 24 ENRs (OLZ+RIS, n=11; OLZ-RIS, n=13). Although time to treatment discontinuation for any cause was significantly shorter in OLZ-RIS group (56.1 days [40.7-71.5]) than in OLZ-ER group (74.9 [68.5-81.3]; P=0.008), it was not significantly shorter in OLZ+RIS group (64.6 [49.6-79.6]) than in OLZ-ER group (P=0.20).
Conclusion: Despite the lack of pharmacokinetic investigation of dose adequacy in this study, it is possible that switching to olanzapine among ENRs to risperidone might have a small advantage over augmentation with olanzapine, while augmentation with risperidone might have a small advantage over switching to risperidone among ENRs to olanzapine. Further research is required before it would be appropriate to modify routine practice in the direction of these findings.
