Problems solved by technology

The current inspection method still has some problems in controlling and evaluating the quality of drugs. The controllability of the content determination is not very good, and the quality of related substances cannot be effectively measured. The inspection method for content and related substance inspection items can be further improved

Abstract

The invention relates to Arbekacin sulfate, in particular to a method for detecting Arbekacin sulfate and impurities thereof. The method for detecting the Arbekacin sulfate and the impurities of the Arbekacin sulfate is obtained through optimization. The HPLC-PAD method for determining the content of the arbekacin sulfate and the related substances is established for the first time, and compared with a Japanese pharmacopeia loading method, the specificity is good, and the method is durable.

Description

technical field [0001] The invention relates to arbekacin sulfate, in particular to a detection method for arbekacin sulfate and impurities thereof. Background technique [0002] Arbekacin Sulfate (ABK) is an aminoglycoside antibiotic discovered by Umezawa Paifu of the Institute of Microbial Chemistry in Japan and developed by the Japanese Meiji Seika Pharmaceutical Company. It was put on the market in 1990. The antibacterial mechanism of arbekacin is to inhibit the synthesis of bacterial proteins. Arbekacin is similar to dibekacin, stable to various inactivating enzymes, can form a three-dimensional barrier to inactivating enzymes structurally, and has a high degree of antagonistic effect on aminoglycoside inactivating enzymes. The improvement of clinical symptoms of this type of drug is proportional to the dosage, which is dose-dependent, and has the strongest post-antibiotic effect (PAE) among antibiotics, and it is still valued clinically so far. [0003] The structure...
