Patients with reflux esophagitis and gastric erosion commonly use acid-suppressing drugs, gastric mucosal protective drugs, pro-dynamic drugs and antibiotic drugs. 1. Acid-suppressing drugs: patients with reflux esophagitis and gastric erosion are usually accompanied by excessive secretion of gastric acid. By taking acid-suppressing drugs, such as proton pump inhibitors (omeprazole, lansoprazole, etc.) and H2-receptor antagonists (ranitidine, famotidine, etc.), the secretion of gastric acid can be effectively inhibited, reducing the concentration of gastric acid in the stomach, and decreasing the irritation of the reflux and gastric acid on the gastric mucosa. 2. Mucosal protection drugs: such as bismuth potassium citrate, magnesium aluminum carbonate, etc., which can form a protective layer on the surface of the mucosa, relieve the corrosion of gastric acid on the esophagus and gastric mucosa, and reduce the symptoms of patients. 3. Prokinetic drugs: such as mosapride, domperidone, etc., can promote gastrointestinal peristalsis, accelerate the discharge of gastric acid from the stomach, alleviate the symptoms of reflux, and at the same time, reduce the damage caused by gastric acid to the esophagus and gastric mucosa. 4. antibiotic drugs: reflux esophagitis and gastric erosion of patients with Helicobacter pylori infection, the patient can take amoxicillin, clarithromycin, metronidazole and other antibiotics at the same time, for the eradication of Helicobacter pylori treatment.
