Nociceptive neurons express several NaV1 channel subtypes that may contribute to the hyperexcitability characteristic of chronic pain states. The non-subtype selective, state-dependent NaV1 channel blockers lidocaine and carbamazepine are efficacious in the treatment of neuropathic pain; however, the target-driven development of novel sodium channel blocking analgesics has been generally unsuccessful. Recent human genetic data indicate an important role for the NaV1.7 channel subtype in pain signaling, and significant preclinical data identifies the NaV1.8 channel as a promising analgesic target, suggesting that the selective blockade of these subtypes may improve on the therapeutic index of sodium channel modulators. However, few subtype-selective small-molecule sodium channel blockers have been described.
