Sublingual in Latin literally means "under the tongue". However it actually refers to the route of administration in which some certain drugs enter directly into the blood stream, they enter the blood stream via the absorption under the tongue. These drugs include steroids, barbiturates and some common cardiovascular drugs. These also include some enzymes, certain minerals and vitamins.

The main principle behind the sublingual administration is very simple, when the mucous membrane or buccal mucosa comes in contact with a chemical, this results in the diffusion of epithelium that is beneath the tongue. This region of the tongue contains very high density of blood vessels. Due to the result of diffusion, the substances quickly enter the venous circulation.
