What does "subl" or "sl" stand for in medication administration?

The abbreviation "subl" or "sl" stands for "sub-lingual," which refers to the administration of medication under the tongue. This route allows for quick absorption of the medication into the bloodstream through the tissues in the mouth, bypassing the digestive system. This method is often used for medications that require rapid onset of action, as absorption directly into the circulation can occur almost immediately.

In contrast, the other options refer to different routes of medication administration, such as oral (by mouth), intramuscular (in the arm), and intravenous (into the vein), but they do not align with the definition and purpose of sublingual administration. Understanding these routes is crucial for proper medication management and ensuring effective patient care.
