What is the Origin of Non-Pulsatile Dosing?

This dosing principle is a direct application of pharmacokinetic and pharmacodynamic research, distinguishing between the biological requirements for pulsatile signaling, such as in the hypothalamic-pituitary axis, and the need for constant basal levels in peripheral tissue replacement. The term highlights a deliberate deviation from the natural pulsatile release pattern for specific therapeutic benefits.

What is the Mechanism of Non-Pulsatile Dosing?

The delivery system, typically a transdermal patch, gel, or subcutaneous implant, is engineered for zero-order release kinetics, ensuring a constant amount of drug is released per unit of time. This mechanism bypasses the peaks and troughs, preventing the acute receptor downregulation that can occur with high-amplitude fluctuations. The result is a consistent, non-stimulatory, and physiologically stable concentration of the hormone at the cellular level.

Non-Pulsatile Dosing

Meaning

Non-Pulsatile Dosing is a pharmaceutical delivery strategy in hormonal therapy that aims to maintain a steady, relatively flat concentration of the therapeutic agent in the bloodstream over the dosing interval. Unlike pulsatile release, which mimics the body’s natural, intermittent bursts of hormone secretion, this method provides a continuous, sustained presence of the hormone. This technique is often preferred when the clinical goal is to achieve constant receptor saturation or when the natural pulsatility is not the desired therapeutic effect.
