头孢菌素类抗生素具有抗菌谱广、抗菌作用强、组织体液浓度高、不良反应相对较轻、过敏少等特点,在临床上得到广泛应用,是治疗呼吸系统感染最主要的抗生素之一。新的头孢菌素类抗生素不断研发和使用,为治疗感染提供了更多的选择。1头孢菌素类抗生素分类及特点头孢菌素属β-内酰胺类抗生素,为杀菌剂,其作用机制为抑制细菌细胞壁的合成。根据研发顺序、抗菌谱、对β-内酰胺酶的稳定性和不良反应等,分为四
Cephalosporin antibiotics with broad antibacterial spectrum, strong antibacterial activity, high tissue fluid concentration, relatively mild adverse reactions, less allergy, is widely used in clinical practice, is one of the most important antibiotics for the treatment of respiratory infections. The new cephalosporin antibiotics continue to develop and use, for the treatment of infection provides more choices. 1 classification and characteristics of cephalosporins antibiotics cephalosporins β-lactam antibiotics, fungicides, its mechanism of action for the inhibition of bacterial cell wall synthesis. According to research and development order, antimicrobial spectrum, β-lactamase stability and adverse reactions, divided into four
