The ED50 is a metric representing the dose of a medication that produces the intended pharmacological effect in 50% of the patient population studied during clinical trials. This value is derived from clinical studies and is used to help clinicians determine the optimal initial dose for their patients. An interprofessional team of physicians, pharmacists, nurses, and other healthcare professionals is necessary to monitor medication efficacy and safety according to patient factors, such as renal or hepatic function changes, disease state, and drug interactions, and ensure optimal patient outcomes.[9]
According to the FDA, medications demonstrating a narrow therapeutic ratio, where the ratio between the median lethal dose (LD50) and median effective dose (ED50) is less than 2-fold, or when there is less than a 2-fold difference in minimum toxic concentrations and minimum effective concentrations in the bloodstream, require careful titration and vigilant monitoring for safe and effective utilization.
