PROSTAGLANDIN F2alpha; DERIVATIVE CONTAINING PRODUCTS

摘要

The invention provides a resin-made container which enables long-term stable preservation of aqueous liquid preparations containing prostaglandin F2E derivatives having fluorine atoms in the molecule. An aqueous liquid preparation containing a prostaglandin F2E derivative having a fluorine atom in the molecule is protected from lowering in the prostaglandin F2E derivative content by keeping the preparation in a container made of a propylene/ethylene copolymer having a propylene/ ethylene ratio of 94.0/6. 0 to 99.5/0.5.
