Which method involves placing a tablet under the tongue to dissolve?

The method of placing a tablet under the tongue to dissolve is known as sublingual administration. This route is effective because it allows for rapid absorption of the medication directly into the bloodstream through the mucous membranes in the mouth. When a tablet is placed sublingually, it bypasses the digestive system and first-pass metabolism in the liver, leading to quicker therapeutic effects.

In contrast, the buccal method involves placing a tablet between the gums and the inner lining of the cheek, allowing the medication to dissolve and be absorbed through the buccal mucosa. While lozenges are designed to dissolve in the mouth and can deliver medication orally, they are not specifically placed under the tongue. Chewable tablets require mastication before swallowing, thus not aligning with the sublingual method. Therefore, sublingual is the appropriate choice in this context, focusing on its distinct absorption mechanism.
