Oxcarbazepine (OXC) modulated recovery from inactivation in hNav1.7 and SCN9A variants. A–D Shifts in the voltage-dependence of recovery from inactivation in the WT (A), N641Y (B), K655R (C), and W1150R (D) after treatment with 120 μmol/L OXC (curves are single exponential fits) and scatter plots of the time constant of recovery from inactivation. E Percentage recovery of ion channels treated with 120 μmol/L OXC. Data are the mean ± SEM. *P < 0.05, **P < 0.01, ***P < 0.001.
