Which coating results in a thin polymer film forming a skin-like layer on the tablet surface?

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

Answer: (D)

Film coating creates a very thin, continuous polymer layer that sits on the tablet surface like a skin. This coating is applied as a solution or suspension and dried to form a smooth, uniform film, adding minimal thickness while protecting or masking taste. This distinguishes it from thicker coatings like enteric (which resists stomach acid and dissolves later), compression coatings (which add a substantial outer layer by compression), and gelatin coatings (which form a gelatin outer shell often for masking or encapsulation).
