Esophagitis, the inflammation of the esophageal lining, can cause significant pain, difficulty swallowing, and other uncomfortable symptoms. The most effective treatment depends entirely on the cause, which can range from acid reflux and allergies to infections and medication side effects. For this reason, a doctor must first correctly diagnose the cause before prescribing a treatment plan. This article provides a comprehensive overview of the medication options available for different types of esophagitis.
Medications for Reflux Esophagitis
Reflux esophagitis is caused by stomach acid repeatedly flowing back into the esophagus, commonly due to gastroesophageal reflux disease (GERD). The primary goal of treatment is to reduce stomach acid and allow the esophageal tissue to heal.
Proton Pump Inhibitors (PPIs)
PPIs are the most effective class of medications for reducing stomach acid secretion. They work by blocking the H+/K+-ATPase enzyme system, the 'proton pump' in the stomach's parietal cells, which is the final step in acid production. This allows the damaged esophageal tissue to heal over time. PPIs can be used for short-term healing or long-term maintenance therapy in severe cases.
- Common PPIs include:
- Omeprazole (Prilosec)
- Lansoprazole (Prevacid)
- Esomeprazole (Nexium)
- Pantoprazole (Protonix)
- Vonoprazan (Voquezna), a newer potassium-competitive acid blocker (P-CAB)
H2-Receptor Antagonists (H2RAs)
H2RAs, such as famotidine (Pepcid), block histamine-2 receptors on stomach cells to decrease acid production. While generally less potent than PPIs, they can provide effective relief for milder cases and offer faster symptom relief than PPIs. Long-term use may lead to reduced efficacy (tachyphylaxis).
Antacids and Cytoprotective Agents
For immediate, temporary relief of heartburn, over-the-counter antacids like calcium carbonate (Tums) or magnesium hydroxide (Maalox) can neutralize existing stomach acid. However, they do not heal the esophagus. In certain cases, a cytoprotective agent like sucralfate (Carafate) may be used to create a protective coating over ulcerated tissue, though evidence for its efficacy in GERD-related esophagitis is limited.
Treating Eosinophilic Esophagitis (EoE)
EoE is an allergic or immune-mediated condition characterized by a buildup of eosinophils in the esophagus. Treatment focuses on reducing this inflammation.
Topical Steroids
Steroids delivered directly to the esophagus are the most common medication treatment for EoE. They act locally to reduce the inflammatory response.
- Budesonide: Often prepared as an oral viscous slurry that coats the esophagus. The oral suspension formulation (Eohilia) was approved in February 2024.
- Fluticasone: Delivered via an inhaler, with the medicine being sprayed into the mouth and swallowed instead of inhaled into the lungs.
Monoclonal Antibodies
For severe cases or those unresponsive to other therapies, the biologic drug dupilumab (Dupixent) may be prescribed. It blocks the signaling of interleukins IL-4 and IL-13, two proteins involved in the allergic inflammatory response.
Medications for Infectious Esophagitis
Infectious esophagitis primarily affects individuals with compromised immune systems and is treated with specific antimicrobial agents based on the causative organism.
- Fungal: Candida infections are common and are treated with antifungal medications, typically oral fluconazole.
- Viral: Herpes simplex virus (HSV) esophagitis is treated with antiviral drugs like acyclovir, famciclovir, or valacyclovir. Cytomegalovirus (CMV) esophagitis is treated with ganciclovir or foscarnet.
- Bacterial: Less common, but treated with broad-spectrum antibiotics if necessary.
Managing Pill-Induced Esophagitis
This type of esophagitis occurs when medications get lodged in the esophagus, causing irritation. Treatment involves addressing the immediate injury and preventing future occurrences.
- The primary treatment is to discontinue the offending medication or, if it's essential, to switch to a liquid form or an alternative drug.
- Pain management may include viscous lidocaine for temporary relief.
- Acid suppression and cytoprotection with PPIs or sucralfate can help protect the damaged lining while it heals.
