Western medicines for flatulence include domperidone, mosapride, bifidobacterium tetragonum tablets, thioglycollate, and cimetidine. Reduced gastrointestinal motility and indigestion can lead to flatulence in patients. Domperidone can effectively improve gastric flatulence by improving gastrointestinal motility, enhancing intestinal peristalsis, promoting gastric emptying, and improving digestion and absorption. Mosapride can enhance gastrointestinal peristalsis, improve gastrointestinal function and improve the symptoms of flatulence and indigestion by stimulating cholinergic neurons in gastrointestinal tract and promoting the release of acetylcholine. Bifidobacterium bifidum tetragonum tablets can inhibit intestinal pathogenic bacteria, balance the intestinal flora, promote the recovery of gastrointestinal function, improve gastrointestinal motility, enhance intestinal peristalsis, thereby improving digestion and absorption function and improving gastric flatulence. Part of chronic gastritis due to increased secretion of gastric acid can also lead to flatulence, the use of thioglycollate, cimetidine, etc., can protect the gastric mucosa, inhibit the secretion of gastric acid, improve the gastric flatulence.
