Pharmacokinetics and Pharmacodynamics of Antimicrobials

Show Summary Details

Preview

Pharmacokinetics is the disposition of drugs in the body (how the body acts on the drug); it incorporates terms such as absorption, bioavailability, distribution, protein binding, metabolism, and elimination. Pharmacodynamics is the interaction between the drug concentration at the site of action over time (drug exposure) and the pharmacologic effect, which, in the case of antimicrobials, is eradication of microorganisms. Pharmacokinetics and pharmacodynamics are interrelated. Both need to be taken into account to optimize antimicrobial therapy.
