PROBLEM TO BE SOLVED: To provide a method for preserving biomedicine for a long term, while suppressing degeneration of the biomedicine and deterioration in drug efficacy and without causing contamination by impurities.SOLUTION: A biomedicine preservation method for storing biomedicine in a medical multilayer molded container which is oxygen absorbent and includes at least three layers comprising: an oxygen absorbent layer (a layer A) which consists of an oxygen absorbent resin composition containing a polyester compound and a transition metal catalyst and a resin layer (a layer B) which contains thermoplastic resin and is laminated on both sides of the layer A. In the biomedicine preservation method, the polyester compound includes an element having at least one tetralin ring.COPYRIGHT: (C)2014,JPO&INPIT【課題】バイオ医薬の変質や薬効の低下を抑制し、不純物が混入すること無く、長期間保存できる方法を提供する。【解決手段】バイオ医薬を、ポリエステル化合物及び遷移金属触媒を含有する酸素吸収性樹脂組成物からなる酸素吸収層(層A)と、熱可塑性樹脂を含有する樹脂層(層B)を前記層Aの両側に積層した、少なくとも3層を含有する酸素吸収性医療用多層成形容器内に保存するバイオ医薬の保存方法であって、前記ポリエステル化合物が、少なくとも1つのテトラリン環を有する構成単位を含有する、バイオ医薬の保存方法。【選択図】なし
