Abstract

The invention discloses a riboflavine sodium phosphate composition injection and a preparation method thereof. The riboflavine sodium phosphate composition injection comprises riboflavine sodium phosphate, citric acid, sodium hydroxide and sodium chloride. Each injection contains 5 to 15mg of riboflavine sodium phosphate, 2.1mg of citric acid, 2 to 4mg of sodium hydroxide and 0.6 to 0.8mg of sodium chloride. The preparation method comprises the following steps: adding water used for injection into the citric acid for stirring and dissolving; adjusting the pH to about 6.2 with sodium hydroxide; adding sodium chloride for stirring to dissolve the sodium chloride; adding the water used for injection and 1g of active carbon; adding riboflavine sodium phosphate while stirring; after the riboflavine sodium phosphate is completely dissolved, complementing the water for injection until the total amount is completely complemented; performing filtering, refluxing, filling, nitrogen charge, melting to seal, sterilizing at a high temperature; and after reducing the temperature, detecting with lamps, packing and checking, and obtaining the finished product. The riboflavine sodium phosphate composition injection does not crystallize, has good clarity and stability, and is helpful for improving the yield of the product, reducing the market rick of the product and is better applied to clinical treatment.

Description

Technical field [0001] The invention relates to medicines in the field of medicine, in particular to a riboflavin sodium phosphate composition injection with good clarity and stability without crystallization and a preparation method. Background technique [0002] Riboflavin is a component of the human body’s metabolic enzyme system, and it is also one of the indispensable vitamins in biological life activities. It is closely related to the metabolism of carbohydrates, fats, proteins, and nucleic acids in the human body. The activity is flavin mononucleotide (FMN) and flavin purine dinucleotide (FAD) two flavin coenzymes. These two flavin coenzymes can form flavin proteins with a variety of proteins and participate in the biological oxidation reaction and energy of the organism. Metabolism, they are also a necessary component of the mixed-function oxidase system in the body's cells. This enzyme system is the main enzyme system for the metabolic activation or detoxification of che...
