磺胺醋酰(Sulfacetamide),是一种磺胺类人工合成抗菌药[1],主要通过局部用药治疗局部感染,也可以口服用于治疗泌尿道感染[2]

特性

[编辑]

磺胺醋酰室温下呈白色,水溶性强。磺胺醋酰的药物活性在磺胺类药物中处于较低水平。人口服后,磺胺醋酰能得到很好吸收,其半衰期大约是9小时,大约70%服用的磺胺醋酰会以未代谢状态经尿液排出[2][3]:341

磺胺醋酰对大部分的革兰氏阴性菌革兰氏阳性菌有杀灭作用。磺胺醋酰杀灭细菌的机理和其他的磺胺类药物相似。细菌的正常生长依赖叶酸的合成,合成通路中,对氨基苯甲酸(PABA)是一种必需的前体。而磺胺醋酰结构与对氨基苯甲酸相似,因而可以和对氨基苯甲酸竞争,对叶酸的合成进行抑制[4]。 磺胺醋酰的钠盐磺胺醋酰钠亦是一种抗菌药物,可以用于治疗皮肤感染[5]

临床

[编辑]

磺胺醋酰主要通过局部用药的方式(比如皮肤涂抹、滴眼液滴眼)治疗局部感染,如皮肤感染。此外,口服磺胺醋酰亦是一种过去使用的治疗泌尿道感染的方法。磺胺醋酰可能产生的副作用和磺胺类药物的典型副作用类似[2][3]:341[4]
