Quiz: Overview of Antibacterial Drugs
Question 1 of 3  

Which of the following is true for antibiotics that exhibit concentration-dependent bactericidal activity (eg, aminoglycosides, fluoroquinolones, daptomycin)?

  • A.

    Increasing their concentrations from levels slightly above the MIC to levels far above the MIC increases their rate of bactericidal activity.

  • B.

    The duration of these antibiotics' postantibiotic effect (PAE) is time-dependent.

  • C.

    If concentrations exceed the MIC, aminoglycosides and fluoroquinolones do not have a PAE on residual bacteria.

  • D.

    Aminoglycosides and fluoroquinolones are usually most effective as continuous infusions.

Am I correct?
