For the purpose of the storage in a stable manner of an aqueous liquid preparation containing a prostaglandin derivative that is liable to be adsorbed on a container and slightly soluble in water, an object of the present invention is to inhibit the decrease of the content of the prostaglandin derivative that is an active ingredient in the aqueous liquid preparation, taking into account of the material of the resin container. According to the present invention, a prostaglandin-containing product is provided, wherein an aqueous liquid preparation containing a prostaglandin derivative that is liable to be adsorbed on a container and slightly soluble in water is stored in a resin container formed from a polymer alloy of polyethylene terephthalate and polyarylate, thereby inhibiting the decrease of the content of the prostaglandin derivative in the aqueous liquid preparation. |
