“…A limited number of drugs are associated with a high risk for SJS and TEN: several antiepileptic agents, especially carbamazepine, phenytoin, phenobarbital and lamotrigine, antibacterial sulfonamides, anti-inflammatory drugs of the oxicam family, allopurinol and the antiretroviral agent nevirapine. 1,2 Although the pathophysiology of SJS and TEN remains largely unknown, previous work suggests an immune mechanism involving a drug-dependent cytotoxic cell response against epidermal cells. Cytokines like TNFa and Fas ligand (FasL) may play a role in the final apoptosis of the keratinocytes, but the initial events triggering the adverse reaction remain to be identified.…”
