The present invention relates to the technical field of barrier medicine bottles, and aims to solve the problems that the existing barrier medicine bottles mostly realize barrier properties through structural design, resulting in a low upper limit of barrier performance that is difficult to break through. Specifically disclosed are a barrier medicine bottle and a preparation method thereof. From the inside to the outside of the bottle, the bottle body of the barrier medicine bottle comprises an inner layer, a secondary inner layer, a middle layer, a secondary outer layer and an outer layer which are sequentially laminated. The inner layer comprises polyethylene, the secondary inner layer comprises ethylene-methyl acrylate copolymer, the middle layer comprises ethylene-vinyl alcohol copolymer, cyclic polyolefin and modified montmorillonite, the secondary outer layer comprises ethylene-methyl acrylate copolymer, and the outer layer comprises polyethylene, cyclic polyolefin and modified montmorillonite. The barrier medicine bottle proposed by the present invention is composed of five layers of materials, has low oxygen and water permeability, strong barrier properties, and great application value in the packaging of medicines or foods.
