Beta-lactamase inhibitors inhibit beta-lactamase but do not kill bacteria.

Beta-lactamase inhibitors inhibit beta-lactamase but do not kill bacteria.

• A. They directly kill bacteria
• B. They inhibit beta-lactamase but do not kill bacteria
• C. They degrade penicillin
• D. They are used as antiviral agents

Answer: (B)

The main idea is that beta-lactamase inhibitors block the bacterial enzymes that destroy beta-lactam antibiotics, rather than killing bacteria themselves. They don’t have direct antimicrobial activity; instead, they protect the antibiotic from being degraded by beta-lactamase enzymes produced by some bacteria. This allows the antibiotic to remain active and exert its effect on the bacteria. They are often used in combination with a beta-lactam antibiotic to extend its spectrum against beta-lactamase–producing organisms. They do not degrade penicillin themselves, and they are not antiviral agents.
