Effect of charcoal hemoperfusion on clearance of cibenzoline succinate (cifenline) poisoning

Background: Management of cibenzoline succinate (cifenline) poisoning by sy mptomatic treatment is recommended because it has been reported cibenzoline succinate is not effectively removed by hemodialysis.(1) The use of charco al hemoperfusion for patients with cibenzoline succinate poisoning has not been reported previously. Case Report: An 80-year-old woman with permanent right ventricular pacing was admitted to our hospital with general fatigue and clouding of consciousness. She had been receiving cibenzoline succinate for 1 month. The patient was clearly in shock on admission. Electrocardiog ram showed a prolonged QRS and QTc interval and pacing failure. Hemodynamic failure, electrocardiographic abnormalities including pacing failure, and liver and renal dysfunction were compatible with cibenzoline succinate pois oning, Symptomatic treatment was provided. On day 4, charcoal hemoperfusion was initiated because of the development of hypoglycemia accompanied by li ver and renal dysfunction. After charcoal hemoperfusion, the hypoglycemia, liver and renal dysfunction, prolonged QRS and QTc interval, and pacing thr eshold resolved. She was discharged on digoxin, We present a case of cibenz oline succinate poisoning treated with charcoal hemoperfusion which resulte d in a rapid reduction of cibenzoline plasma concentrations with a signific ant clinical improvement.
