Abstract

The invention relates to a cyclosporine-containing composition and a preparation method thereof. The compound eye drops are prepared from cyclosporine, anti-inflammatory or antibiotic drugs, a surfactant, a stabilizer, a thickener, an isoosmotic adjusting agent, a pH adjusting agentr and water or oil, the preparation is a mixed suspension agent or an emulsion, and one or two of a high pressure homogenization method and a wet grinding technique is / are combined for use in the preparation method. The cyclosporine compound eye drops have the advantages that the ophthalmic tolerance is excellent, the drug utilization degree is high, the tear secretion of people suffering from xerophthalmia can be effectively improved, the tear film is stabilized, the anti-inflammation function of the anti-inflammatory or antibiotic drugs and the immunoregulation function of cyclosporine can be synergistically exerted, xerophthalmia can be effectively treated, and the compound eye drops have a better treatment effect compared with the separate application of cyclosporine.

Description

technical field [0001] The invention relates to a compound pharmaceutical preparation and a preparation method thereof, in particular to a cyclosporin compound eye drop and a preparation method thereof, belonging to the field of pharmaceuticals. Background technique [0002] With the rapid development and popularization of video terminals such as mobile phones and computers, the incidence of dry eye disease, which is clinically manifested as eye discomfort, tear film instability, visual disturbance and ocular surface inflammation, is increasing year by year. According to reports, the global incidence of dry eye is 5.5%-33.7%, while the incidence in my country is 21%-30%. The incidence is relatively high, which has brought a great impact on the lives of patients. Studies have shown that dry eye syndrome is caused by the secretion of lacrimal glands in the aqueous layer, secretion of the oil layer, insufficient secretion of the mucin layer, excessive evaporation of tears, unev...
