Inhibits voltage-gated calcium and sodium channels (site 4). Inhibits activation by shifting the voltage-dependence of channel activation to more positive potentials. Potentlyinhibits all sodium chan nel subtypes tested (Nav1.2/SCN2A, Nav1.5/SCN5A, Nav1.7/SCN9A, and Nav1.8/SCN10A). Is approximately 15-fold more potent on Nav1.7/SCN9A than onNav1.5/SCN5A channels. Acts on Cav3.1/CACNA1G, and inter acts more weakly with the related T-Type channel Cav3.2/CACNA1H but potently inhibits the L-type calcium channelCav1.2/CACNA1C. Binds to phospholipids. ProTx-II, a selective inhibitor of Nav1.7 sodiu m channels, blocks action potential propagation in nociceptors.
