Abstract

An eyedrops of matrine for treating bacterial or viral keratitis and conjunctivitis, xerophthalmia, and eyeground arteriosclerosis is prepared through heating the water for injection, stirring while adding matrine and sodium chloride, regulating pH=6.5-7.5, stirring while sequentially adding ethyl p-hydroxybenzoate, sodium hyaluronate and the water for injection, boiling, aseptic filtering, cooling, and loading in containers.

Description

technical field [0001] The invention relates to the technical field of medicines for human use, in particular to matrine eye drops and a production method thereof. Background technique [0002] As we all know, keratitis and conjunctivitis are eye diseases caused by bacteria or viruses, which seriously affect the health and vision of human eyes. At present, the clinical treatment of bacterial conjunctivitis and keratitis generally requires antibiotics combined with corticosteroids; for viral eye infections, antiviral drugs combined with antibiotics are used to control secondary infections. The maximum capacity of the liquid in the conjunctival sac of a normal person is 20-30 μl, and in addition to 10 μl of normal tear fluid, it can hold a maximum of 20 μl of liquid medicine. Only a small part of the liquid medicine mixed with tears enters the eye through the cornea, and most of it is discharged from the lacrimal duct, so the bioavailability is very low. The simultaneous app...
