Here is a comprehensive, evidence-based answer on the treatment of indigestion (dyspepsia):

Treatment of Indigestion (Dyspepsia)

"Indigestion" is the lay term for dyspepsia - a group of symptoms (upper abdominal pain or discomfort, bloating, early satiety, nausea) arising from the upper GI tract. Treatment is guided by whether an underlying cause is found.

Step 1 - Rule Out Organic Causes & Alarm Features

Before treating, consider whether the patient needs investigation:
  • Alarm features (weight loss, anemia, dysphagia, vomiting blood, age >45-55 with new-onset symptoms) - prompt upper GI endoscopy is required.
  • No alarm features in a young patient - empirical treatment is acceptable.
  • Always stop NSAIDs if possible, as they are a common culprit. If NSAIDs cannot be stopped, add a PPI.

Step 2 - Test & Treat for H. pylori

The first-line strategy for uninvestigated dyspepsia (no alarm features, age <45) is the "test and treat" approach:
  1. Test non-invasively for H. pylori (urea breath test or stool antigen test)
  2. If positive, eradicate with PPI + two antibiotics for 10-14 days (standard triple or bismuth quadruple therapy per ACG 2024 guidelines, PMID: 39626064)
  3. H. pylori eradication achieves sustained remission in a subset ("Hp-associated dyspepsia"), and also reduces peptic ulcer disease and gastric cancer risk (NNT ~12.5 for dyspepsia symptom benefit)

Step 3 - Pharmacological Treatment of Functional Dyspepsia (FD)

About 70% of dyspeptic patients have functional dyspepsia (FD) - no structural cause found on endoscopy. Treatment is symptom-subtype driven per Rome IV:
Functional Dyspepsia Management Algorithm

A. Epigastric Pain Syndrome (EPS) - burning/pain, not meal-related

Drug ClassDetails
PPIs (first line)Omeprazole, lansoprazole, pantoprazole; NNT ~10 vs placebo; standard dose, 4-8 weeks
H2-receptor antagonistsFamotidine, ranitidine; NNT ~7; useful alternative, though most trials predated Rome criteria
Tricyclic antidepressantsAmitriptyline (low dose) for refractory EPS - works via central pain modulation

B. Postprandial Distress Syndrome (PDS) - meal-induced fullness, early satiety

Drug ClassDetails
Prokinetics (first line)Metoclopramide, domperidone, itopride, acotiamide; improve gastric emptying and accommodation
PPIsAdd or switch if prokinetic alone insufficient
5-HT1A agonistsBuspirone - reduces fundic accommodation abnormalities; for prominent early satiation
Mirtazapine 15 mgFor early satiation with weight loss (BSG 2025 guideline; evidence still limited)

Step 4 - General & Lifestyle Measures

These apply to all patients with dyspepsia:
  • Dietary changes: Eat smaller, more frequent meals; avoid fatty/spicy foods, alcohol, caffeine, carbonated drinks
  • Weight management: Obesity worsens symptoms
  • Smoking cessation: Smoking impairs gastric motility
  • Stress reduction: Dyspepsia is closely linked to psychological stress; relaxation techniques help
  • Reassurance: Explaining the benign nature of functional dyspepsia is itself therapeutic

Step 5 - Refractory Functional Dyspepsia

If symptoms persist despite the above:
  • Low-dose tricyclic antidepressants (amitriptyline, nortriptyline) - well-supported by evidence
  • SNRIs (duloxetine) - emerging evidence
  • Cognitive behavioral therapy (CBT) or gut-directed hypnotherapy - effective for the gut-brain axis component; recommended for refractory cases
  • Gastric emptying study - if delayed, consider a stronger prokinetic (e.g., prucalopride)
  • Psychological/psychiatric referral - for long-standing refractory or debilitating symptoms

Quick Reference by Cause

CauseTreatment
H. pylori infectionPPI + antibiotics (triple/quadruple therapy)
NSAID-inducedStop NSAID; PPI for protection
GERD overlapPPI
Peptic ulcer diseasePPI + H. pylori eradication if positive
Functional (EPS)PPI or H2RA
Functional (PDS)Prokinetic; add PPI if needed
Refractory FDTCA, CBT, hypnotherapy

Key takeaway: The best treatment depends on the underlying cause. For most patients without alarm features, start with H. pylori test-and-treat plus acid suppression (PPI), lifestyle modification, and reassurance. Refractory cases benefit from low-dose antidepressants and gut-directed psychological therapy.

Just till me drugs

Here are the drugs used for indigestion/dyspepsia:

Antacids (mild/occasional symptoms)

  • Aluminium hydroxide
  • Magnesium hydroxide
  • Calcium carbonate (Tums)
  • Sodium bicarbonate

Proton Pump Inhibitors - PPIs (acid suppression, first line for EPS)

  • Omeprazole
  • Pantoprazole
  • Lansoprazole
  • Esomeprazole
  • Rabeprazole

H2-Receptor Antagonists (acid suppression, alternative to PPIs)

  • Famotidine
  • Ranitidine
  • Cimetidine

Prokinetics (first line for PDS - bloating, fullness, early satiety)

  • Metoclopramide
  • Domperidone
  • Itopride
  • Acotiamide
  • Prucalopride (refractory, delayed gastric emptying)

H. pylori Eradication (if H. pylori positive)

  • PPI + Amoxicillin + Clarithromycin (standard triple therapy)
  • PPI + Bismuth + Metronidazole + Tetracycline (quadruple therapy)

Neuromodulators (refractory/functional dyspepsia)

  • Amitriptyline (low dose TCA)
  • Nortriptyline (low dose TCA)
  • Mirtazapine 15 mg (especially with weight loss + early satiation)
  • Duloxetine (SNRI)
  • Buspirone (5-HT1A agonist - impaired fundic accommodation)

Cytoprotective

  • Sucralfate (limited evidence)

Combinations

Here are the standard drug combinations used in indigestion/dyspepsia:

H. pylori Eradication Regimens

Standard Triple Therapy (14 days)
  • PPI + Amoxicillin 1g + Clarithromycin 500mg (all BD)
Bismuth Quadruple Therapy (14 days)
  • PPI + Bismuth subcitrate + Metronidazole + Tetracycline (all QID)
Concomitant Therapy
  • PPI + Amoxicillin + Clarithromycin + Metronidazole (all BD)
Hybrid Therapy
  • PPI + Amoxicillin (7 days) → then PPI + Amoxicillin + Clarithromycin + Metronidazole (7 days)

Functional Dyspepsia Combinations

EPS not responding to PPI alone
  • PPI + Prokinetic (e.g., Pantoprazole + Domperidone)
PDS not responding to prokinetic alone
  • Prokinetic + PPI (e.g., Itopride + Omeprazole)
Refractory FD
  • PPI + Low-dose TCA (e.g., Omeprazole + Amitriptyline)
Overlap with GERD
  • PPI (double dose) + Prokinetic
Overlap with IBS
  • PPI + Antispasmodic (e.g., Mebeverine or Dicyclomine)

Common Fixed-Dose Commercial Combinations

  • Pantoprazole + Domperidone (very widely used)
  • Omeprazole + Domperidone
  • Rabeprazole + Domperidone
  • Lansoprazole + Domperidone
  • Esomeprazole + Itopride

Note: Fixed-dose PPI + prokinetic combinations are popular in clinical practice (especially in South Asia) for mixed EPS/PDS presentations, though guidelines generally recommend tailoring by symptom subtype.
