What is the Origin of Progesterone Pharmacokinetics?

This term combines the endogenous steroid hormone progesterone with pharmacokinetics, a Greek-derived word meaning "drug movement." The need for this study arose because natural progesterone is poorly bioavailable when administered orally due to extensive first-pass hepatic metabolism. Understanding its movement is essential for therapeutic use.

What is the Mechanism of Progesterone Pharmacokinetics?

The route of administration dictates the initial absorption and metabolic fate of the hormone. Oral micronized progesterone undergoes significant first-pass metabolism in the liver, yielding numerous neuroactive metabolites. In contrast, transdermal or vaginal administration allows for direct, sustained systemic or local delivery, bypassing the hepatic portal system and resulting in a different concentration-time curve and metabolite profile.

Progesterone Pharmacokinetics

Meaning

Progesterone Pharmacokinetics is the study detailing the absorption, distribution, metabolism, and excretion (ADME) of administered progesterone within the human body. This specialized field examines how the body handles the hormone over time, providing critical data for determining optimal dosing, frequency, and administration routes in clinical practice. The pharmacokinetic profile is highly dependent on the formulation utilized.
