Austin Morrison, Infectious Diseases and Antimicrobial Stewardship Clinical Pharmacist at the Moffitt Cancer Center and Research Institute, presents a talk on the pharmacokinetic and pharmacodynamic principles associated with the optimal dosing of antimicrobial agents. Dr. Morrison begins by defining basic antimicrobial concepts, including absorption, distribution, metabolism, and excretion. He then compares and contrasts concentrationdependent versus timedependent killing as it applies to different antimicrobial classes. Dr. Morrison then specifically singles out betalactams and timedependent killing and the benefits of extended dosing strategies. He also discusses the significance of the AUC/MIC curve. Lastly, Dr. Morrison concludes by discussing antibiotic dosing in renal insufficiency and the ideal strategies for this group of patients.
