How to choose medication for indigestion?

There are two types of indigestion causes, one is decreased gastrointestinal motility, and the other is decreased secretion of digestive enzymes, which is why the elderly are prone to indigestion. Commonly used drugs include gastrointestinal motility drugs, such as domperidone, and various digestive enzymes, such as pepsin, amylase, pancreatin, dry yeast, etc., which are often made into compounds. The selection of digestive enzymes is particular: firstly, products with high activity should be selected, preferably containing pancreatic enzymes; secondly, enteric-coated preparations should be selected to protect the pancreatic enzymes from being inactivated by gastric acid.
