“…In literature, the major causative agents of esophageal injuries have been identified to be tetracycline, doxycycline, and clindamycin; however, frequently used drugs such as other anti-inflammatory agents, alendronate, iron sulfate, dabigatran, and vitamin C were reported to cause similar damage (6,8,9,12,15). Telithromycin was reported to cause chemotherapy-induced esophagitis in rare cases (16,17). In this study, the causative agent was detected to be tetracycline in two cases, doxycycline in two cases, and tramadol HCl in one case.…”
