What is the Origin of Oral Hormones?

The term is descriptive and pharmacological, combining "oral," derived from the Latin os (mouth), and "hormones," referring to the body's chemical messengers. The development of orally active steroid hormones was a significant breakthrough in the mid-20th century, greatly expanding the accessibility of hormone therapy. This route is defined by the initial passage through the digestive and hepatic systems.

What is the Mechanism of Oral Hormones?

Upon ingestion, the hormone is absorbed into the portal circulation and transported directly to the liver, where it undergoes first-pass metabolism. This process can lead to significant breakdown of the hormone itself and the production of various active and inactive metabolites. For some hormones, this hepatic exposure can alter the synthesis of liver proteins, such as sex hormone-binding globulin (SHBG) or clotting factors, leading to distinct systemic effects compared to non-oral administration.

Oral Hormones

Meaning

Oral Hormones are synthetic or bio-identical hormone preparations designed to be administered by mouth, where they are absorbed through the gastrointestinal tract. This route of administration is convenient but subjects the hormone to first-pass metabolism in the liver before reaching systemic circulation. The type of hormone, such as oral contraceptives or oral estradiol, and its chemical structure determine the extent of hepatic modification and the resulting metabolic profile. Clinicians must consider this unique pharmacokinetic profile when prescribing oral formulations compared to transdermal or injectable routes.
