Problems solved by technology

Although levofloxacin hydrochloride itself has a certain antibacterial effect, its bacteriostatic effect cannot be used as a criterion for judging whether to add bacteriostatic agents to ophthalmic preparations (references: Ning Lili, Zhao Deheng, "No addition of bacteriostatic agents to multi-dose ophthalmic preparations Thoughts on "Drug Evaluation and Application Center of the State Food and Drug Administration, Electronic Journal 2008-9-12)
Therefore, the safety of multi-dose ophthalmic formulations without bacteriostats remains highly controversial and has not yet been unanimously approved

Abstract

The invention discloses disposable levofloxacin hydrochloride eye drops and a preparation method thereof. The disposable levofloxacin hydrochloride eye drops comprise levofloxacin hydrochloride, a pH regulator, an isotonic agent, a stabilizing agent, a thickening agent, and the like; and the preparation method adopts a bacteria-free bottling process or an autoclaving process. In addition, the eye drops are independently packaged in single dose for disposable use, thereby the sterility performance of products is guaranteed and the products are more safe, reliable, simple, convenient, and sanitary.

Description

technical field [0001] The invention belongs to the field of pharmacy, in particular to a disposable levofloxacin hydrochloride eye drop without bacteriostatic agent and a preparation method thereof. Background technique [0002] Levofloxacin hydrochloride eye drops are used to treat bacterial conjunctivitis and bacterial keratitis caused by sensitive bacteria. All the levofloxacin hydrochloride eye drops on the market are packaged in multiple doses for repeated use. Once the preparation is opened, it is easy to be contaminated by tears and microbes in the air during use and storage, thereby causing safety hazards. In order to prevent ophthalmic preparations from being contaminated by microorganisms during repeated use after opening, bacteriostatic agents (preservatives) are added to ophthalmic preparations, which are used in almost all eye drop prescriptions in the "Chinese Hospital Preparation Specifications" antibacterial agent. Bacteriostatic agents, also known as pre...
