Question 37

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

Buccal dosage forms are designed to be placed against the inner lining of the cheek, allowing for absorption through the oral mucosa. This method facilitates direct entry into the bloodstream, bypassing the digestive system.

A) in the rectum.

This option is incorrect because the rectum is not a buccal site. Rectal administration is a separate route of drug delivery known as rectal dosage form, which is intended for medications that are absorbed through the rectal mucosa.

B) in the ear.

Placing a drug in the ear is not associated with buccal dosage forms. Ear administration pertains to otic formulations that target conditions within the ear canal, and does not involve the buccal cavity.

C) against the cheek.

This is the correct option as buccal dosage forms are specifically designed to be placed against the cheek. This location provides a suitable environment for absorption into the systemic circulation via the mucosal tissues.

D) under the tongue.

While sublingual dosage forms are placed under the tongue for absorption, this is not the same as buccal forms. Sublingual administration targets the area beneath the tongue, which is distinct from the buccal area against the cheek.

Conclusion

The correct answer is option C, as buccal dosage forms are specifically formulated for placement against the cheek to enable effective absorption. Options A, B, and D pertain to different routes of drug administration that do not align with the characteristics of buccal dosage forms, confirming that only option C correctly addresses the question.
