中文名称:头孢噻肟;头孢氨噻;氨噻肟头孢菌素钠;头孢噻肟酸
英文名称:cefotaxime;cephotaxime;(((2-amino- 4-thiazolyl)methoxyimino)acetyl)amino)-8-oxo-, (6r-(6alpha,7beta(z) 3-[(Acetyloxy)methyl]-7-[[(2-amino-4-thiazoly)(methoxyimino)acethyl]amino]-8-oxo-5-thia-1-azabicyclo[4,2,0]oct-2-ene-2-carboxylic acid(sodium salt)
性状描述:白色粉末。熔点162-163℃(分解)。易溶于水。稀溶液无色或微黄色,浓度较高时呈灰黄色。变质时呈深黄色或棕色。
生产方法:以发酵生产的头孢菌素C为原料,经裂解得7-氨基头孢烷酸(7-ACA),再经硅酯化,与侧链酸缩合;水解;结晶得头孢噻肟,再与醋酸钠成盐,经脱色;无菌过滤;结晶得到头孢噻肟(钠盐)成品。
用途:半合成肟型头孢菌素,为第三代头孢菌素。本品对革兰阴性菌;尤其对肠杆菌作用强大。主要用于敏感菌所致呼吸系统感染,泌尿系统感染,胆道及肠道感染,皮肤及软组织感染,烧伤和骨关节感染等。
