In case of gastric acid regurgitation, we usually take drugs to inhibit gastric acid secretion. Our common drugs are omeprazole, pantoprazole, lansoprazole, and rabeprazole. The best drug is Esomeprazole. If this drug is taken one tablet at a time, once a day, it can inhibit gastric acid secretion to treat acid regurgitation.? We can take another drug to protect the gastric mucosa. The drugs we commonly use are sucralfate, bismuth potassium citrate, etc. In addition to these, we can also take some traditional Chinese medicine, which has a very fast effect. One of the drugs is the h2 receptor antagonist.
