Area of Science:

  • Infectious Diseases
  • Microbiology
  • Pharmacology

Background:

  • Multidrug-resistant (MDR) gram-negative pathogens are increasingly prevalent.
  • Development of novel antimicrobial agents has significantly slowed.
  • Antimicrobial resistance necessitates innovative treatment strategies.

Observation:

  • Pharmacokinetic (PK) and pharmacodynamic (PD) principles are vital for guiding antibiotic therapy.
  • Susceptibility reports, including antibiograms, provide data for optimizing antimicrobial treatment.
  • Understanding resistance profiles of various antibiotic classes is essential.

Findings:

  • Review of pharmacodynamic principles for major antimicrobial classes (beta-lactams, carbapenems, aminoglycosides, fluoroquinolones, tetracyclines, glycylcyclines, polymyxins).
