Abstract

The invention discloses a medicinal composition for treating perimenopausal xerophthalmia. The medicinal composition has the innovative structure shown in the description. The medicine provided by the invention can obviously improve the dry eye SIT caused by decrease of the perimenopausal gonadal hormone concentrations, change the tear protein components, promote the eyelid glandular secretion, and effectively reduce the inflammatory cell infiltration of the androgen dysfunctional xerophthalmia and the basal cellular atrophy of the corneal epithelium, belongs to a medicine which is safe and effective, has the simple administration route, has small side effects, and can be used by patients for a long term in treating the dry eye disease, and therefore, the medicinal composition has the wide clinical application and promotion values.

Description

technical field [0001] The invention relates to the field of medicine, in particular, the invention relates to a pharmaceutical composition for treating perimenopausal dry eye syndrome. Background technique [0002] Dry eye syndrome is an unstable tear film and ocular surface damage caused by abnormal tear quantity or quality, which seriously affects the vision and life of patients, and the prevalence rate is increasing year by year. The eye is one of the important target organs for the action of sex hormones. The level of sex hormones decreases, the tear film is unstable, and the local inflammatory response increases, leading to the formation of dry eye. For patients with dry eye syndrome caused by decreased androgen levels, local symptomatic treatment is currently used, but androgen replacement therapy has many side effects and is not easy for patients to accept. Therefore, finding an alternative drug in clinic has become an urgent problem to be solved in ophthalmology. ...
