Beta-lactam antibiotics generally show which type of antibacterial activity?
Correct answer: A. Time-dependent killing
- A. Time-dependent killing
- B. Concentration-dependent killing
- C. Delayed receptor antagonism
- D. Dose-independent killing
Explanation
The effectiveness of beta-lactams is mainly related to the time that free drug concentration remains above the pathogen's MIC. Increasing the peak concentration alone is less important than maintaining adequate exposure.
