Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Bicarbonate (mixed), often administered as sodium bicarbonate or in antacid mixtures, has been used to support or treat duodenal ulcers primarily due to its ability to neutralize gastric acid. The scientific rationale is based on the fact that duodenal ulcers are associated with excess gastric acid, which damages the mucosa of the duodenum. Bicarbonate acts as a chemical buffer, raising the pH of gastric contents, thereby reducing acidity and providing symptomatic relief.

Historically, before the advent of more effective medications such as H2-receptor antagonists (e.g., cimetidine) and proton pump inhibitors (e.g., omeprazole), antacids containing bicarbonate were a mainstay of ulcer therapy. However, scientific evidence supporting bicarbonate as a long-term or curative treatment for duodenal ulcers is limited. While bicarbonate offers rapid symptomatic relief by neutralizing acid, it does not address the underlying causes of ulceration, such as Helicobacter pylori infection or chronic NSAID use.

Clinical guidelines now recommend against routine use of bicarbonate-based antacids for duodenal ulcer healing due to their short duration of action, potential side effects (such as metabolic alkalosis), and the availability of superior therapies. In summary, while there is scientific rationale for its symptomatic use, the evidence for its efficacy in healing or significantly altering the natural history of duodenal ulcers is weak. Thus, its use is primarily as an adjunct for short-term symptom relief rather than as a primary therapy.
