Ointment, semisolid preparation applied externally?

• A. Gavage
• B. Placebo
• C. Ointment
• D. Gtt.

Answer: (C)

An ointment is a semisolid preparation intended for external application to the skin or mucous membranes. It’s typically oil-based and stays on the surface, forming an occlusive layer that helps keep moisture around the treated area and allows gradual drug absorption. Gavage means delivering substances by mouth through a tube into the stomach, which is not topical. Gtt stands for drops, a liquid form given as eye/ear/nose drops. Placebo is an inert substance used as a control and isn’t defined by being a semisolid topical preparation. So the semisolid preparation applied externally is an ointment.
