BupivacaineisanaminoamideanestheticthatdecreasescurrentamplitudeandinhibitswholecellK+currentsinCa2+-activatedK+channelsandN-typevoltage-gated(Kv1/ShakerandKv3/Shaw[KCNAandKCNC])K+channels.Bupivacainealsoinhibitsvoltage-gatedNa+channelsandtandemporedomain(TASK-2/KCNK-5)K+channels.Bupivacainemaybeneurotoxicathighdoses,activatingp38MAPK,increasinglevelsofROSandWDR53,andinducingapoptosisinneuroblastomacells.Inothercellularmodels,bupivacaineinducesdepolarizationofthemitochondrialmembranepotential,resultinginapoptosis.
