Frequent regurgitation may be caused by gastritis, dyspepsia, gastrointestinal motility disorders, etc. It can be solved by using acid-suppressing drugs, gastrointestinal stimulants, mucosal-protecting drugs, and anticholinergics, such as omeprazole, domperidone, and bismuth potassium citrate. 1. Acid-suppressing drugs: mainly including proton pump inhibitors and Hâ‚‚ receptor antagonists, commonly used omeprazole, cimetidine, etc., such drugs can inhibit the secretion of gastric acid, thus alleviating the discomfort of regurgitation. 2. Gastrointestinal dynamics drugs: Domperidone, Mosapride and other drugs are commonly used to increase gastric dynamics and enhance gastric emptying, suitable for gastrointestinal dynamics disorders caused by regurgitation symptoms. 3. Mucosal protection drugs: bismuth potassium citrate, bismuth pectin and other drugs are commonly used, such drugs can form a protective film on the surface of the damaged mucous membrane to isolate the erosion of pepsin and other substances and relieve regurgitation symptoms. If there is any discomfort, it is necessary to improve the relevant examination under the guidance of the doctor to clarify the diagnosis and standardize the treatment, so as not to delay the condition.
