Sublingual administration is a method of delivering medication by placing it under the tongue. This route allows the drug to dissolve and be absorbed directly into the bloodstream through the mucous membranes, bypassing the digestive system. This can lead to faster onset of action compared to oral administration. This method is often used for certain types of medications, such as nitroglycerin for chest pain or hormones like testosterone. Sublingual tablets or films are designed to dissolve quickly, making them convenient for patients who may have difficulty swallowing pills.
