Abstract

The invention belongs to the technical field of eye drops, and particularly relates to eye drops for delaying treatment of juvenile myopia and a preparation method thereof. The eye drops are preparedfrom the following components in percentage by weight: 0.005 to 1 percent of atropine or pharmaceutically acceptable salt thereof, 0.1 to 10 percent of a thickening agent, 0.001 to 0.5 percent of a complexing agent, 0.001 to 0.05 percent of a bacteriostatic agent, a pH value regulator, 0.1 to 0.9 percent of an osmotic pressure regulator and a proper amount of water for injection, wherein the pH value regulator is used for regulating the pH value of the eye drops to 3.5 to 6.5. According to the preparation method, hydroxypropyl methylcellulose sprayed by a spray gun A is fused by the water forinjection sprayed by a spray gun B, and meanwhile, a solution in a rectangular pool forms liquid rotational flow under the impact of the water for injection, so that the solution flows in the rectangular pool, the dissolving efficiency of the hydroxypropyl methylcellulose is improved, and the preparation efficiency of the eye drops for delaying treatment of juvenile myopia is further improved.
