Questions and Answers

What is the definition of pharmacodynamics of antibacterial drugs?

  • The study of drug absorption, distribution, metabolism, and excretion
  • The factors affecting the effectiveness of antibacterial drugs
  • The relationship between drug concentration and its antimicrobial effect (correct)
  • The principle and parameters of antibacterial drugs

    • Why is knowledge of a drug's antimicrobial pharmacodynamic effects important?

  • To understand the time course of drug absorption, distribution, metabolism, and excretion
  • To determine the dosing interval based on minimal inhibitory concentrations (MICs)
  • To define the pharmacokinetics of antibacterial drugs
  • To provide a rational basis for determination of optimal dosing regimens (correct)

    • What does pharmacokinetics refer to?

  • The principle and parameters of antibacterial drugs
  • The relationship between drug concentration and its antimicrobial effect
  • The study of the time course of drug absorption, distribution, metabolism, and excretion (correct)
