Evaluation of the Efficacy and Safety of Gelsectan in the Treatment of Diarrhea-predominant Irritable Bowel Syndrome at University Medical Center Ho Chi Minh City, Vietnam: a Randomized, Open-label Clinical Trial
This clinical study aims to investigate the effectiveness and safety of Gelsectan, a treatment containing xyloglucan, in adults diagnosed with diarrhea-predominant irritable bowel syndrome (IBS-D) in Vietnam. IBS-D is a common digestive disorder that causes frequent diarrhea along with abdominal pain and bloating, significantly affecting patients' daily life and wellbeing. The main goal of the study is to determine whether Gelsectan can reduce the severity of symptoms such as diarrhea, abdominal discomfort, and bloating, and improve patients' quality of life. Participants will be randomly assigned to receive either Gelsectan alone, Gelsectan combined with an antispasmodic medication, or antispasmodic medication alone. The treatment will last for two months, with regular monitoring of symptom changes and any side effects. The investigators hypothesize that Gelsectan treatment will lead to better symptom relief and quality of life compared to standard antispasmodic treatment. The study will also carefully observe the safety profile of Gelsectan during the treatment period. Results from this study will provide important information about the potential benefits and risks of Gelsectan for Vietnamese patients with IBS-D and may contribute to improving treatment options for this condition in Vietnam.
