Gastroesophageal reflux disease (GORD) is a common condition induced by unwarranted reflux of gastric and duodenal contents into the esophagus, and insufficient clearance of refluxate from it. Pharmaceutical formulations possessing raft‐forming capability offers an excellent alternative to conventional treatment options to treat uncomplicated GORD. These formulations typically contain a polymer, which performs distinctively upon contact with gastric acid and develops a foam‐like structure that can float on gastric contents. This review aims to feature research articles and patents that cover this topic. After undergoing a standardized literature search following preferred reporting items for systematic reviews and meta‐analyses guidelines, we have included 38 research articles and 18 patents describing the role of raft‐forming polymers in the treatment of GORD. This is a comprehensive review of formulation/testing of raft‐forming polymers. As expected, the majority of the studies focused on alginate; however, fewer studies have reported the use of pectin, xanthan gum, and raw psyllium fibers (husk). Moreover, it can be concluded from this comprehensive systematic review that a detailed characterization of raft‐forming formulations, type, and concentration of used active and inactive materials and different formulations factors are essential for the development of successful anti‐reflux raft‐forming formulations. © 2019 Wiley Periodicals, Inc.
