Best Medication for Chronic Epigastric Pain
The best medication for chronic epigastric pain is a proton pump inhibitor (PPI), such as omeprazole 20 mg once daily, as it is likely to be acid-related and can confirm the acid-related nature of the symptoms 1.
First-Line Therapy
- PPIs are recommended as first-line therapy for a duration of 8-12 weeks, with full dose PPI therapy, such as omeprazole 20 mg once daily, being the first choice of therapy in patients with ulcer-like dyspepsia 1.
- If symptoms persist, adding an H2 receptor antagonist like ranitidine 150-300 mg twice daily or switching to a different PPI may be considered 1.
- In cases where gastroesophageal reflux disease (GERD) is suspected, a trial of a PPI for 12-16 weeks is suggested, with dose escalation or addition of a prokinetic agent like metoclopramide 5-10 mg three times daily if necessary 1.
Alternative Options
- For patients with dysmotility-like dyspepsia, a prokinetic agent is an option, although cisapride can no longer be recommended due to cardiac toxicity 1.
- Neuromodulators such as tricyclic antidepressants (TCAs) and serotonin norepinephrine reuptake inhibitors (SNRIs) can reduce perception of pain at different levels of the brain-gut axis via multiple mechanisms, and may be considered for patients with refractory gastroparesis or functional dyspepsia 1.
- Selective serotonin reuptake inhibitors may improve coexisting anxiety and depression in patients with refractory gastroparesis, but are unlikely to directly improve visceral pain 1.
Important Considerations
- Opioid analgesics should not be used to manage chronic visceral abdominal pain, as they can further delay gastric emptying, increase the risk of narcotic bowel syndrome, and create the potential for addiction, tolerance, and overdose 1.
- Patients who do not respond to the first choice of symptomatic therapy may have been misclassified, and a switch of treatment should be considered 1.

From the Research
Treatment Options for Chronic Epigastric Pain
The treatment of chronic epigastric pain, often associated with gastroesophageal reflux disease (GERD), involves the use of proton pump inhibitors (PPIs) as the first-line therapy 2, 3, 4.
Proton Pump Inhibitors (PPIs)
PPIs are effective in reducing gastric acid production, thereby alleviating symptoms of GERD such as heartburn and regurgitation 4. The available PPIs, including omeprazole, lansoprazole, rabeprazole, and pantoprazole, have similar efficacy and safety profiles when used at recommended dosages 4.
Comparison of PPIs
- Omeprazole, lansoprazole, and esomeprazole have been compared in terms of their ability to provide symptom relief and heal esophageal erosions 3, 5.
- Lansoprazole and esomeprazole have been shown to provide similar degrees and onset of symptom relief, with both being more effective than omeprazole in some studies 5.
- Vonoprazan, a new potassium-competitive acid blocker, has been compared to PPIs in healing GERD, with some studies suggesting it may be more effective than certain PPIs, especially in patients with severe esophagitis 6.
Refractory GERD
In cases where patients do not respond to standard PPI therapy, the diagnosis of refractory GERD should be considered, and other causes of symptoms should be investigated 2. The management of PPI refractoriness involves correcting low adherence to PPI therapy, adjusting the PPI dosage, and emphasizing lifestyle modification changes 2.
Combination Therapy
The use of combination therapy with PPIs and histamine(2) receptor antagonists has been evaluated, but the clinical significance of this approach is not clear, and further investigation is needed to determine optimal therapy in patients refractory to standard doses of PPIs 3.
