Clavulanic acid does what?

Clavulanic acid does what?

• A. Inhibits beta-lactamase (does NOT kill bacteria)
• B. Kills bacteria
• C. Increases beta-lactamase production
• D. Acts as a penicillin receptor agonist

Answer: (A)

Beta-lactamase enzymes produced by bacteria degrade beta-lactam antibiotics, so drugs are blocked from reaching their target. Clavulanic acid counteracts this by binding to these enzymes and inactivating them, usually irreversibly. This protection lets the accompanying penicillin work better against the bacteria, since the antibiotic can reach the penicillin-binding proteins and disrupt cell wall synthesis. Clavulanic acid itself has little direct antibacterial effect, so it doesn’t kill bacteria on its own. It also doesn’t increase beta-lactamase production or act as a penicillin receptor agonist.
