The preparation person manufacturing with fear and the simple operation of being polluted to the medicine which is the cell poisonous is possible, with the compact, at the same time designate the offer of the aqueous solution medicine formulation of the platinum complex where deterioration of the medicine is controlled as topic even the mothballing time.The aqueous solution which contains the platinum complex is accommodated in the oxygen permeable container, the aqueous solution medicine formulation of the platinum complex which features that it is filled up with the vapor to which the gap of the oxygen barrier characteristic container and the oxygen permeable container includes oxygen in the aqueous solution medicine formulation where furthermore the said oxygen permeable container is accommodated in the oxygen barrier characteristic container and becomes, is stabilized.調剤者が細胞毒性のある薬物に汚染される恐れなく、簡便な操作で調製することが可能であり、コンパクトで、かつ長期保存時にも薬物の劣化が抑制された白金錯体の水溶液医薬製剤の提供を課題とすること。白金錯体を含有する水溶液が酸素透過性容器に収容され、さらに該酸素透過性容器が酸素バリア性容器に収容されてなる水溶液医薬製剤において、酸素バリア性容器と酸素透過性容器との間隙が酸素を含む気体で満たされていることを特徴とする、安定化された白金錯体の水溶液医薬製剤。
