Cefixime belongs to which antibiotic class?

Cefixime belongs to which antibiotic class?

• A. Quinolones
• B. Macrolides
• C. Cephalosporin
• D. Penicillin

Answer: (C)

Cefixime is a cephalosporin, a beta-lactam antibiotic in the cephalosporin family. Cephalosporins work by inhibiting penicillin-binding proteins, preventing proper cross-linking of the bacterial cell wall, which leads to cell lysis. Cefixime is a third-generation oral cephalosporin with strong activity against many Gram-negative bacteria and useful activity against some Gram-positives, making it a versatile option for various infections treated outpatient. This distinguishes it from quinolones, which inhibit DNA gyrase/topoisomerase IV; macrolides, which block protein synthesis at the 50S ribosomal subunit; and penicillins, which are another beta-lactam class with a different spectrum and resistance profile.
