【摘要】：目的實(shí)驗(yàn)考察頭孢噻肟鈉分別在酸性和堿性條件下的穩(wěn)定性及可能產(chǎn)生的降解產(chǎn)物,根據(jù)不同破壞條件下雜質(zhì)峰面積的變化情況對(duì)雜質(zhì)可能產(chǎn)生的來源進(jìn)行分析。方法按溶液顏色比較法測(cè)定不同破壞程度時(shí)的色級(jí),用UV方法測(cè)定不同破壞程度時(shí)頭孢噻肟鈉溶液的吸光度,以HPLC-UV測(cè)定雜質(zhì)含量的變化。結(jié)果頭孢噻肟鈉水溶液在酸性和堿性條件下色級(jí)和吸光度均會(huì)發(fā)生變化,藥品主成分含量有所下降,雜質(zhì)含量隨著破壞程度的加深而增加或降低,特別在堿性條件下變化更為明顯。結(jié)論頭孢噻肟鈉的穩(wěn)定性與pH有關(guān),相比酸性條件下,堿性條件對(duì)頭孢噻肟的穩(wěn)定性影響更大,頭孢噻肟鈉在堿性條件下降解程度更深,主要降解產(chǎn)物為去乙酰頭孢噻肟。
[Abstract]:Objective to study the degradation products of cefotaxime sodium were stable in acidic and alkaline conditions and possible, according to the analysis of changes in source area of different failure condition of impurity peaks on the possible impurities. Methods different color grade damage when measured by solution color comparison method to determine the absorbance of cefotaxime sodium the solution of different damage degree with UV method, change of impurity content was determined by HPLC-UV. The results of cefotaxime sodium in acidic and alkaline conditions the color and absorbance are changed, the drug containing principal component decreased, with the damage degree of impurity content increased or decreased, especially in alkaline conditions. The change is more obvious. Conclusion the stability of cefotaxime sodium and pH, compared to acidic conditions, effects of alkaline conditions on the stability of cefotaxime more, cefotaxime sodium The degradation degree of the main degradation product is deacetyl cefotaxime under the alkaline condition.
