头孢匹罗（cefpirome）是第四代新型半合成广谱β－内酸胶类头孢菌素，具有最小的浓度依赖性杀伤作用，仅对金黄色葡萄球菌产生延续的抗生素后效应。这些药效学特点提示，最佳的剂量应使在用药间隔期的大部分时间内头孢匹罗的血清浓度大于对感染性病源体的最小抑菌浓度（MIC）
Cefpirome is the fourth generation of a novel semisynthetic, broad-spectrum β-endocarpine cephalosporin with minimal concentration-dependent killing and a sustained post-antibiotic effect on Staphylococcus aureus. These pharmacodynamic characteristics suggest that the optimal dose should be such that the serum concentration of cefpirome is greater than the minimum inhibitory concentration (MIC) against infectious agents over most of the dosing interval,
