Conventional Medications for Stomach Ulcers: Proton Pump Inhibitors, H2 Receptor Antagonists, and Antibiotics
Proton pump inhibitors (PPIs) and histamine-2 receptor antagonists (H2RAs) are the main medications used to treat stomach ulcers. PPIs, such as omeprazole, are generally more effective than H2RAs in healing ulcers and relieving pain. Patients who do not respond to H2RAs often benefit from switching to a PPI. However, long-term use of PPIs can cause side effects like diarrhea, constipation, headaches, gastrointestinal infections, and an increased risk of bone fractures, especially in older adults. Calcium supplements are recommended for those on prolonged PPI therapy. Antibiotics are also used when Helicobacter pylori infection is present, as this bacterium is a major cause of peptic ulcers. Combination therapies, including PPIs and antibiotics, are standard for eradicating H. pylori, but challenges like drug resistance and poor drug delivery to the stomach lining can limit effectiveness Begg2023Gupta2023.
Medications That Can Cause or Worsen Stomach Ulcers: NSAIDs, Potassium Supplements, Bisphosphonates, and Doxycycline
Certain medications can increase the risk of developing stomach ulcers. Non-steroidal anti-inflammatory drugs (NSAIDs) are a common cause because they reduce the stomach’s protective mucus layer by inhibiting COX-1, making the stomach lining more vulnerable to acid. Potassium supplements, bisphosphonates (used for bone disorders), and doxycycline (an antibiotic) can also contribute to ulcer formation by increasing stomach acidity or reducing protective factors in the stomach lining Keller2024Alnajar2022.
Alternative and Herbal Treatments for Stomach Ulcers
Herbal remedies are being explored as alternatives or complements to conventional ulcer medications. Herbs such as liquorice, slippery elm, marshmallow root, aloe vera, chamomile, ginger, turmeric, meadowsweet, fenugreek, and cabbage have shown anti-inflammatory, antimicrobial, and mucoprotective effects in studies. These herbs may help heal ulcers and relieve symptoms, but safety and potential interactions with other medications should be considered. Integrating herbal remedies with standard treatments may improve outcomes for some patients Kiran2023Tiwari2023.
Natural compounds like rutin, a flavonoid found in many plants, have demonstrated anti-ulcer effects in experimental models by reducing inflammation and protecting the stomach lining. However, more research is needed to confirm their effectiveness and safety in humans . Other plant extracts, such as those from Albizia odoratissima and Hedera helix (English ivy), have also shown promise in animal studies for reducing ulcer severity and promoting healing through antioxidant and anti-inflammatory actions Sultana2024Hamood2025.
New and Adjunctive Therapies: Metformin and Novel Drug Formulations
Metformin, a medication commonly used for type II diabetes, has shown ulcer-healing effects similar to omeprazole in animal studies. Its benefits are linked to anti-inflammatory properties and increased nitric oxide levels, which help protect the stomach lining . Additionally, new drug formulations, such as extended-release and nanoformulations, are being developed to improve the delivery and effectiveness of ulcer medications, especially for treating H. pylori infections .
Conclusion
Stomach ulcers are most commonly treated with proton pump inhibitors, H2 receptor antagonists, and antibiotics, especially when H. pylori infection is involved. Some medications, like NSAIDs and certain supplements, can increase ulcer risk. Herbal remedies and natural compounds offer promising alternative or complementary options, but more research is needed to confirm their safety and effectiveness. New drug formulations and adjunctive therapies like metformin may further improve ulcer management in the future.
