Therapeutic Range

Last Updated: June 30, 2019

Definition - What does Therapeutic Range mean?

Therapeutic range is the range of drug levels in the blood of a patient in which a drug has the desired effects upon the body. It relates to a quantitative benchmark associated to proper dosage levels of prescription medications within the serum or plasma of the bloodstream and the distinct reactions that can happen between toxicity (overdose) and ineffective treatment (under-dose) of the patient. Therapeutic range is a standard metric in the administration of prescription drugs that have a relatively narrow window in terms of accommodating a patient’s pharmacological needs while accounting for any changeable factors to occur in dosage analytics.

WorkplaceTesting explains Therapeutic Range

Therapeutic range defines the quantitative measurement of a prescription medication’s dosage level by regularly evaluating and correlating distinctions between the efficacy and toxicity of the concentration of a drug within the serum or plasma of the bloodstream.

The administration of medications to all patients requires necessary observation through repeated checkups at designated intervals by a physician to ascertain whether a current dosage provides conducive effects within the standardized therapeutic range model.

Since many drugs have a narrow window or range varying between toxicity and pharmacological treatment, the risk-to-benefits ratio demands monitoring and occasional adjustment to prescription dosages to optimize therapeutic results in the patient.
