Which term refers to a semisolid preparation applied externally?

• A. Gavage
• B. Lozenge
• C. Suspension
• D. Ointment

Answer: (D)

This item tests understanding of topical semisolid dosage forms. An ointment is a semisolid preparation designed for external application to the skin or mucous membranes. Its greasy base stays on the surface, forming an occlusive film that helps retain moisture and deliver the active ingredient locally. By contrast, a lozenge is meant to dissolve in the mouth for local or systemic effects; a suspension is a liquid with dispersed solid particles; gavage refers to delivering substances via a tube into the stomach. Because it is specifically a semisolid product applied externally, the correct term is ointment.
