What is the combination name for Amoxicillin with Clavulanic acid?

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

Answer: (A)

Combining amoxicillin with clavulanic acid works by using a beta-lactamase inhibitor to protect the antibiotic from destruction by certain bacterial enzymes. Clavulanic acid blocks beta-lactamases, enzymes some bacteria produce to inactivate beta-lactam antibiotics. By inhibiting these enzymes, amoxicillin can act against beta-lactamase–producing bacteria, extending its spectrum. The fixed-dose product name used for this combo is co-amoxiclav, reflecting amoxicillin with clavulanic acid.

The other options refer to different antibiotic combinations (for example, trimethoprim with sulfamethoxazole) that do not include clavulanic acid, so they don’t represent this specific pairing.
