Why Is Sublingual Enteral

Sublingual and buccal routes are indicated for medications with high first-pass metabolism that need to avoid clearance by the liver. For instance, nitroglycerin is cleared more than 90% during a single pass through the liver; therefore, it is given as a sublingual form.

Why is sublingual considered enteral?

Enteral/gastrointestinal Furthermore, some application locations often classified as enteral, such as sublingual (under the tongue) and sublabial or buccal (between the cheek and gums/gingiva), are taken up in the proximal part of the gastrointestinal tract without reaching the intestines.

What is the difference between enteral and parenteral routes of administration?

Enteral nutrition is administered through a feeding tube placed into the stomach or intestines. Parenteral nutrition is administered through a traditional intravenous (IV) line or via a central IV surgically placed during an outpatient procedure.
