Should a daily PPI be added to a patient's regimen while leaving antacids on as needed for breakthrough heartburn symptoms?

Management of Ongoing Heartburn Requiring Daily Antacid Use

For patients with ongoing heartburn requiring daily antacid use, a daily PPI should be added while keeping the antacid available as needed for breakthrough symptoms. 1, 2

Assessment of Frequent Antacid Use

Frequent antacid use for heartburn relief is often a sign of significant underlying gastroesophageal reflux disease (GERD) that requires more effective acid suppression therapy:

• Daily antacid use suggests inadequate symptom control with current management 3
• Patients with heartburn requiring frequent antacid use may have underlying esophagitis or other significant pathology even when symptoms seem moderate 3
• Antacids only transiently neutralize acid in the esophagus without preventing subsequent heartburn episodes 4

Evidence for Adding a PPI

The American Gastroenterological Association (AGA) recommends:

• Patients with troublesome heartburn should receive a 4-8 week trial of PPI therapy 1
• PPIs are significantly more effective than H2-receptor antagonists and antacids for both healing and symptom relief in GERD 2, 5
• Standard doses for initial PPI therapy include:
  • Omeprazole 20 mg once daily
  • Lansoprazole 30 mg once daily
  • Pantoprazole 40 mg once daily
  • Rabeprazole 20 mg once daily 2, 6

Managing Breakthrough Symptoms

Even with PPI therapy, some patients may experience breakthrough symptoms that require additional management:

• Keeping antacids available as PRN is recommended for breakthrough symptoms while on PPI therapy 1, 2
• The AGA clinical practice update supports the use of as-needed antacids for treatment of breakthrough symptoms in patients on PPI therapy 1
• Alginate-containing antacids may be particularly helpful for breakthrough symptoms in PPI-treated patients 7

Dosing Considerations

• Start with once-daily PPI dosing before considering twice-daily dosing 2
• Take PPI 30-60 minutes before a meal for optimal effectiveness 2
• If symptoms persist despite once-daily PPI, dosing can be increased to twice daily 1, 2
• When symptoms are controlled, PPI should be tapered to the lowest effective dose that maintains symptom control 2

Important Caveats

1. Rule out alarm symptoms: Dysphagia, weight loss, anemia, or GI bleeding require prompt endoscopic evaluation rather than empiric therapy 1, 2

2. Consider diagnostic testing: If symptoms persist despite 8 weeks of twice-daily PPI therapy, endoscopy and possibly pH monitoring should be considered 1

3. Avoid indefinite high-dose therapy without confirmed diagnosis: Patients on long-term PPI therapy should have the ongoing indication reviewed within 12 months 1, 2

4. Address lifestyle factors: Weight management, avoiding meals within 3 hours of bedtime, elevating the head of the bed, and avoiding trigger foods should be recommended alongside medication 2

By adding a daily PPI while keeping antacids available for breakthrough symptoms, you provide more effective acid suppression for ongoing symptoms while maintaining a rescue option for episodic breakthrough symptoms, which represents the optimal approach to managing persistent heartburn requiring daily antacid use.
