Problems solved by technology

But it also has its disadvantages. Because the viscosity of water is very low, the attachment time around the eyeball is short, and the tears secreted after the eye drops are applied to the eyes and other factors make the concentration of the drug dilute, and it is difficult to achieve a long time around the eyeball. For the purpose of maintaining a high concentration, an excipient is often added to the eye drops as a thickener to change the viscosity of the eye drops and regulate the residence time of the drug in the eye

Abstract

The invention belongs to the technical field of medicine preparation, and particularly relates to bromfenac sodium eye drops and a preparation method thereof. The eye drops comprise, by mass, 0.05-0.5% of bromfenac sodium, 0.03-0.2% of a thickening agent, 0.01-0.1% of bacteriostatic agents, 0.05-0.5% of antioxidant, 0.005-0.1% of complexing agents, and the balance water for injection, and the pH value is adjusted to 8.3 through a pH regulator. Compared with the prior art, acid mucopolysaccharide sodium hyaluronate which commonly exists in biological bodies is selected as the thickening agent by the bromfenac sodium eye drops, the water solution of the acid mucopolysaccharide sodium hyaluronate has good biocompatibility and high viscosity elasticity, due to the fact that the eye drops have the high viscosity elasticity, the residence time of drops in the eyes is prolonged, the problem that polymer impurities are prone to being generated when povidone serves as the thickening agent of an original product is solved, and the using safety and efficiency of the bromfenac sodium eye drops are increased.

Description

technical field [0001] The invention belongs to the technical field of medicine preparation, and in particular relates to a bromfenac sodium eye drop and a preparation method thereof. Background technique [0002] Bromfenac sodium is one of the derivatives of 2-amino-2-benzoylphenylacetic acid. Its structure is similar to ketoprofen and diclofenac. It is the most effective cyclooxygenase inhibitor with strong anti-inflammatory and analgesic effects. 10 times stronger than other NSAIDs. Bromfenac Sodium Eye Drops was developed by Senju Corporation of Japan and was launched in Japan in 2000 under the trade name Xibrom TM It was listed in the United States in early March 2005, and in October 2009 in China under the trade name Pronacle. It is mainly used for the symptomatic treatment of inflammatory diseases of the outer eye and anterior eye, such as blepharitis, conjunctivitis, scleritis (preserved episcleritis), postoperative inflammation, etc. Compared with other non-stero...
