Abstract

The invention relates to a gel for lysozyme eye and a preparation method thereof. The gel for the lysozyme eye is applicable of treating various normal eye infection diseases, such as a pinkeye, an ophthalmia, a ceratitis, a keratohelcosis, a conjunctivitis and the like, which is caused by bacteria, Chlamydia, virus and drug-resistance bacteria. The gel for the lysozyme eye disclosed by the invention uses a solution containing 0.1-10.0% of lysozyme, 0.01-20% of water soluble macromolecule matrix, 0.1-10% of a pH modifier, 0.01-10% of a bacteriostat and 0.1-10% of a viscosity modifier and takes a solution with a pH value of 5.0-6.5 as a buffer solution. With the adoption of the receipt of the gel for the lysozyme eye provided by the invention, the time that drug lysozyme remains on an eye can be prolonged, and the bacteriostat efficiency of the lysozyme on the eye can be improved.

Description

technical field [0001] The invention relates to the field of biotechnology, and relates to a lysozyme ophthalmic gel and a preparation method thereof. The gel treats various pink eye diseases, keratitis, corneal ulcers, Common eye infections such as conjunctivitis. Background technique [0002] Common clinical infectious eye diseases, such as conjunctivitis and keratitis, are mostly bacterial infections. At present, antibiotic eye drops are the most commonly used for the treatment of bacterial eye diseases, but drug resistance is prone to develop. With the extensive use of antibiotics, drug-resistant strains are also increasing. And antibiotic eye drops should not be used for a long time because of their side effects. Therefore, the development of new ophthalmic preparations for the treatment of bacterial eye diseases has become a research hotspot. [0003] Lysozyme is a non-specific immune factor that exists in the normal body fluids and tissues of the human body. It has...
