ABSTRACT
Aim The effects of midazolam on the whole-cell sodium currents in rat sympathetic neurons were studied to explore the mechanisms where by midazolam mediates hypotension. Methods Whole-cell patch-clamp recordings were performed on enzymatically isolated rat superior cervical sympathetic neurons. Results Midazolam dose-dependently blocked the whole-cell sodium currents evoked by a voltage step to 0 mV from a holding potential of -80 mV with a mean drug concentration required to produce 50% current inhibition (IC50) values of 18.35 ?mol?L-1; Clinically relevant concentration of midazolam(0.3 ?mol?L-1) reduced sodium peak currents by 19.98%(P
