The Essentials of Antibiotic Dosing

Pharmacotherapy specialist Kristin Zeitler, PharmD, from Tampa General Hospital in Tampa, FL, presents this talk on the basics of antimicrobial therapy management for hospital patients. Dr. Zeitler begins by emphasizing the important of the ID clinical pharmacist. She then compares and contrasts Pharmacokinetics (PK) , the way drugs move through the body, with Pharmacodynamics (PD), the relationship between serum drug concentration and the therapeutic/toxic effects of the drug. PK/PD effects of antimicrobials are then further explored. Dr. Zeitler goes on to discuss Vancomycin dosing strategies, the effects of serum albumin on serum antimicrobial drug levels, drug penetration into the site of interest, drug dosing strategies for patients with renal insufficiency, and the effects of obesity and critical illness on antimicrobial dosing strategies.
