A patient is administered Augmentin (amoxicillin and clavulanate potassium) to treat otitis media. How does a beta-lactamase inhibitor agent achieve a therapeutic effect?
A) It extends the spectrum of antibacterial activity of penicillin.
B) It extends the spectrum of the beta-lactamase inhibitor.
C) It decreases the side effects of high-dose penicillin.
D) It increases the absorption of the penicillin.
A
Feedback:
When combined with a penicillin, the beta-lactamase inhibitor protects the penicillin from destruction by the enzymes and extends the penicillin's spectrum of antimicrobial activity. Augmentin does not extend the spectrum of beta-lactamase inhibitor. Augmentin does not decrease the side effects of high-dose penicillin. Augmentin does not increase the absorption of penicillin.
