Pancrelipase delayed-release capsules (Creon, Pancreaze, Pertzye, Ultresa, Zenpep) are used to improve digestion of food in children and adults who do not have enough pancreatic enzymes (substances needed to break down food so it can be digested) because they have a condition that affects the pancreas (a gland that produces several important substances including enzymes needed to digest food) such as cystic fibrosis (an inborn disease that causes the body to produce thick, sticky mucus that may clog the pancreas, the lungs, and other parts of the body), chronic pancreatitis (swelling of the pancreas that does not go away), or a blockage in the passages between the pancreas and the intestine. Pancrelipase delayed-release capsules (Creon, Pancreaze, Zenpep) are also used to improve digestion of food in infants who do not have enough pancreatic enzymes (substances needed to break down food so it can be digested) because they have cystic fibrosis or another condition that affects the pancreas. Pancrelipase delayed-release capsules (Creon) are also used to improve digestion in people who have had surgery to remove all or part of the pancreas or stomach. Pancrelipase tablets (Viokace) are used along with another medication (proton pump inhibitor; PPI) to improve digestion of foods in adults who have chronic pancreatitis or who have had surgery to remove the pancreas. Pancrelipase is in a class of medications called enzymes. Pancrelipase acts in place of the enzymes normally made by the pancreas. It works to decrease fatty bowel movements and to improve nutrition by breaking down fats, proteins, and starches from food into smaller substances that can be absorbed from the intestine.
