Core Tip

Core Tip: Irritable bowel syndrome is a common functional gastrointestinal disorder characterized by recurrent abdominal pain associated with altered bowel habits. Treatment options are limited and often inadequate, which leads to dissatisfaction among patients receiving standard medical care. Our study showed that 4 weeks of daily treatment with GASTRAP® DIRECT, a class IIa medical formulation containing a combination of chitin-glucan and simethicone, is well tolerated and rapidly effective in reducing abdominal pain, bloating, abdominal distension, and flatulence with an improvement of stool consistency and defecatory disorders.
