How Stomach Ulcer Medications Work

Stomach ulcers are open sores that develop on the inside lining of the stomach. They can cause abdominal pain, nausea, vomiting, and bleeding. The primary goal of medication treatment is to reduce acid production in the stomach and promote healing.

Treatment Options

• Gold Standard: Proton Pump Inhibitors (PPIs)
• PPIs work by irreversibly inhibiting the H+/K+ ATPase enzyme system at the secretory surface of gastric parietal cells, reducing acid production.
• Examples include omeprazole and lansoprazole.
• Alternatives:
• Histamine-2 receptor antagonists (H2RAs): Reduce acid production by blocking histamine receptors on parietal cells. Examples include ranitidine and famotidine.
• Sucralfate: Forms an ulcer-adherent complex that protects the ulcer site from acid and enzymes, promoting healing.
• Antibiotics for H. pylori eradication: Used in combination with PPIs or other treatments to eliminate the bacterial infection causing the ulcer.

Key Considerations

Medications may be prescribed based on diagnostic tests, such as endoscopy, upper GI series, and blood tests for Helicobacter pylori. Treatment duration and choice of medication depend on individual patient factors, including the presence of H. pylori infection and use of nonsteroidal anti-inflammatory drugs (NSAIDs).
