The invention is directed to the use of a specific group of polysaccharides for reducing the symptoms of heartburn and gastro-oesophageal reflux disease. In addition, a pharmaceutical preparation is provided comprising a specific group of polysaccharides having a high hydration rate, a high viscosity, and a high stability at low pH. Such a preparation is particularly effective in reducing the symptoms of heartburn and/or gastro-oesophageal reflux disease, particularly when consumed in dry form.本發明係關於一特定多糖類群組用以降低胃灼熱及胃食道逆流疾病之症狀的用途。此外,提供一種藥學製劑,其包含具有高水合速率、高黏度及於低pH值下具有高穩定性之特定多糖類群組。此一製劑可特別有效地降低胃灼熱及/或胃食道逆流疾病之症狀,尤其是以乾形式食用時。
