Many specialists and general physicians remain unaware of the potential for and pathogenesis of drug-induced esophageal ulcerations. To promote a greater awareness of the importance of this problem, we have reviewed the literature, particularly in regard to the mechanisms of action and the clinical and therapeutic implications of these chemical injuries to the esophagus. There can be no doubt that the frequency of occurrence of drug-induced esophageal ulceration far exceeds that reflected in the reported cases appearing in the medical literature. Nor can we deny that much of the responsibility for this situation lies in the failure of the prescribing physician to educate his patients (
and himself!)
in the art of taking potentially harmful pills and capsules, particularly tetracycline, doxycycline, potassium chloride, and quinidine preparations. Although most such drug injuries are self-limited events, there have been a number of fatalities reported and at the very least they involve acute discomfort.
