What are the three best medications for treating intestinal gas?

Under normal circumstances, intestinal gas is caused by improper diet, indigestion, imbalance of intestinal flora, and other factors. The treatment of intestinal distension may involve medications such as Domperidone tablets, Mosapride Citrate tablets, Simethicone emulsion, Lactasin tablets, and Jianwei Xiaoshi tablets under a doctor's guidance. If any abnormalities occur, prompt medical attention is recommended. Detailed explanations are as follows:

1. Domperidone Tablets: Domperidone is a gastrointestinal motility enhancer. It stimulates nerve cells in the gastrointestinal wall to release acetylcholine, indirectly enhancing the contraction of gastrointestinal smooth muscles, thereby accelerating food transit through the digestive tract, effectively improving delayed gastric emptying and relieving feelings of fullness.

2. Mosapride Citrate Tablets: Mosapride citrate is a prokinetic agent for the digestive tract. It selectively activates 5-HT4 receptors, promoting the release of acetylcholine, thus enhancing motility in the upper digestive tract, accelerating gastrointestinal peristalsis, reducing the burden on the digestive system, and effectively relieving gas accumulation, bloating, and related symptoms.

3. Simethicone Emulsion: Simethicone emulsion is primarily used to treat discomfort caused by excessive gas accumulation in the gastrointestinal tract, such as bloating. It inhibits gas formation and promotes gas expulsion from the gastrointestinal tract. Its main component, dimethicone, mixes with gastrointestinal mucus to form a protective layer that reduces gas formation and facilitates gas expulsion, thereby effectively relieving intestinal gas.

4. Lactasin Tablets: Lactasin in these tablets selectively acts on the human intestine, helping to inhibit the excessive growth of harmful bacteria and alleviating gas symptoms caused by fermentation.

5. Jianwei Xiaoshi Tablets: Primarily used for treating feelings of fullness caused by functional dyspepsia. Ingredients such as Pseudostellaria heterophylla, tangerine peel, hawthorn, and roasted barley promote spleen and stomach function, improve digestion, and enhance secretion of digestive fluids and gastrointestinal peristalsis.

All the above medications should be used under the guidance of a doctor to ensure safe and effective treatment. During medication, patients should follow medical advice, monitor drug reactions, and seek timely medical help if any adverse effects occur.
