明 細 書 自閉症治療剤 技術分野  Description Autism agent Technical field
本発明は、 小児の自閉症の治療に有用な治療剤に関する。 背景技術  The present invention relates to a therapeutic agent useful for treating autism in children. Background art
小児自閉症 (Chi ldhood aut ism) は、 3歳以前の小児に現れる発達の 異常および または障害の存在、 並びに、 相互的な社会的関係、 コミュ 二ケーシヨン、 限局した反復的な行動の 3つの領域全てにみられる特徴 的な型の機能の異常によって定義される広汎性発達障害 (Pervasi ve De velopmental Disorders : 相互的な社会関係とコミュニケーションのパ ターンにおける質的障害、 および限局した常同的で反復的な関心と活動 の幅によって特徴付けられる一群の障害 )である。  Childhood autism is the presence of developmental abnormalities and / or disabilities that appear in children younger than three years of age, as well as three aspects of reciprocal social relationships, communication, and limited repetitive behavior. Pervasive Developmental Disorders: Qualitative impairments in patterns of mutual social relations and communication, and localized stereotypes, defined by characteristic types of functional abnormalities in all areas. A group of obstacles characterized by repetitive interests and a range of activities.
小児自閉症の患児では、 てんかん発作が 15〜30% に出現し、 脳波異常 が 30〜70% に存在することが知られている。 これらの発現率は一般の小 児に比べて有意に高いことから、 小児自閉症の原因が脳障害である可能 性が示唆されている。 しかしながら、 脳障害の部位を特定し得ることは 極めて稀であることから、 一般にはシステムとしての中枢神経機能の障 害と考えられている。  It is known that epileptic seizures occur in 15 to 30% of children with autism, and EEG abnormalities occur in 30 to 70%. The incidence of these is significantly higher than that of ordinary children, suggesting that pediatric autism may be caused by encephalopathy. However, since it is extremely rare to be able to identify the site of brain damage, it is generally considered to be a disorder of the central nervous system function as a system.
従来、 小児自閉症の治療には主として療育法が採用されており、 患児 に対し精神療法、 行動療法、 感覚統合療法等を行い、 適切な社会生活が できるように訓練することが行われている。 薬物療法としては、 ピモジ ド ( 「オーラップ」 :藤沢薬品工業株式会社) が小児の自閉性障害に伴 う動き、 情動、 意欲、 対人関係等に見られる異常行動等の症状に適応を 取得している他、 テトラヒドロバイオプテリンが臨床治験に供されてい る。 しかしながら、 ピモジドは副作用が強いので小児に対する投与には 問題があり、 テトラヒドロバイオプテリンの有用性は未だ確立されたも のではない。 また、 上記の薬物以外には小児自閉症に対して有用な薬物 は知られておらず、 自閉症に対する適応を取得していない薬物を用いて 医師が経験的あるいは試験的に治療を行うにとどまっている。 Traditionally, nursing methods have been mainly used for the treatment of childhood autism.Psychotherapy, behavioral therapy, sensory integration therapy, etc. are performed on patients to train them to carry out appropriate social life. I have. As for pharmacotherapy, pimozide (“Olap”: Fujisawa Pharmaceutical Co., Ltd.) is adapting to symptoms such as abnormal behaviors such as movements, emotions, motivations, and interpersonal relationships associated with autistic disorders in children. In addition to the acquisition, tetrahydrobiopterin is being used in clinical trials. However, pimozide has problems in administration to children due to its strong side effects, and the usefulness of tetrahydrobiopterin has not yet been established. In addition, there are no known useful drugs for pediatric autism other than the above drugs, and doctors treat empirically or experimentally with drugs that have not been approved for autism Stays on.
従って本発明は、 小児自閉症に対して有効な薬物療法を可能にする治 療剤の提供を目的としている。 また本発明の別な目的は、 副作用が軽減 された小児自閉症の治療剤を提供することにある。  Accordingly, an object of the present invention is to provide a therapeutic agent that enables effective drug therapy for pediatric autism. Another object of the present invention is to provide a remedy for pediatric autism with reduced side effects.
本発明の自閉症治療剤の有効成分である 2-(4-メチルアミノブトキシ) ジフヱニルメタンは、 抗うつ作用を有することが報告されているほか (特公平 60 - 6349号公報) 、 脳卒中などの脳内器質性障害に起因する精 神機能症状の改善 ·治療剤として有用であることが知られている (特公 平 2-33689号公報) 。 2-(4-メチルアミノブトキシ) ジフエニルメタン 塩酸塩を有効成分とする薬剤 (一般名 「塩酸ビフニメラン」 ) は臨床に 供されており、 脳神経機能改善 (効能 ·効果:脳梗塞後遗症、 脳出血後 遺症に伴う意欲低下、 情緒障害の改善) を目的とする治療に用いられて いる。 発明の開示  It has been reported that 2- (4-methylaminobutoxy) diphenylmethane, which is an active ingredient of the therapeutic agent for autism of the present invention, has an antidepressant effect (Japanese Patent Publication No. 60-6349), It is known that it is useful as a therapeutic agent for ameliorating mental function symptoms caused by organic disorders in the brain (JP-B No. 2-33689). Drugs containing 2- (4-methylaminobutoxy) diphenylmethane hydrochloride as an active ingredient (generic name “bifunimerane hydrochloride”) have been clinically used to improve cranial nerve function. It is used for treatments aimed at improving motivation and emotional disorders associated with aftereffects. Disclosure of the invention
