What is "therapeutic range"?

The concept of "therapeutic range" refers to the concentration of a drug in the bloodstream that achieves the desired therapeutic effects without causing toxicity. It is critical for healthcare providers to understand this range because it helps ensure that patients receive medication at levels that are both safe and effective. If the concentration of the drug falls below the therapeutic range, the medication may not provide the intended benefit, leading to insufficient treatment. Conversely, if the concentration exceeds this range, there is a risk of toxicity, which can lead to harmful side effects or serious adverse reactions.

Understanding the therapeutic range is essential for medication management, as it plays a key role in dosing adjustments and monitoring patients’ responses to medications. Maintaining drug levels within this range maximizes therapeutic effects while minimizing the risk of harm, which is a central responsibility for certified medication technicians.
