It is possible to cure gastric sinusitis completely by taking acid-suppressing drugs such as omeprazole, gastric mucosa-protecting drugs such as Rebapatide, and antibiotic drugs such as clarithromycin. Acid-suppressing drugs such as omeprazole and cimetidine can first be used in the treatment of gastric sinusitis, which can reduce the amount of gastric acid secreted by the secretory glands on the stomach wall, so as to minimize the erosion of gastric mucosa by gastric acid. Then you can take gastric mucosal protection drugs such as Rebapent, which can promote the healing of gastric mucosal damage caused by inflammation. In addition, omeprazole, bismuth pectin combined with antibiotics such as clarithromycin, amoxicillin, etc., can eliminate the pathogens that cause gastric sinusitis such as Helicobacter pylori, etc., and promote the recovery of gastric sinusitis. The above drugs need to be under the guidance of a physician, not blindly self-medication.
