    BackgroundEthnic differences exist in relation to culprit drugs for Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). We wanted to determine culprit drugs for SJS and TEN in Korean population.ObjectiveTo evaluate culprit drugs for SJS and TEN by applying an algorithm for assessment of drug causality for epidermal necrolysis (ALDEN) in a nationwide administrative database.MethodsWe used the claims database, which included claims data for the entire South Korean population. A retrospective cohort study was conducted by collecting subjects who were first diagnosed with SJS and TEN in 2011. All drugs prescribed to the subjects were reviewed and scored according to the ALDEN score. Drugs with an ALDEN score ≥2 were considered culprit drugs.ResultsA total of 187 subjects were included in the culprit drug analysis; 33 very probable, 101 probable, and 57 possible culprit drugs were identified for SJS and TEN according to the ALDEN score. The most frequently suspected culprit drug was allopurinol (19 cases), followed by carbamazepine (17 cases), lamotrigine (13 cases), amoxicillin (9 cases), and dorzolamide (9 cases). Most cases (78.8%, 52 of 66) associated with the use of allopurinol, carbamazepine, lamotrigine, dorzolamide, and methazolamide occurred between 13 and 44 days after initiating the drug.ConclusionWe applied the ALDEN score to the claims database to identify possible culprit drugs for SJS and TEN in South Korea. This approach could shed light on research and policymaking for drug adverse reactions.Copyright © 2019 American Academy of Allergy, Asthma & Immunology. Published by Elsevier Inc.
