Preparations (often in the form of a powder) containing the four enzymes (see ENZYME) trypsin, chymotrypsin, lipase, and amylase, which continue the digestion of foods started in the stomach (see PANCREAS – Functions; DIGESTION). They are given by mouth for the relief of pancreatic deficiency in conditions such as pancreatitis (see PANCREAS, DISORDERS OF) and CYSTIC FIBROSIS. Pancreatin is also used for the preparation of pre-digested, or so-called peptonised, foods, such as milk and some starchy foods.
