Abstract

The present invention relates to the use of arteether maleate amine (SM934) for the preparation of ophthalmic preparations, and more particularly, to the use of arteether maleate amine for the preparation of ophthalmic preparations for the prevention or treatment of ocular inflammatory injuries caused by insufficient tear secretion.

Description

Technical field [0001] The present invention relates to the use of a new use of a molantide a ether amine, and the present invention is specifically a use of ethyl esterine in the preparation of an ophthalmic preparation for the treatment of tears. Background technique [0002] Dry eye, also known as dry cornea conjunctivitis, refers to a class of diseases of a type of disease due to the quality or amount of tears or an ocular discomfort caused by tear liquid kinetics. The clinical manifestation is a dry feeling, burning, foreign body sensation, itching, crying, eye red, blurred vision, vision and visual fatigue. Severe dry eyes can also cause corneal inflammation, corneal blood vessels, corneal ulcers, etc. Dry eye is mainly divided into lack of tears and evaporative overvoltage, meibus gland function disorders, dry syndrome, vitamin A deficiency, allergies, pregnancy, drug treatment can cause dry eye disease. With the development of social and economic development and increasin...
