Description
商品名Abilify(登録商標)で販売されているアリピプラゾールは、ドーパミンD2およびセロトニン5-HT1A受容体アゴニストで、セロトニン5-HT2A受容体のアンタゴニストである。アリピプラゾールは、精神分裂症ならびに他の精神障害および中枢神経系障害の治療に用いられる。例えば、特許文献1参照。Abilifyは経口投与用錠剤として現在販売されている。しかし、経口抗精神病薬では、患者コンプライアンスが低いことが報告されている。従って、アリピプラゾールなどの抗精神病薬の送達方法を改良し、それにより患者コンプライアンスを改善し、活性薬剤の薬理学的プロフィールを最大限に活用する必要がある。

本発明は、一部、ボーラス注射で投与されるアリピプラゾールおよび担体を含有する医薬組成物が、活性薬剤を含むポリラクチド−コ−グリコライドミクロスフェア製剤の注射により得られるのと同様の長期放出プロフィールを生じたという発見に関する。この驚くべき結果は、高分子ミクロスフェアの製造に係わる複雑さと費用を伴うことなく、薬理的に有益な長期放出製剤が得られ得ることを示唆している。
本発明は、粘度増強剤を任意に含有する注射用ビヒクル中にアリピプラゾールを含む混合物を含有するアリピプラゾールの長期放出のための注射可能な組成物に関する。アリピプラゾールは、少なくとも約10 mg/ml、好ましくは少なくとも約20 mg/mlまたは少なくとも約30 mg/mlの量で存在し得る。本発明はまた、注射用ビヒクル中に少なくとも約50 mgのアリピプラゾールを含む混合物を投与することを含む、長期放出性で注射可能な組成物にて個体にアリピプラゾールを提供する方法に関する。
