Which dosage form is applied to a body surface?

• A. Buccal tablets
• B. Topical
• C. Capsules
• D. Lozenges

Answer: (B)

Topical dosage forms are applied directly to the skin or mucous membranes to act locally at the site of contact. This category includes creams, ointments, gels, lotions, and patches—recipes designed for surface application and local effect rather than for swallowing. The other options involve forms meant for internal use or dissolution in the mouth: capsules are taken by mouth and swallowed; lozenges dissolve in the mouth to release medication there or be absorbed; buccal tablets are placed in the cheek to release drug for absorption through the buccal mucosa. Thus, when a dosage form is applied to a body surface for local action, it is considered topical.
