Which of the following medications is commonly prescribed for gastritis treatment?

Sucralfate is commonly prescribed for the treatment of gastritis due to its unique mechanism of action as a mucosal protective agent. In gastritis, the gastric mucosa becomes inflamed, leading to discomfort and potential complications. Sucralfate works by forming a protective barrier over ulcerated or inflamed gastric tissue, allowing for healing and reducing the risk of further irritation from gastric acids. This barrier also enhances the mucosal defense against bile acids and pepsin, contributing to symptom relief and healing.

In contrast, other medications listed are not typically indicated for gastritis management. Metformin is primarily used for managing type 2 diabetes and does not address gastric mucosal inflammation. Amoxicillin, while an antibiotic, is generally used in the context of eradicating H. pylori infection, which may contribute to chronic gastritis; however, it is not a direct treatment for gastritis itself. Simvastatin is a statin used to manage cholesterol levels, and it does not have relevance in treating gastritis. Thus, sucralfate stands out as the appropriate choice for addressing the specific needs of patients with gastritis.
