BIOMEDICINE PRESERVATION METHOD

摘要

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.
