sublingual administration
Drug delivery method where medication is placed under the tongue for absorption through oral mucosa.
Full Definition
Sublingual administration is a route of drug delivery where medication is placed beneath the tongue and allowed to dissolve, enabling absorption through the rich vascular network of the oral mucosa directly into systemic circulation. This route bypasses first-pass hepatic metabolism and gastrointestinal degradation, often providing faster onset and more predictable bioavailability compared to oral administration. In psychopharmacology, sublingual formulations are available for certain benzodiazepines, antipsychotics, and opioid medications used for breakthrough symptoms or rapid intervention scenarios. Patient education about proper sublingual technique is essential for optimal drug absorption.
Usage
Usage note: Distinguish from buccal (cheek) administration; emphasize proper technique in patient instructions.
