Question 54

A drug in buccal dosage form would be placed against the cheek.

Buccal dosage forms are designed to be placed between the gum and the inner lining of the cheek, allowing for absorption directly into the bloodstream. This method provides a convenient and effective route for drug delivery.

A) in the rectum.

Placing a drug in the rectum refers to rectal dosage forms, which are specifically designed for that route of administration. This is not applicable for buccal dosage forms, which are intended for absorption in the oral cavity, not the rectal area.

B) in the ear.

Administering medication in the ear pertains to otic dosage forms, which are formulated for use in the ear canal. This option is unrelated to buccal administration, which focuses on the mucosal surfaces of the mouth.

C) against the cheek.

This option correctly identifies the appropriate placement for buccal dosage forms. These forms are designed to dissolve and be absorbed through the buccal mucosa, which is the inner lining of the cheek, facilitating rapid systemic absorption.

D) under the tongue.

While placing a drug under the tongue refers to sublingual dosage forms, which also allow for quick absorption, it differs from buccal forms. Sublingual administration targets the area beneath the tongue rather than the cheek, making this option incorrect for buccal dosage forms.

Conclusion

The correct placement for a buccal dosage form is against the cheek, where it can effectively dissolve and be absorbed through the mucosal membrane. Options A, B, and D describe different routes of administration that do not align with the buccal method, reinforcing that C is the definitive answer.
