| description | The purpose of the present invention is to remove, prior to administration, particles in a solution preparation filled in a syringe. The present invention provides an injection preparation in which a solution is filled in a syringe, wherein the syringe is provided with: a barrel which is formed in a cylindrical shape having a tip end part and a base end part, and at the tip end part of which is provided a discharge hole for discharging to the outside the solution accommodated inside the barrel; and a filter which, inside the barrel, is disposed further toward the base end side than the discharge hole. The filter is provided such that the solution flows from the base end side of the filter, through the filter, and to the tip end side. The filter is a membrane, and the material thereof is one or more materials selected from among polyethersulfone (PES), polyvinylidene fluoride (PVDF), polysulfone (PS), and acrylic copolymers. |
