Sample Use Guides

Adults: Oral: 12.5 mg twice daily, may increase at intervals of 1-2 weeks; maximum dose: 100-150 mg/day in divided doses
Route of Administration: Oral
In murine WT ventricular cells, pinacidil (1-100uM) concentration-dependently induced an outward current and action potential shortening, effects that were blocked by glibenclamide, a K(ATP) channel blocker.
