[PROBLEMS] Isosorbide dinitrate, which is useful as a prophylactic / therapeutic agent for ischemic heart disease, is adsorbed on polyethylene, polypropylene, etc., which are currently used as materials for syringes and infusion bags, and has a low content. It is known that it will decrease. Therefore, an object of the present invention is to provide a novel injection container which does not adsorb isosorbide dinitrate. The above problem can be solved by manufacturing an injection container using a material such as a cycloolefin copolymer or a cycloolefin polymer. Further, since the drug content does not decrease even when stored for a long period of time, it has become possible to produce a prefilled syringe preparation. |
