An enteric coating is a polymer barrier applied to oral medication that prevents its dissolution or disintegration in the gastric environment. [1] This helps by either protecting drugs from the acidity of the stomach, the stomach from the detrimental effects of the drug, or to release the drug after the stomach (usually in the upper tract of the intestine).

For most coated tablets, a cellulose ether hydroxypropyl methylcellulose (HPMC) film coating is used which is free of sugar and potential allergens. Occasionally, other coating materials are used, for example synthetic polymers, shellac, corn protein zein or other polysaccharides. Capsules are coated with gelatin.
Buccal tablets offer many advantages over other solid dosage forms also intended for oral administration (e.g. enteric-coated tablets, chewable tablets, and capsules). Buccal tablets can be considered in patients who experience difficulty in swallowing, since these tablets are absorbed into the blood stream between the gum and cheek.
