What is the Origin of Oral Delivery?

The term combines 'oral,' derived from the Latin os meaning mouth, with 'delivery,' referring to the process of conveying the active agent to its site of action. This route has been utilized since the earliest forms of medicine, but modern pharmaceutical science has dedicated considerable effort to formulating dosage forms that optimize absorption and stability. The discipline of biopharmaceutics rigorously studies the factors that influence the bioavailability of orally delivered compounds.

What is the Mechanism of Oral Delivery?

The mechanism involves a multi-stage process beginning with the disintegration of the dosage form and the dissolution of the active compound within the gastrointestinal fluids. The dissolved substance must then be absorbed across the intestinal epithelial lining into the portal vein. Crucially, before reaching the general circulation, the absorbed compound passes through the liver, where it is subjected to first-pass metabolism by hepatic enzymes, which can substantially reduce the systemic bioavailability of the active drug.

Oral Delivery

Meaning

Oral Delivery is the most common and patient-preferred route of drug and supplement administration, involving the ingestion of a substance by mouth with the intent of absorption via the gastrointestinal tract into the systemic circulation. While highly convenient and non-invasive, this method presents significant pharmacokinetic challenges, primarily due to the acidic environment of the stomach and the extensive first-pass metabolism that occurs in the liver. The ultimate therapeutic efficacy depends on the substance’s stability and its ability to traverse these biological barriers efficiently.
