What is the Origin of Dosing Inaccuracy?

This is a practical term rooted in the clinical principles of pharmacokinetics and pharmacodynamics, which govern the relationship between drug concentration and physiological effect. The concept arises from the necessity for fidelity in drug delivery to ensure predictable clinical outcomes. It highlights the real-world challenges in compounding, measurement, and patient self-administration that can undermine a scientifically calculated treatment regimen.

What is the Mechanism of Dosing Inaccuracy?

Inaccuracy can stem from various points in the therapeutic chain, including volumetric errors during reconstitution, variability in absorption across different administration routes, or patient non-adherence to the protocol. A sub-therapeutic dose fails to achieve the necessary receptor saturation to trigger the desired biological response, while an excessive dose increases the risk of receptor overstimulation or systemic side effects. The mechanism is a failure to achieve the requisite plasma concentration for optimal physiological modulation.

Dosing Inaccuracy

Meaning

Dosing Inaccuracy is the measurable difference between the quantity of a therapeutic agent prescribed or intended for administration and the amount actually delivered to the patient. This deviation, whether an under- or over-dose, directly impacts the drug’s concentration at the site of action, potentially compromising the therapeutic window. Precision in dosing is a non-negotiable clinical requirement, especially for hormones and peptides with narrow margins between efficacy and toxicity.
