Ask a question


Gastrointestinal protectants are a type of medication taken orally which serve to protect the digestive mucous membrane, a coating inside the gastrointestinal tract. They are used in the treatment of gastroesophageal reflux disease, or GERD, a condition associated with particularly unpleasant symptoms of acid reflux. Gastrointestinal protectants, also called alginates, create a protective barrier between an irritated, fragile lining and the different elements that could irritate it, such as various foods, digestive juices, and so on. They should be taken after a meal.
