What medication is often used in the treatment of gastric ulcers?

Amoxicillin is often used in the treatment of gastric ulcers, particularly when the ulcers are associated with Helicobacter pylori infection. This bacterium plays a significant role in the development of peptic ulcers, and eradicating it can lead to healing of the ulcer and prevent recurrence. Amoxicillin, an antibiotic, works by inhibiting the growth of the bacteria, helping to treat the underlying cause of the ulcer.

Other options, such as Metformin, Atorvastatin, and Levothyroxine, serve different medical purposes unrelated to the treatment of gastric ulcers. Metformin is primarily used to manage type 2 diabetes, Atorvastatin is used to lower cholesterol levels, and Levothyroxine is a thyroid hormone replacement therapy for hypothyroidism. None of these medications address the bacterial infection commonly associated with gastric ulcers, which highlights the specificity of Amoxicillin's role in this context.
