Question 9

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

Buccal dosage forms are specifically designed to be placed against the inner cheek, allowing for absorption through the mucous membranes. This method facilitates direct entry into the bloodstream, bypassing the gastrointestinal tract.

A) in the rectum

This option is incorrect as buccal dosage forms are not intended for rectal administration. Rectal administration is associated with suppositories or enemas, which are designed for different absorption pathways and therapeutic purposes.

B) in the ear

This option is also incorrect because buccal dosage forms are not used in the ear. Ear medications typically come in the form of drops or ointments specifically formulated for otic use, not for mucosal absorption in the mouth.

C) against the cheek

This option is correct as buccal dosage forms are intended to be placed against the cheek. This position allows the drug to dissolve and be absorbed directly through the buccal mucosa, providing a rapid onset of action.

D) under the tongue

While this option refers to sublingual dosage forms, it is incorrect in the context of buccal medications. Sublingual forms are placed under the tongue for absorption, which differs from the placement of buccal forms against the cheek.

Conclusion

The correct answer is C, as buccal dosage forms are specifically designed for placement against the cheek, facilitating absorption through the buccal mucosa. All other options either refer to inappropriate administration routes or other dosage forms, highlighting the unique characteristics of buccal medications.
