Esophagitis caused by oral medication

J G Teplick, S K Teplick, S H Ominsky

    Radiology
    |January 1, 1980
    PubMed
    Summary

    Oral medications like quinidine and potassium chloride (KCl) can cause esophagitis, leading to inflammation or strictures. Pre-existing heart conditions may increase the risk of this rare medication side effect.

    Area of Science:

    • Gastroenterology
    • Pharmacology
    • Internal Medicine

    Background:

    • Esophagitis, or inflammation of the esophagus, can be an uncommon side effect of various oral medications.
    • Previous reports have identified several drugs implicated in medication-induced esophagitis, including potassium chloride (KCl) tablets, tetracycline, doxycycline, and ferrous sulfate.

    Observation:

    • This report details three new cases of esophagitis attributed to oral medications.
    • Two cases resulted from prolonged use of quinidine tablets, causing focal subacute inflammation and stricture.
    • One case occurred shortly after ingesting liquid potassium chloride (KCl).

    Findings:

    • Quinidine tablets can induce esophagitis with inflammation mimicking carcinoma or causing stricture.
    • Liquid potassium chloride (KCl) can also lead to acute esophagitis.
    • In cases involving KCl tablets, left atrial enlargement due to mitral stenosis was a common predisposing factor.

    Implications:

    • Clinicians should consider medication-induced esophagitis in patients presenting with esophageal symptoms.
    • Understanding predisposing factors, such as cardiac conditions, is crucial for preventing this adverse drug reaction.
    • Awareness of these associations can improve patient safety and diagnostic accuracy for esophageal pathologies.
