cefazolin + moxifloxacin

Cefazolin + moxifloxacin is a combination of two antibiotics used for the treatment of bacterial infections, particularly when broad-spectrum coverage is desired. Cefazolin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis, primarily targeting gram-positive organisms. Moxifloxacin is a fluoroquinolone antibiotic that inhibits DNA gyrase and topoisomerase IV, enzymes essential for bacterial DNA replication and repair, providing activity against both gram-positive and gram-negative bacteria. This combination may be considered in clinical scenarios such as moderate to severe ocular infections (e.g., corneal ulcers) or other serious infections where dual coverage can help prevent resistance or ensure efficacy against mixed pathogens[1][3]. The use of this combination should be guided by susceptibility patterns and clinical judgment.
