Abstract

The advancement of drug therapy has undoubtedly elevated patient care standards. However, it has also led to an increase in Drug-Related Problems (DRPs), which can have a significant impact on health outcomes. In an 18-month prospective observational study involving 2,000 patients, we meticulously assessed DRPs using the Hepler and Strand classification system. These DRPs encompassed a range of issues, including adverse drug reactions (ADRs), untreated medical indications, non-compliance with prescribed regimens, improper drug selection, and more. Our data collection adhered to a well-validated and pre-tested format. Among 2,000 patients, 106 (5.3%) experienced 117 DRPs, averaging 1.1 per patient. Adverse drug reactions (ADRs) accounted for 47.01% of cases, non-compliance 35.89%, and drug use without indication 11.32%. ADR incidence was 2.75%, primarily affecting the Gastrointestinal (GIT) system. Antibiotics were frequently associated with ADRs in various drug classes. Vigilant monitoring, robust reporting mechanisms, and patient education are pivotal strategies in the prevention of drugrelated issues. Pharmacovigilance, the systematic monitoring and evaluation of drug safety and efficacy, plays a fundamental role in ensuring the delivery of high-quality healthcare. Through the effective implementation of robust pharmacovigilance practices, we can successfully diminish the occurrence of DRPs, leading to safer and more efficacious outcomes in drug treatment.
