Which medication can relieve vomiting caused by bile?

Generally, vomiting of yellow bile is commonly caused by insufficient gastrointestinal motility, bile reflux, gastrointestinal infections, and other factors. It often occurs in conditions such as bile reflux gastritis and acute gastroenteritis. Patients may follow medical advice to use medications such as domperidone tablets, omeprazole enteric-coated capsules, aluminum carbonate magnesium chewable tablets, metoclopramide tablets, and racemic anisodamine tablets to alleviate symptoms. Detailed explanations are as follows:

1. Domperidone Tablets

Domperidone is a prokinetic agent that enhances the tone of the lower esophageal sphincter, promotes gastric motility, accelerates the emptying of food and bile from the stomach, and reduces bile reflux into the stomach and esophagus. This helps alleviate vomiting caused by bile reflux and is suitable for vomiting of yellow bile due to insufficient gastrointestinal motility.

2. Omeprazole Enteric-Coated Capsules

Omeprazole is a proton pump inhibitor that suppresses acid secretion from gastric parietal cells, reduces gastric acidity, and minimizes irritation of the gastric mucosa caused by both stomach acid and bile. It also alleviates gastric discomfort caused by bile reflux and indirectly reduces vomiting. This medication is suitable for vomiting of yellow bile associated with bile reflux gastritis.

3. Aluminum Carbonate Magnesium Chewable Tablets

Aluminum carbonate magnesium is an antacid and gastric mucosal protective agent. It neutralizes excess gastric acid and forms a protective layer on the surface of the gastric mucosa to prevent damage from bile. It can also bind bile acids, reducing irritation to the gastrointestinal tract and alleviating vomiting symptoms. It is suitable for gastric discomfort and vomiting caused by bile reflux.

4. Metoclopramide Tablets

Metoclopramide has a central antiemetic effect, inhibiting the vomiting center in the medulla oblongata. It also promotes movement of the esophagus and stomach, accelerating gastric emptying and reducing bile stasis and reflux, thereby alleviating vomiting of yellow bile. It is suitable for nausea and vomiting caused by various factors, including vomiting related to bile reflux.

5. Racemic Anisodamine Tablets

Racemic anisodamine is an anticholinergic drug that relieves gastrointestinal smooth muscle spasms. It helps alleviate vomiting caused by impaired bile drainage and reflux due to gastrointestinal spasms, and also reduces abdominal pain caused by gastrointestinal smooth muscle spasms. It is suitable for vomiting of yellow bile accompanied by gastrointestinal spasms.

It is important to maintain good daily habits, avoid overeating, and limit consumption of spicy, greasy, and cold foods such as chili peppers, fried foods, and ice cream. Avoid lying down immediately after meals; light walking can help reduce bile reflux. If vomiting is frequent or accompanied by abdominal pain, fever, or other symptoms, seek medical attention promptly to identify the underlying cause.
