What is the Origin of Therapeutic Ranges?

The concept of therapeutic range originated in clinical pharmacology and toxicology to guide drug dosing, but it has been widely adopted and refined in endocrinology and functional medicine. This shift recognizes that 'normal' laboratory values may not equate to 'optimal' functional health, particularly in the context of age-related hormonal decline. The establishment of these ranges requires continuous correlation between biochemical levels and patient-reported outcomes.

What is the Mechanism of Therapeutic Ranges?

Maintaining levels within the therapeutic range ensures that the target receptors are adequately saturated to elicit the desired biological response without causing receptor desensitization or systemic toxicity. For hormones, this means achieving a concentration that supports anabolic signaling and tissue function without triggering excessive negative feedback or promoting pathological cell proliferation. The mechanism is one of controlled, sustained pharmacological or physiological action.

Therapeutic Ranges

Meaning

Therapeutic Ranges are the clinically established concentration intervals for specific biochemical markers, including hormones, vitamins, or pharmacological agents, that are associated with maximizing clinical benefit and minimizing adverse effects in a given patient population. Unlike broad laboratory reference intervals, which simply reflect a statistically normal population, therapeutic ranges are specifically defined to achieve an optimal physiological outcome based on the patient’s individual health goals and clinical context. Precision medicine relies heavily on defining and maintaining these ranges.
