Patients with atrophic gastritis can take metronidazole dispersible tablets, clarithromycin capsules, omeprazole magnesium tablets, bismuth citrate potassium granules, atropine sulfate tablets and other types of drugs. Helicobacter pylori infection is a common cause of this condition. Anti-HP treatment with metronidazole dispersible tablets and clarithromycin capsules can not only enhance the effect of killing pathogenic bacteria, but also effectively reduce the recurrence rate of the condition. The combination of omeprazole magnesium tablets and bismuth citrate potassium granules can reduce the stimulating effect on the patient by forming a protective layer on the surface mucosa of the stomach, inhibiting the acid secretion function of the glandular cells of the stomach wall, and accelerating the healing and repair of damaged tissues. Atropine sulfate tablets, as an anticholinergic agent, can effectively relieve the adverse symptoms such as gastric distension and pain, nausea and vomiting, acid reflux and heartburn caused by the disease.
