What is the Origin of Oral Micronized Progesterone?

The term combines "oral," indicating the route of administration, with "micronized," describing the particle size reduction process essential for bioavailability. "Progesterone" is derived from the Latin pro gestare, meaning "for bearing," reflecting its primary role in maintaining pregnancy. The micronization technique was developed to overcome the poor bioavailability of natural progesterone due to extensive first-pass metabolism in the liver.

What is the Mechanism of Oral Micronized Progesterone?

After oral ingestion, the micronized particles are absorbed into the portal circulation via the gastrointestinal tract. Due to the hepatic first-pass effect, a significant portion is rapidly metabolized into neuroactive metabolites, such as allopregnanolone, before entering the systemic circulation. The remaining progesterone and its metabolites then bind to progesterone receptors in target tissues, exerting effects such as endometrial protection, mood stabilization, and promotion of restful sleep.

Oral Micronized Progesterone

Meaning

Oral micronized progesterone is a bioidentical form of the hormone progesterone that has been mechanically processed into very fine particles to significantly enhance its absorption when administered by mouth. This specific formulation is used clinically to treat conditions related to progesterone deficiency, such such as menopausal symptoms, anxiety, and menstrual irregularities. It offers a route of administration that allows for systemic effects, including the crucial neuro-sedative effects mediated by its metabolites in the brain.
