Abstract

The invention relates to a polyketone iodine eyedrops, and relative production, wherein it adds polyketone iodine into osmotic pressure adjuster, stabilizer, and pH adjuster to be dissolved, and using pH adjuster to realize constant volume; pH adjuster at 100 volume units contain 0.1-0.5 units of polyketone iodine, 0.35-0.65 osmotic pressure adjuster mass units, stabilizer at 0.05 mass units; the pH of osmotic pressure adjuster is 6.0-6.8. The invention can treat kinds of ceratitis, with high safety but no side effect.

Description

technical field [0001] The invention belongs to medicines for treating eye diseases, in particular to an eye drop with povidone-iodine as the main medicine. Background technique [0002] Povidone-iodine has been widely used in clinical external disinfectants, and the main function of povidone-iodine is disinfection and antisepsis. The second part of Chinese Pharmacopoeia 2005 edition has been recorded. Chinese patent discloses multiple povidone-iodine external preparations, such as the ointment disclosed in 93111431.4, which cannot be directly used in eyes; as the disclosed povidone-iodine foam in CN03143440.1, it cannot be directly used in eyes either. There is no literature yet to disclose whether povidone-iodine can be used for the treatment of eye diseases, and whether it has negative effects on the eyes. Contents of the invention [0003] The object of the present invention is to provide a kind of povidone iodine eye drop and preparation method for the treatment of ...
