ceftriaxone + co-amoxiclav + dicloxacillin

This is a combination of three antibiotics: ceftriaxone (a third-generation cephalosporin), co-amoxiclav (amoxicillin with clavulanic acid), and dicloxacillin (a penicillin-type antibiotic). While each component has established antimicrobial properties, this specific three-drug combination is not a standard fixed-dose combination product. Ceftriaxone works by preventing bacteria from making cell walls, while amoxicillin-clavulanate (co-amoxiclav) combines a penicillin antibiotic with a beta-lactamase inhibitor to overcome certain resistance mechanisms. Dicloxacillin is a penicillin-type antibiotic that also targets bacterial cell wall synthesis.
