Mechanism of Action

The mechanism of action of ranolazine is unknown. It does not increase the rate-pressure product, a measure of myocardial work, at maximal exercise. In vitro studies suggest that ranolazine is a P-gp inhibitor. Ranolazine is believed to have its effects via altering the trans-cellular late sodium current. It is by altering the intracellular sodium level that ranolazine affects the sodium-dependent calcium channels during myocardial ischemia. Thus, ranolazine indirectly prevents the calcium overload that causes cardiac ischemia.


Absorption is highly variable. After oral administration of ranolazine as a solution, 73% of the dose is systemically available as ranolazine or metabolites. The bioavailability of oral ranolazine relative to that from a solution is 76%.
Hepatic, metabolized mainly by CYP3A and to a lesser extent by CYP2D6. The pharmacologic activity of the metabolites has not been well characterized.


In the event of overdose, the expected symptoms would be dizziness, nausea/vomiting, diplopia, paresthesia, and confusion. Syncope with prolonged loss of consciousness may develop.
