Third-generation cephalosporins are semi-synthetic antibiotics with enhanced activity against Gram-negative organisms. The cephalosporins in biological samples are mostly determined using high-performance liquid chromatography (HPLC) and HPLC-mass spectrometry (LC-MS) or tandem mass spectrometry (LC-MS/MS). In recent years, numerous bioanalytical methods have been developed to improve the sensitivity and specificity of cephalosporin quantification using the powerful LC-MS/MS systems that are common in research laboratories. This review article presents recently developed bioanalytical methods by HPLC or LC-MS(/MS) for 12 third-generation cephalosporins, including five oral third-generation cephalosporins, and further discusses their application in pharmacokinetic studies of animals and humans.
第三代头孢菌素是对革兰氏阴性菌具有增强活性的半合成抗生素。生物样品中的头孢菌素大多采用高效液相色谱法(HPLC)、HPLC-质谱联用(LC-MS)或串联质谱法(LC-MS/MS)进行测定。近年来,人们开发了许多生物分析方法,以利用研究实验室中常见的强大的LC-MS/MS系统提高头孢菌素定量的灵敏度和特异性。本文综述了最近通过HPLC或LC-MS(/MS)针对12种第三代头孢菌素(包括5种口服第三代头孢菌素)开发的生物分析方法,并进一步讨论了它们在动物和人体药代动力学研究中的应用。
