PRESCRIPTIONS AND DRUGS: RATIONAL USE, CLINICAL CHALLENGES AND PUBLIC HEALTH IMPLICATIONS.

Abstract

The rational use of prescriptions and drugs is a cornerstone of effective healthcare systems. However, irrational prescribing, polypharmacy, antimicrobial resistance, and self-medication continue to pose serious global health threats. This study examines the principles of appropriate drug use, evaluates common prescribing errors, and analyzes their clinical and public health consequences. Using qualitative analysis of medical literature and international guidelines, the research identifies key factors influencing drug misuse, including lack of patient awareness, insufficient regulatory control, and healthcare system limitations. The findings highlight the need for evidence-based prescribing, patient education, and stronger pharmaceutical policies. Improving rational drug use can significantly enhance treatment outcomes and reduce healthcare costs.
