ABSTRACT
AIM:
We investigated the clinical efficacy and safety of switching to paliperidone (PAL) in elderly schizophrenia patients receiving risperidone.METHODS:
The subjects were 27 inpatients who had been diagnosed with schizophrenia according to the DSM-IV. The patient's clinical symptoms were assessed using the Positive and Negative Syndrome Scale and the Clinical Global Impression-Severity of Illness Scale, and their safety was assessed using the Drug-induced Extrapyramidal Symptoms Scale, bodyweight, body mass index, and laboratory tests. We also investigated patient satisfaction using the Drug Attitude Inventory, a subjective outcome measure.RESULTS:
No significant differences in clinical symptom improvement efficacy were seen between the PAL-switching group and the control group. The mean changes from baseline on the Drug-induced Extrapyramidal Symptoms Scale total score, Drug Attitude Inventory score, and prolactin level were significantly greater in the PAL-switching group than in the control group. Furthermore, patients with PAL needed less biperiden, even though they had similar risperidone-equivalent daily dosages to the control group.CONCLUSIONS:
The results of this study suggest that switching elderly patients from risperidone to PAL may result in superior safety and patient satisfaction, and may also make it possible to reduce the dosage of biperiden.
