Brand name for amoxicillin combined with clavulanic acid

Brand name for amoxicillin combined with clavulanic acid

• A. Augmentin
• B. Zosyn
• C. Amoxil
• D. Unasyn

Answer: (A)

This question tests recognizing the brand name of the antibiotic combination and understanding why that combination is used. Amoxicillin is a penicillin-type antibiotic, but many bacteria produce beta-lactamase enzymes that can inactivate it. Clavulanic acid is a beta-lactamase inhibitor that protects amoxicillin from being destroyed, expanding its effectiveness against beta-lactamase–producing organisms. Together, they form a single product marketed as Augmentin. The other options refer to different drugs or combinations: one is a different beta-lactam–beta-lactamase inhibitor pair (piperacillin-tazobactam), another is amoxicillin alone, and another is ampicillin–sulbactam.
