Which tablets are meant to be placed under the tongue for absorption?

Sublingual tablets are specifically designed to dissolve and be absorbed directly into the bloodstream through the tissue under the tongue. This route allows for rapid absorption, bypassing the digestive system, and can lead to quicker onset of effects compared to oral tablets that must travel through the gastrointestinal tract.

The formulation of sublingual tablets allows them to rapidly disintegrate and release the medication to be absorbed sublingually, making them effective for drugs that require immediate action, such as nitroglycerin for angina relief.

Chewable tablets are meant to be chewed before swallowing, which aids in digestion but does not provide the expedited absorption that sublingual tablets do. Buccal tablets are placed between the gums and cheek for absorption through the buccal mucosa, while vaginal tablets are designed for insertion into the vagina, targeting localized effects rather than systemic absorption.
