[0048] Experimental example 1: Comparative experiment

[0049] (1) A batch of amikacin sulfate injection was prepared according to the prescription and preparation method disclosed in "A preparation method of amikacin sulfate injection" (patent number CN101584658A), batch number: 110801A·S, specification 2ml: 0.2 g, as follows:

[0050] 1. Measure 150ml of water for injection (about 75% of the total preparation), stir and heat to 45°C;

[0051] 2. Weigh 0.18g disodium ethylenediaminetetraacetic acid and 40g amikacin sulfate, add them to the above aqueous solution, stir until completely dissolved; adjust the pH to 5.50 with lactic acid;

[0052] 3. Add water for injection to 80% of the total volume of Amikacin Sulfate Injection, and then adjust the pH to 6.00 with lactic acid;

[0053] 4. Add water for injection to 200ml, while cooling to 20~30℃

[0054] 5. Add 0.1% activated carbon, stir for 20 minutes, and filter;

[0055] 6. Potting and sterilizing at 115℃ for 30 minutes.

Abstract

The invention discloses amikacin sulfate injection and a preparation method thereof. Antioxidants, complexing agents and injection water are added into amikacin sulfate. The amikacin sulfate injection and the preparation method thereof have the advantages that production technology is simple, cost is low, the problem that existing amikacin sulfate injection cannot meet the terminal sterilization requirement is solved, shortcomings of the prior art are overcome, and the preparation method is applicable to modernized production.

Description

Technical field [0001] The invention relates to an injection of amikacin sulfate and a preparation method thereof. Background technique [0002] Amikacin Sulfate Injection is a semi-synthetic aminoglycoside antibiotic, stable to most aminoglycoside inactivating enzymes, so it is especially suitable for treating gram-negative bacilli that are resistant to kanamycin, gentamicin or tobramycin Severe infections caused by drug strains have been widely used clinically. [0003] In the existing patents and literature, the amikacin sulfate injection reported by CN101584658A is a veterinary drug, and its prescription only adds edetate disodium, and the sterilization conditions are unclear. According to the prescription process we provided, we sterilized it at 115°C for 30 minutes. As a result, the color of the sample became obviously yellow, which did not meet the standard. In order for Amikacin Sulfate Injection to meet terminal sterilization, its prescription process must be improved. ...
