The IO route of fluid and medication administration is an alternative to the preferred intravascular route when the latter cannot be established promptly in emergent situations. Intraosseous infusions are used when people have compromised intravenous access and need immediate delivery of life-saving fluids and medications.
Methods of administration include oral, sublingual (dissolving the drug under the tongue), and rectal. Parenteral administration is via a peripheral or central vein. [1] In pharmacology, the route of drug administration is important because it affects drug metabolism, drug clearance, and thus dosage. The term is from Greek enteros 'intestine'.
When the topical drug molecules transport via the paracellular route, it needs to travel across the stratum corneum, which is a highly fat region, but between the cells. [9] [1] On the other hand, the topical drug molecules may travel through the transcellular route. This route allows molecules to be transported via the cell.

Buccal administration may provide better bioavailability of some drugs and a more rapid onset of action compared to oral administration because the medication does not pass through the digestive system and thereby avoids first pass metabolism. [1] Drug forms for buccal administration include tablets and thin films.
The sublingual route may also be used for vaccines against various infectious diseases. Thus, preclinical studies have found that sublingual vaccines can be highly immunogenic and may protect against influenza virus [4] [5] and Helicobacter pylori, [6] but sublingual administration may also be used for vaccines against other infectious diseases.
