Clinical Insights into Narrow Therapeutic Index Drugs
Journal Title: International Journal of Current Science Research and Review - Year 2025, Vol 8, Issue 03
Abstract
Medications with a narrow therapeutic index (NTI), such as phenytoin, warfarin, and vancomycin, require precise dosing to avoid adverse effects and ensure they remain effective. This is particularly important for at-risk groups like elderly individuals or those with multiple health conditions. The therapeutic index (TI) is a key measurement that indicates the range between a drug’s therapeutic and toxic levels. NTI drugs need careful management because even small changes in their concentration can lead to significant risks and impact their therapeutic benefits. Factors unique to each patient, such as age, existing health conditions, and genetic differences, can affect how NTI drugs are metabolized and their overall effectiveness. As a result, therapeutic drug monitoring (TDM) is crucial for tailoring dosing strategies and minimizing the risk of harm. Interactions between NTI drugs and other medications, especially those that involve cytochrome P450 enzymes, can influence drug concentrations, making treatment more complex. The growing field of personalized medicine, which includes pharmacogenomics, aims to improve outcomes by customizing drug therapies based on individual genetic characteristics. Proper management of NTI drugs requires teamwork among healthcare professionals, including doctors, pharmacists, and nurses. Continued research, along with advancements in drug delivery systems and artificial intelligence, holds potential to enhance the safety and effectiveness of NTI medications.
