What is the Origin of Oral Progesterone?

The term is derived from clinical pharmacology and endocrinology. 'Oral' refers to the route of administration via the mouth, and 'progesterone' comes from the Latin pro (for) and gestare (to bear), referencing its role in gestation. The micronization technique represents a pharmaceutical innovation to overcome poor oral absorption.

What is the Mechanism of Oral Progesterone?

Upon ingestion, oral progesterone is absorbed and undergoes significant first-pass metabolism in the liver, which generates various active and inactive metabolites, including allopregnanolone. This metabolic profile contributes to its systemic effects, particularly its notable anxiolytic and sedative properties mediated through interaction with GABA receptors in the central nervous system. It also binds to progesterone receptors in target tissues like the endometrium, providing necessary hormonal signaling.

Oral Progesterone

Meaning

A form of the steroid hormone progesterone administered by mouth, typically formulated as micronized progesterone to enhance its absorption and bioavailability in the gastrointestinal tract. Unlike synthetic progestins, oral micronized progesterone is chemically identical to the hormone naturally produced by the corpus luteum. This route of administration is frequently utilized in hormone replacement therapy for its systemic effects, including endometrial protection and neuroendocrine benefits. Its unique metabolic profile distinguishes it clinically from other progesterone forms.
