are antacids a good substitute for treating heartburn
The short version: antacids are a reasonable quick fix for occasional heartburn, but they are not a substitute for treating the underlying problem, and the evidence here is thin on long-term outcomes.
The retrieved studies mostly compare acid-suppressing drugs, not antacids. One older trial found an antacid product relieved heartburn in about 80 in 100 pregnant women, versus 56 in 100 on placebo [1]. Another showed an antacid chewing gum reduced symptoms and improved esophageal pH [3]. That is real short-term symptom relief.
But antacids only neutralize acid already in the stomach. They do not stop reflux events, heal damaged tissue, or address why the valve is leaking. For that, the evidence favors acid suppressors: PPIs heal erosive esophagitis faster than H2 blockers [2], and a Cochrane review found PPIs beat H2 blockers for heartburn remission [5]. One trial showed people on a PPI needed about half the antacid rescue doses of those on placebo [4].
The real question is what "substitute" means. For occasional heartburn after a meal, antacids work. For frequent symptoms, erosive damage, or nighttime reflux, they are a band-aid, not a treatment. The evidence here does not include any long-term study of antacids versus PPIs on healing or complications, so that comparison is simply unmeasured.
| Approach | Symptom relief | Heals tissue | Evidence quality |
|---|---|---|---|
| Antacids | Yes, short-term [1][3] | No evidence | Thin, old trials |
| H2 blockers | Yes | Partial [2] | Moderate |
| PPIs | Yes, faster [2][5] | Yes [2][5] | Stronger |
My call: antacids are fine for occasional heartburn, but not a substitute for treating frequent reflux or erosive disease. Confidence: moderate for short-term symptom relief, not clear for whether antacids match PPIs on healing, because that comparison was never studied in this evidence.

A Prokinetic Approach to Treatment of Gastroesophageal Reflux Disease
In this GERD treatment review, omeprazole produced faster mucosal healing than H2 antagonists, cisapride reduced symptoms in erosive esophagitis trials, and H2RA adverse reactions were about 4%.

Six‐month trial of on‐demand rabeprazole 10 mg maintains symptom relief in patients with non‐erosive reflux disease
In a multicentre, randomized, double-blind withdrawal trial, on-demand rabeprazole 10 mg maintained symptom relief and reduced discontinuation due to inadequate heartburn control over 6 months in adults with non-erosive GERD (NERD) compared with placebo.

Short-term treatment with proton pump inhibitors, H2-receptor antagonists and prokinetics for gastro-oesophageal reflux disease-like symptoms and endoscopy negative reflux disease
This study evaluates the efficacy of short-term treatment with proton pump inhibitors, H2-receptor antagonists, and prokinetics in adults with gastro-oesophageal reflux disease (GORD) and endoscopy negative reflux disease (ENRD), finding that PPIs are more effective than H2RAs a…
