Tonabersat is an anti-migraine agent.{40037,40034} It binds to connexin43 hemichannels and inhibits ATP release in vitro during injury and reperfusion in a dose-dependent manner.{40033} This inhibition blocks trigeminal ganglion neuronal-satellite glial cell signaling and cortical spreading depression, a trigger of migraine pain.{40033,40034,40035} In vivo, tonabersat (10 mg/kg) increases the seizure threshold in maximal electroshock seizure threshold (MEST) mice and rats (143 and 1192%, respectively) and completely blocks neurogenic plasma extravasation, a marker of migraine pain, in a rat trigeminal nerve migraine model.{40036}
