EVALUATION OF CLINICAL AND PHARMACOLOGICAL APPROACHES TO THE RATIONAL TREATMENT OF INFECTIOUS DISEASES

Abstrak

Infectious diseases remain a leading cause of morbidity and mortality worldwide despite advances in medical science and antimicrobial therapy. Rational treatment of infectious diseases requires an evidence‑based integration of clinical judgment, antimicrobial pharmacology, diagnostic accuracy, resistance surveillance, and antimicrobial stewardship principles. This article reviews current clinical and pharmacological strategies used in rational therapy, including appropriate antibiotic selection, dose optimization, treatment duration, de‑escalation practices, and personalized medicine approaches. Barriers to effective rational therapy, such as antimicrobial resistance, diagnostic challenges, and healthcare system limitations, are also discussed. Flowcharts and conceptual diagrams are included to illustrate clinical decision‑making pathways. Evidence supports that strategic application of pharmacokinetics/pharmacodynamics (PK/PD) principles and stewardship interventions improves patient outcomes and reduces the emergence of resistance.
