Management of acute carbamazepine poisoning:A narrative review

Standard management protocols are lacking and specific antidotes are unavailable for acute carbamazepine(CBZ)poisoning.The objective of this review is to provide currently available information on acute CBZ poisoning,including its management,by describing and summarizing various therapeutic methods for its treatment according to previously published studies.Several treatment methods for CBZ poisoning will be briefly introduced,their advantages and disadvantages will be analyzed and compared,and suggestions for the clinical treatment of CBZ poisoning will be provided.A literature search was performed in various English and Chinese databases.In addition,the reference lists of identified articles were screened for additional relevant studies,including non-indexed reports.Nonpeer-reviewed sources were also included.In the present review,154 articles met the inclusion criteria including case reports,case series,descriptive cohorts,pharmacokinetic studies,and in vitro studies.Data on 67 patients,including 4 fatalities,were reviewed.Based on the summary of cases reported in the included articles,the cure rate of CBZ poisoning after symptomatic treatment was 82%and the efficiency of hemoperfusion was 58.2%.Based on the literature review,CBZ is moderately dialyzable and the recommendation for CBZ poisoning is supportive management and gastric lavage.In severe cases,extracorporeal treatment is recommended,with hemodialysis as the first choice.
