Gastro-esophageal reflux is a term that defines the reverse flow of acid gastric contents into the esophagus. On the other hand, alkaline reflux occurs in the case when alkaline intestinal contents enter the esophagus. The aim of the study was to examine the pharmaceutical properties of gels for the treatment of gastro-esophageal reflux, covering the mucosa, allowing prolonged contact with the esophageal mucosa. Formulations containing the PVP K-30 showed the lowest pH, which is an important feature and can be used in the treatment of advanced alkaline reflux. Gels containing PVP K-90 and chitosan can be used in the treatment of acid reflux. The addition of chitosan significantly increased the dynamic viscosity of the tested gels. The study of the work of adhesion showed the effect of PVP K-30 and PVP K-90 and their concentration on the value of the work of adhesion. The presented studies have shown that it is possible to obtain gels with high adhesion to the esophageal mucous membrane.