- Important preventive measures include taking pills with a full glass of water and remaining upright for at least 30 minutes afterward.
Comparison of Esophagitis Medications
| Drug Class | Primary Use | Mechanism of Action | Typical Duration | Examples | Considerations |
|---|---|---|---|---|---|
| Proton Pump Inhibitors (PPIs) | Reflux Esophagitis, EoE (sometimes) | Blocks acid production in stomach | Short-term healing (4-8 weeks), or long-term maintenance | Omeprazole, Lansoprazole, Pantoprazole | Highly effective acid suppression, long-term use requires monitoring |
| H2-Receptor Antagonists (H2RAs) | Reflux Esophagitis (mild/infrequent) | Reduces stomach acid production by blocking H2 receptors | Short-term relief | Famotidine, Cimetidine | Faster relief than PPIs, but less potent and can lose efficacy over time |
| Topical Steroids | Eosinophilic Esophagitis (EoE) | Reduces local inflammation in the esophagus | Long-term maintenance | Budesonide (slurry), Fluticasone (swallowed aerosol) | Minimal systemic absorption, effective anti-inflammatory for EoE |
| Monoclonal Antibodies | Eosinophilic Esophagitis (severe) | Blocks inflammatory proteins (IL-4, IL-13) | Long-term maintenance | Dupilumab | Injectable biologic therapy for severe, refractory cases |
| Antifungal Agents | Infectious Esophagitis (Candida) | Inhibits fungal growth | Varies based on severity and immune status | Fluconazole, Nystatin | Must be specific to the infectious agent |
| Antiviral Agents | Infectious Esophagitis (viral) | Stops viral replication | Varies based on specific virus and immune status | Acyclovir (HSV), Ganciclovir (CMV) | Must be specific to the infectious agent |
| Cytoprotective Agents | Pill-Induced Esophagitis, Radiation Esophagitis | Coats and protects damaged esophageal lining | Temporary, until healing is complete | Sucralfate | Can protect mucosa, but not the primary treatment for underlying cause |
Lifestyle Adjustments and Maintenance Therapy
For many types of esophagitis, medications are used in combination with lifestyle changes. For reflux, this includes dietary adjustments, weight management, and elevating the head of the bed. In EoE, dietary elimination is a key component of management. Some conditions, particularly severe reflux or EoE, may require long-term or indefinite maintenance therapy with medication to prevent recurrence. Working closely with a healthcare provider is essential to find the lowest effective dose and duration of treatment to minimize side effects.
Conclusion
While a wide array of medications can treat esophagitis, the correct choice is dictated by the specific underlying cause. For acid reflux, PPIs are the most potent option, while EoE often requires targeted topical steroids or newer biologics. Infections are addressed with specific antifungal or antiviral agents, and pill-induced damage is managed by removing the offending medication and providing temporary protection. Always consult a healthcare professional for a proper diagnosis and treatment plan, as self-treatment may not address the root cause and could lead to complications.

Keypoint Summary
- Reflux Esophagitis Treatment: The primary medical treatment for reflux esophagitis involves potent acid suppressants like Proton Pump Inhibitors (PPIs) and, for milder cases, H2-receptor antagonists (H2RAs).
- EoE Requires Targeted Anti-Inflammatory Drugs: Eosinophilic esophagitis is often treated with topical corticosteroids, such as swallowed budesonide or fluticasone, to reduce local inflammation caused by allergic reactions.
- Infections Need Specific Antimicrobials: The type of infectious esophagitis determines the medication needed; for example, antifungals for Candida and antivirals for herpes or CMV are used to clear the infection.
- Pill Esophagitis Resolution is Cause-Specific: The first step in treating pill-induced esophagitis is to identify and stop taking the offending medication, with supportive medications like sucralfate or PPIs assisting in healing.
- Lifestyle Changes Complement Medication: Regardless of the type, medication for esophagitis is often most effective when combined with targeted lifestyle adjustments, such as dietary changes for reflux or EoE, to prevent recurrence and aid healing.
