Alomone Labs Carbamazepine inhibits NaV1.2 channels currents in Xenopus oocytes.A. Time course of NaV1.2 channel reversible inhibition by 100 µM and 1 mM Carbamazepine (#C-105). Currents were elicited by a voltage step to -20 mV (100 ms) every 10 seconds from a holding potential of -100 mV. B. Example traces of current response to voltage step application before and during 1 mM Carbamazepine application.

Voltage-gated sodium channels (VGSC, NaV) play a critical role in excitability of nociceptors (pain-sensing neurons). The peripheral-specific sodium channels NaV1.7, NaV1.8 and NaV1.9 are particularly important in the pathophysiology of different pain syndromes and hence, thought to be potential targets for pain therapeutics1-2.
Carbamazepine is a potent and state dependent inhibitor of neuronal NaV channels1. It is one of the most commonly prescribed antiepileptic drugs3 and has long been established as a treatment for neuropathic pain4. High doses of carbamazepine are effective in ameliorating symptoms of patients with paroxysmal extreme pain disorder (PEPD) because this disorder involves changes in NaV inactivation, a process that is modulated by NaV blockers. In a recent investigation patients with inherited erythromelalgia, characterized by a mutation in NaV1.7 (SCN9A) and a modified fast inactivation of Na+ current is present, reported an improvement of symptoms when treated with Carbamazepine5-6. In addition, clinical data also suggest that Carbamazepine can reduce aura and migraine attacks7.
Carbamazepine (#C-105) is a highly pure, synthetic, and biologically active compound.
