Among the diseases of the digestive tract, gastro-oesophageal reflux is one of the most troublesome ailments. It is estimated that in highly developed countries, reflux symptoms occur in about 5%-10% of people every day. It has also been found that about 20% of people experience such symptoms once a week. The incidence of this disease increases with age, regardless of gender. The aim of the study was to investigate the physicochemical properties of gels intended for the protection of the oesophageal mucosa. Preparations containing 3.0% pectin showed the lowest pH. These gels can be used in the treatment of advanced alkaline reflux. The addition of chitosan to all tested gels increased their pH and dynamic viscosity. The texture tests showed the effect of pectin concentration on the adhesion work of the tested gels.

Reflux disease is one of the most frequently diagnosed conditions in developed countries. The problem is both the acidic content of the stomach and the alkaline content of the intestines. In each case, the oesophageal mucosa is destroyed. I analysed hydrogels that prevent irritation of the oesophageal mucosa. Specifically, I investigated the effect of chitosan and sodium alginate on the properties of gels protecting the oesophagus. Gels containing chitosan and 1.0% sodium alginate can be used to treat advanced alkaline reflux. The addition of chitosan to all the tested gels increased their pH and dynamic viscosity, making it possible to neutralise acid reflux. Texture studies showed the influence of chitosan and sodium alginate on the adhesiveness of the tested gels.

The troublesome symptoms of gastro-oesophageal reflux disease are a serious health, medical, and social problem for patients. The main problem is gastro-oesophageal acid reflux. In this study, I investigated hydrogels that could prevent the destruction of the oesophageal mucosa. I investigated the effect of chitosan and poloxamer 407 on the protective properties of gels. The addition of chitosan to all the tested gels increased their pH and dynamic viscosity. Preparations containing 25% poloxamer 407 showed the highest pH. Texture tests showed the effect of the poloxamer concentration on the adhesion performance of the tested gels. The findings suggest that the gels can be used to treat advanced acid reflux.

The incidence of reflux disease increases with age, regardless of gender. This disease is diagnosed more often in highly developed countries. In addition to acidic reflux, the discharge of alkaline intestinal contents into the oesophagus is a major problem. This study was undertaken to examine whether hydrogels prevent irritation of the oesophageal mucosa. The aim was to investigate the influence of chitosan and hydroxypropylmethylcellulose on the properties of chitosan-containing gels. Preparations containing 4.0% hydroxypropylmethylcellulose showed the lowest pH. These gels could be used to treat advanced alkaline reflux. The addition of chitosan to all tested gels increased their pH and dynamic viscosity. The texture tests showed the effect of the hydroxypropylmethylcellulose concentration on the adhesion work of the tested gels.

Gastro-oesophageal reflux disease is a serious social problem that affects every sphere of life. The quality of life of people with this disease is reduced due to the presence of troublesome symptoms, which translates into reduced work efficiency and vitality. The major problem is acidic gastro-oesophageal reflux. This study was undertaken to examine whether hydrogels prevent irritation of the oesophageal mucosa. The aim was to investigate the influence of chitosan and carboxymethylcellulose sodium salt on the protective properties of prepared gels in the treatment of acid reflux. The addition of chitosan to all tested gels increased their pH and dynamic viscosity. Preparations containing 0.3% carboxymethylcellulose sodium salt showed the highest pH. The texture tests showed the effect of carboxymethylcellulose sodium salt concentration on the adhesion work of the tested gels. These gels could be used in the treatment of advanced acid reflux.
