Description
今日まで、うつ病の治療に用いられている薬物の多くは、ノルエピネフリン又はセロトニン再取り込みを選択的に阻害するものである。そのような薬剤としては、例えば、イミプラミン(第一世代の抗うつ薬)、マプロチリン(第二世代の抗うつ薬)、フルオキセチン(Fluoxetine)で代表される選択的セロトニン取り込み阻害薬(SSRI、第三世代の抗うつ薬)、ベンラファキシン(Venlafaxine)で代表されるセロトニン及び/又はノルエピネフリン再取り込み阻害剤(SNRI、第四世代の抗うつ薬)等が挙げられる(非特許文献1)。
本発明は、公知の抗うつ薬に比べ幅広い治療スペクトラムを有し、短期間で十分な治療効果を発現することができる薬剤を提供することを課題とする。
