If a patient requires a combination therapy including a beta-lactamase inhibitor, which option would be appropriate from the list?

• A. Co-Amoxiclav
• B. Co-Trimoxazole
• C. Co-Trimazine
• D. Co-Trimethoprim

Answer: (A)

Beta-lactamase inhibitors are added to beta-lactam antibiotics to overcome bacterial resistance by preventing the enzyme from breaking down the drug’s beta-lactam ring. The option that combines amoxicillin with clavulanic acid includes this inhibitor, enabling activity against beta-lactamase–producing organisms. The other choices are antibiotic combinations that do not include a beta-lactamase inhibitor, so they wouldn’t provide protection against beta-lactamase–producing bacteria. Therefore, the amoxicillin-clavulanate combination is the appropriate choice.
