Sublingual abbreviation?

Explanation:
Sublingual administration is abbreviated SL. This means the drug is placed under the tongue to dissolve and be absorbed quickly through the oral mucosa, bypassing the stomach and liver’s first-pass metabolism. That fast onset is why SL is used for certain medications, like nitroglycerin tablets for chest pain. The other abbreviations—IM for intramuscular, IV for intravenous, and IO for intraosseous—refer to injections or IV routes, not sublingual. Remembering SL specifically signals the sublingual route, which is about absorption under the tongue rather than through muscle or vein.
