Esophageal mucosal irritation

Esophageal mucosal irritation is not a stand-alone diagnosis but a symptom: burning, throat clearing and retrosternal soreness without erosions or ulcers on endoscopy. The most common cause is GERD without esophagitis (NERD); less common ones are drug-induced esophagitis (doxycycline, bisphosphonates, NSAIDs taken without water), post-surgical reaction or irritation from hot and spicy food. Standard workup per NICE NG12 and the Spanish AEG guideline includes a drug history, alarm-symptom assessment and an empirical PPI course. Endoscopy is indicated for PPI-resistant symptoms or alarm symptoms (dysphagia, weight loss, hematemesis). Demulcent supplements (slippery elm, marshmallow, flaxseed) soften symptoms mildly but do not replace PPIs in confirmed GERD and do not treat the underlying cause.

Drugs used for this condition

DSlippery elm (inner bark)Add-on therapy · Over-the-counter botanical supplement, the inner bark of Ulmus rubra (slippery elm, a North American tree); a mucilage demulcent with traditional use for irritation of the gastrointestinal and throat mucosaSlippery elm is an over-the-counter botanical supplement with traditional use as a mucilage demulcent for irritation of the esophagus and throat. Clinical RCTs in esophageal irritation with a burning-relief endpoint do not exist; the proposed mechanism is mechanical coating of the mucosa with a viscous film. NCCIH 2020 describes slippery elm as a traditional use product without quality evidence. EMA HMPC has no separate monograph on Ulmus rubra. AEMPS and AESAN classify the product as a complemento alimenticio without therapeutic indication. Standard care for esophageal irritation per NICE CG184 and ACG 2022 includes a drug history (especially doxycycline, bisphosphonates or NSAIDs without water), an empirical PPI course for 4–8 weeks and endoscopy for alarm symptoms or refractoriness. Slippery elm may be a mild symptomatic adjunct for light throat clearing and burning (for example after irritation from hot or spicy food), but for suspected GERD discuss with a gastroenterologist or family doctor – PPIs give systemic protection, demulcents give short local relief.

How to read tiers A–F

Evidence tiers belong to the drug-indication pair, not to the drug as a whole: the same substance can be A for one condition and F for another.

AStrong evidence – first or second line in international guidelines
BRecommended in selected cases
CStudy data contradict each other
DBenefit not proven, no documented harm
FDocumented harm, or risk without benefit
