Mechanism of action Ranolazine inhibits persistent or late inward sodium current (INa) in heart muscle in a variety of voltage-gated sodium channels. Inhibiting that current leads to reductions in intracellular calcium levels.

The apparent terminal half-life of ranolazine is 7 hours. Steady state is generally achieved within 3 days of twice-daily dosing with RANEXA. At steady state over the dose range of 500 to 1000 mg twice daily, Cmax and AUC0-τ increase slightly more than proportionally to dose, 2.2-and 2.4-fold, respectively.
