What does therapeutic drug monitoring primarily aim to achieve?

Therapeutic drug monitoring primarily aims to maintain a constant drug concentration in the bloodstream, which is essential for optimizing the pharmacotherapeutic effects of medication while minimizing toxicity. By regularly measuring drug levels in the patient's blood, healthcare providers can ensure that drug concentrations remain within a therapeutic range. This is particularly important for medications with a narrow therapeutic index, where small changes in dosage can lead to ineffective treatment or harmful side effects.

Implementing therapeutic drug monitoring allows clinicians to adjust dosages based on individual patient responses, considering factors such as metabolism, age, weight, and comorbid conditions. Ultimately, this practice enhances the effectiveness and safety of drug therapy by ensuring that patients receive the most appropriate dosing for their specific needs.
