CLAV guards AMOX from some enzyme scissors.
The idea behind the cue
Susceptible bacterial infections. Inhibits cell-wall synthesis while clavulanate inhibits selected beta-lactamases. Key safety: Hypersensitivity, diarrhea and hepatic injury. Monitor: Clinical response, allergy and renal suitability. Counseling: Take at the start of a meal; formulations are not always interchangeable by tablet count.

A prescriber selects amoxicillin/clavulanate rather than amoxicillin alone. What does clavulanate contribute?
A. Inhibition of selected bacterial beta-lactamases.
B. Direct inhibition of all penicillin-binding-protein resistance mechanisms.
C. Prevention of penicillin hypersensitivity by binding the allergen.
D. Independent reliable coverage of every ESBL- and carbapenemase-producing isolate.
Reveal explanation
Inhibition of selected bacterial beta-lactamases.
Clavulanate protects amoxicillin against certain beta-lactamases but does not overcome every resistance mechanism or allergy.
