What is the primary goal of Therapeutic Drug Monitoring (TDM)?

The primary goal of Therapeutic Drug Monitoring (TDM) is to increase medication effectiveness and safety. TDM involves measuring drug levels in a patient's bloodstream to ensure that they are within a targeted therapeutic range. This process is crucial because certain medications require careful dose adjustments based on individual patient characteristics, such as age, weight, organ function, and concurrent medications, which can significantly impact how a drug is metabolized and eliminated. By monitoring these levels, healthcare providers can optimize dosages, minimize toxicity, and ensure that the medication is providing the desired therapeutic effect.

Furthermore, TDM is especially important for drugs that have narrow therapeutic windows, where the difference between an effective dose and a toxic dose is small. By keeping drug concentrations within an optimal range, TDM helps in preventing adverse drug reactions and enhancing the overall treatment outcome for patients.
