Clinical Use of Antimicrobial Agents
Start with the big picture
Empiric therapy is selected before the pathogen is confirmed, using the infection’s likely cause, local resistance information, and patient risk factors. When culture and sensitivity results are available, treatment can be narrowed. Selection also depends on host characteristics such as pregnancy, organ function, immune status, allergy, and potential interactions. The lesson connects bactericidal or bacteriostatic activity with clinical context, and explains how pharmacodynamic behavior, tissue penetration, and impaired organ function influence drug choice and dosing. It also introduces appropriate reasons for combination therapy and prophylaxis, along with dosing strategies, adverse-effect monitoring, antimicrobial stewardship, and modification of treatment as new information emerges.
What you'll learn
- Select empiric therapy using likely pathogens, local resistance information, and patient risk factors.
- Explain how host factors influence antimicrobial choice.
- Distinguish bactericidal from bacteriostatic therapy and relate each to clinical context.
- Describe how pharmacodynamics, tissue penetration, and organ impairment affect treatment.
- Identify purposes of combination therapy, prophylaxis, and treatment modification.
