    Area of Science:

    • Gastroenterology
    • Pharmacology

    Background:

    • Antacids have been used for over a century for acid-related disorders.
    • Past recommendations for on-demand antacid use were based on misinterpretations of data.

    Purpose of the Study:

    • To evaluate the efficacy of antacids in ulcer healing.
    • To determine optimal antacid dosing and administration strategies.

    Main Methods:

    • Review of twelve endoscopic controlled studies on antacid efficacy.
    • Comparison of tablet and liquid antacid formulations.
    • Assessment of antacid combination therapy with anticholinergic drugs.

    Main Results:

    • Antacids demonstrated a 75% healing rate for duodenal ulcers within 4 weeks.
    • Efficacy in gastric ulcer healing remains controversial due to pathogenetic heterogeneity.
    • Optimal dosing involves neutralizing 400 mmol of acid, taken multiple times daily, especially after meals.

    Conclusions:

    • Antacids are effective for duodenal ulcer healing, highlighting the importance of controlling meal-stimulated acid secretion.
    • While effective, long-term antacid therapy faces compliance challenges due to frequent dosing requirements.
    • Newer tablet formulations show comparable efficacy to liquid forms.
