Abstract

The invention provides curcumin nano micelle eye drops. The curcumin nano micelle eye drops comprise curcuminoid, a chitosan nano micelle drug carrier, a surfactant, a co-surfactant and medical pure water, wherein the mass volume percentage of curcuminoid is 0.005-0.02% and the mass volume percentage of the chitosan nano micelle drug carrier is 0.01-0.1%. The curcumin nano micelle eye drops provided by the invention are good in stability, high in bioavailability and low dosage.

Description

technical field [0001] The invention relates to the technical field of medicines, and mainly relates to an eye drop, in particular to an eye drop containing curcumin medicine, which can be used to prevent and treat eye diseases such as visual fatigue, cataract, retinopathy and the like. Background technique [0002] Eyes are organs that receive light and form images in the brain. They are delicate, complex and sensitive, enabling humans to obtain correct information in complex environments. Due to poor eye habits or degeneration of eye functions, various ophthalmic diseases are often prone to occur, which directly affect the patient's health status and behavioral ability. [0003] Various eye disorders including disorders of the front of the eye and the back of the eye, such as astigmatism, cataracts, conjunctivitis, corneal ulcers, dry eye syndrome, eyelid disorders, lacrimal gland tissue disorders, blocked lacrimal ducts, myopia, presbyopia, pupillary disturbances, refract...
