Which tablet form consists of an internal core surrounded by a coating in a dry coating process?

• A. Film Coated Tablets
• B. Enteric Coated Tablets
• C. Gelatin Coated Tablets
• D. Compression Coated Tablets

Answer: (D)

Compression-coated tablets are formed by surrounding a pre-made core with a coating material and then compressing again to trap that coating around the core. This coating is built up in a dry process, meaning no solvent or liquid film is sprayed and dried. The result is a tablet with an inner core and an outer coat created purely by compression.

Other forms rely on liquid coating steps: film-coated and enteric-coated tablets get a thin polymer film by spraying a coating solution or dispersion and drying it, while gelatin-coated tablets use a gelatin-based coating that dries after dipping or spraying. These involve wet coating methods, unlike the dry compression approach.
