非定型抗精神病薬はせん妄の治療に広く用いられている。しかしながら,せん妄に対するaripiprazoleの報告は少ない。今回我々は,aripiprazoleのせん妄に対する有効性と安全性について検討したので報告する。対象はICD-10でせん妄と診断された患者17例で,有効性の判定には日本語版せん妄評価尺度98年改訂版の重症度得点を使用した。13例において有効性が認められ,有効率は76.5%であった。初回投与量は5.8±0.8mg/日,最大投与量は8.1±3.3mg/日,効果が最大に達するまでの日数は5.4±4.6日であった。ふらつきが3例(17.6%),眠気が2例(11.8%)に認められたが,重大な有害事象は認められなかった。以上から,aripiprazoleのせん妄に対する有効性と安全性が示唆された。今後さらなる研究が望まれる。
Atypical antipsychotics have been widely used for the treatment of delirium. However, there are only few reports on clinical trials of aripiprazole for its use in the treatment of delirium. In the present study, we describe the efficacy and safety of aripiprazole in the patients with delirium. Seventeen patients with ICD-10 delirium were administered open-label aripiprazole. To evaluate the efficacy of aripiprazole, the scores of 13 severity items of the Japanese version of the Delirium Rating Scale-Revised-98 were assessed. Aripiprazole was effective in 76.5% (13/17) of the patients. The initial dose of aripiprazole was 5.8±0.8 mg/day, and the maximum dose was 8.1±3.3mg/day. The maximum treatment response was achieved at 5.4±4.6days. Lightheadedness (17.6%) and somnolence (11.8%) were observed;however, there were no serious adverse effects. These results suggest the efficacy and safety of using aripiprazole in the treatment of delirium. To verify these preliminary findings, further controlled comparison studies are needed.
