“…This route enjoys the advantages that it allows facile access, there is a potential for a quick onset of activity, there is usually improved bioavailability, and it offers the possibility of circumvention of the hepatic first‐pass elimination that decreases blood concentrations of perorally administered drugs. Examples of pharmacologically active compounds that may benefit from sublingual administration include nitrates (nitroglycerin) for angina pectoris,1 angiotensin‐converting enzyme inhibitors (captopril) for hypertensive crises,2 antihistamines (cetirizine) for allergic reactions,3 opioids (morphine) for analgesia,4 and benzodiazepines (triazolam) as hypnotics 5. In general, the sublingual route of drug delivery enjoys great potential for the administration of emergency medications.…”
