Coating

Biopharmaceutical Coating. Most tablets are coated after being pressed. Tablet coatings must be stable and durable enough to survive handling. They must not cause tablets to stick together during the coating process, and must follow the contours of embossed characters on tablets. Coatings are used for tablets that have an unpleasant taste. A smooth finish makes large tablets easier to swallow. Tablet coatings also extend the shelf-life of tablets that are sensitive to moisture. If a tablet is sensitive to acid, or is irritating to the stomach lining, an enteric coating can be used, which resists stomach acid and dissolves in the high pH of the intestines. Coatings are often chosen to control the rate of dissolution of the drug in the gastro-intestinal tract.
