Outline of Annual Research Achievements

メディカルハーブや植物性サプリメントとの薬力学的相互作用に着目し、周術期に麻酔薬や麻酔関連薬の有用・有害効果が変化する可能性を追究することを目的に、実験的研究ならびに理論的構築を行った。その結果、以下のような成果を得た。

最終年度研究成果:飲食物由来のβ-カルボリンアルカロイドが全身麻酔薬や局所麻酔薬と相互作用する結果、プロポフォールとリドカインの麻酔効果が減弱する機序的仮説を構築した(成果発表:Medical Hypotheses)。アルカロイドとの相互作用を含む局所麻酔薬の臨床効果の変化に関し、薬力学的ならびに薬物動態学的な機序を総括した。さらに、麻酔効果減弱に対する有効な臨床的対策を考察した(成果発表:International Journal of Clinical Anesthesiology)。

研究期間全体を通した成果:種々の麻酔薬が生体膜に作用し、周術期酸化ストレス低下効果(成果発表:Oxidants and Antioxidants in Medical Science)、虚血再灌流傷害保護効果(成果発表:Open Journal of Anesthesiology)を示す可能性を得た。また、麻酔薬に加えて麻酔関連薬や鎮痛薬も、膜活性をもつことを解明した(成果発表:British Journal of Pharmaceutical Research)。そして、ハーブやサプリメントに含まれる植物成分も同様の膜作用機序を有することから、麻酔薬と薬力学的に相互作用して麻酔効果に影響を及ぼす潜在的可能性を総括し(成果発表:Molecules)、ハーブ成分のアルカロイドがリドカインと相互作用することを実験的に明らかにした(成果発表:Journal of Drug and Alcohol Research)。
