A sodium channel opener is a type of drug which facilitates ion transmission through sodium channels.
Examples include toxins, such as aconitine, veratridine, batrachotoxin, robustoxin, palytoxin and ciguatoxins and insecticides (DDT and pyrethroids), which activate voltage-gated sodium channels (VGSCs), and solnatide (AP301), which activates the epithelial sodium channel (ENaC).[1]
