局部麻醉药物如普鲁卡因等的分子组成有酯链或酰胺结构,故易被水解,稳定性较差。为了解此类药物的稳定性,本文根据国内外文献资料,对国内常用的三种局部麻醉药物(普鲁卡因、地卡因、苏夫卡因)的稳定性,作如下综述,以供有关工作者参考。一、普鲁卡因的稳定性本品分子组成有酯链和芳伯氨基结构,故易加水分解和氧化,其水解产物为对氨基苯甲
Local anesthetics such as procaine and other molecular composition of the ester chain or amide structure, it is easy to be hydrolyzed, poor stability. In order to understand the stability of these drugs, this article reviews the stability of three kinds of local anesthetics commonly used in China (procaine, dexamethasone and sevocaine) according to the domestic and international literature for the following For workers reference. First, the stability of procaine The molecular composition of the ester chain and aromatic primary amino structure, it is easy to add water decomposition and oxidation, the hydrolysis product of p-aminobenzoate
