vancomycin therapeutic drug monitoring

I. Introduction

Vancomycin, a cornerstone in treating gram-positive bacterial infections, demands precision in dosing to ensure efficacy and minimize the risk of resistance. The integration of Area Under the Curve to Minimum Inhibitory Concentration (AUC:MIC) monitoring has become paramount for optimizing vancomycin therapy. This article explores the critical role of clinical pharmacists in managing Vancomycin AUC:MIC, delving into its significance, challenges, strategies, and impact on patient outcomes.
