Which of the following antibiotics is NOT a first-generation cephalosporin?

Cefuroxime is categorized as a second-generation cephalosporin, distinguishing it from the first-generation cephalosporins. First-generation cephalosporins mainly include drugs like cefadroxil, cephalexin, and cefazolin, which are generally more effective against Gram-positive bacteria and have limited Gram-negative coverage. In contrast, cefuroxime has broader spectrum activity against Gram-negative bacteria, reflecting its classification as a second generation. Understanding the generational differences among cephalosporins is crucial for selecting the appropriate antibiotic based on the type of bacterial infection being treated.
