What Is a Buccal Tablet?

A buccal tablet is a solid medicine designed to be placed between the gum and inner cheek. It dissolves or adheres there so the drug can act locally or pass through the buccal mucosa into the bloodstream. Buccal absorption can reduce or bypass some gastrointestinal and first-pass liver exposure. The tablet should be used according to its product-specific placement and handling instructions.

What Are Buccal Tablets Used For?

Buccal tablets are used when a medicine needs local action in the mouth or absorption through the cheek lining. Products can contain medicines for pain, nausea, oral fungal infection, hormone treatment, or other conditions. The route can be useful when swallowing is difficult or when gastrointestinal breakdown and first-pass metabolism would reduce drug exposure. Not every medicine can cross the buccal mucosa effectively.

How Do Buccal Tablets Work?

Saliva moistens the tablet and allows the active ingredient to dissolve. The drug then moves across the inner cheek lining and can enter the local tissues or venous circulation. Systemically absorbed drug can reach the bloodstream without first traveling through the hepatic portal vein. Absorption is affected by the formulation, saliva, contact time, mucosal health, and drug properties.

How Is a Buccal Tablet Taken?

The tablet is placed in the exact location stated in the product instructions, commonly between the upper gum and cheek. It is usually allowed to dissolve without chewing, crushing, sucking, or swallowing it whole. Some products should be alternated between sides of the mouth or used after the mouth is moistened. Eating, drinking, touching, or replacing a tablet must follow the medicine's specific directions.

What Are the Side Effects and Precautions?

Possible local effects include mouth pain, irritation, redness, ulcers, altered taste, or gum discomfort. A tablet that is swallowed early can produce reduced, delayed, or otherwise different absorption. Systemic side effects and interactions depend on the active drug and can be serious for potent medicines. Patients should keep buccal tablets away from children and follow exact disposal and emergency instructions for the prescribed product.

Frequently Asked Questions About Buccal Tablets

Is a buccal tablet swallowed like a regular tablet?

No. It is normally held between the gum and cheek so it can dissolve and release medicine at that site. Swallowing it whole can change how well or how quickly the drug works.

Is buccal administration the same as sublingual administration?

No. Buccal medicine is placed against the cheek, while sublingual medicine is placed under the tongue. Absorption rate, formulation, and instructions can differ.

Can a buccal tablet be chewed or crushed?

Not unless the product instructions specifically allow it. Chewing or crushing can alter drug release, absorption, local exposure, and safety.

What should happen if a buccal tablet falls out?

The correct action depends on how long the tablet was in place and the product being used. Patients should follow the medication guide or contact a pharmacist rather than automatically taking another full dose.
