Augmentin is the brand name for a combination of amoxicillin and clavulanate potassium. Which two components are present?

• A. Amoxicillin and clavulanate potassium
• B. Amoxicillin alone
• C. Penicillin G and potassium
• D. Cefuroxime and clavulanate

Answer: (A)

This question tests understanding that Augmentin is a fixed combination of an antibiotic with a beta-lactamase inhibitor. The two components present are amoxicillin and clavulanate potassium. Amoxicillin provides the antibacterial action, while clavulanate potassium blocks beta-lactamase enzymes that some bacteria produce to inactivate beta-lactam antibiotics. By inhibiting these enzymes, clavulanate protects amoxicillin and broadens its activity against beta-lactamase–producing organisms. The other options don’t fit because they either omit clavulanate, use a different penicillin, or pair a different class of antibiotic with clavulanate.
