Ranolazine has been shown to prolong the QT interval corrected for rate (QTc) in a dose-related manner. Although the clinical importance of QTc interval prolongation associated with ranolazine is not known, other drugs with this potential have been associated with torsades de pointes-type arrhythmias and sudden death. The mean effect on QTc interval with repeated dosing of ranolazine 1 g twice daily, at time of maximum plasma concentration (Tmax), is about 6 msec; however, in 5% of the population the prolongation of QTc interval is 15 msec. Age, weight, gender, race, heart rate, NYHA class I to IV CHF, and diabetes have no substantial effect on the relationship between ranolazine plasma concentrations and increases in QTc interval. The relationship between ranolazine concentrations and QTc remains linear over a concentration range up to fourfold greater than the concentrations produced by a ranolazine dosage of 1 g twice daily, and is not affected by changes in heart rate. The manufacturer states that ranolazine dosages exceeding 1 g twice daily should not be used.
American Society of Health-System Pharmacists 2011; Drug Information 2011. Bethesda, MD. 2011, p. 1733
The effects of ranolazine in patients with preexisting QT interval prolongation or receiving concomitant therapy with drugs that are known to prolong the QT interval have not been established. Because of possible additive effects on the QT interval, the manufacturer states that use of ranolazine should be avoided in patients with known QT interval prolongation (including congenital long QT syndrome and uncorrected hypokalemia), known history of ventricular tachycardia, and in patients receiving drugs that prolong the QTc interval (eg, class Ia (eg, quinidine) or III (eg, dofetilide, sotalol) antiarrhythmic agents, antipsychotic agents eg, thioridazine, ziprasidone).
American Society of Health-System Pharmacists 2011; Drug Information 2011. Bethesda, MD. 2011, p. 1733
Because the QTc-prolonging effect is increased approximately threefold in patients with hepatic dysfunction, ranolazine is contraindicated in patients with mild, moderate, or severe hepatic impairment.

Ranolazine is indicated for the treatment of chronic angina. It can be used alone or in conjunction with nitrates, beta-blockers, angiotensin receptor blockers, anti-platelet drugs, calcium channel blockers, lipid-lowering drugs, and ACE inhibitors. Ranolazine has also been used off-label for the treatment of certain arrhythmias, including ventricular tachycardia, however, this use is not strongly supported by scientific evidence. Ranolazine has also been studied for the treatment of acute coronary syndrome, microvascular coronary dysfunction, arrhythmia, and glycemic control, which are not yet approved indications.
FDA Label
Ranexa is indicated as add-on therapy for the symptomatic treatment of patients with stable angina pectoris who are inadequately controlled or intolerant to first-line anti-anginal therapies (such as beta-blockers and / or calcium antagonists).
Ranolazine exerts both antianginal and ischemic effects independent from lowering heart rate or blood pressure. It blocks IKr, the rapid portion of the delayed rectifier potassium current, and prolongs the QTc interval in a dose-dependent fashion. The Ikr is important for cardiac repolarization. Ranolazine exerts its therapeutic effects without negative chronotropic, dromotropic, or inotropic actions neither at rest, nor during exercise.
Sodium Channel Blockers
A class of drugs that act by inhibition of sodium influx through cell membranes. Blockade of sodium channels slows the rate and amplitude of initial rapid depolarization, reduces cell excitability, and reduces conduction velocity. (See all compounds classified as Sodium Channel Blockers.)
Cardiovascular Agents
Agents that affect the rate or intensity of cardiac contraction, blood vessel diameter, or blood volume. (See all compounds classified as Cardiovascular Agents.)

Absorption
The time to reach peak serum concentration is quite variable but has been observed to be in the range of 2-6 hours, with steady-state within 3 days. The FDA indicates a Tmax of 3-5 hours. The average steady-state Cmax is about 2600 ng/mL. Absorption of ranolazine is not significantly affected by food consumption. The bioavailability of ranolazine taken in the tablet form compared to that from a solution of ranolazine is about 76%.
Route of Elimination
From the administered dose, about 3/4 of the dose is excreted renally, while 1/4 of the dose is excreted in the feces. An estimated 5% of an ingested dose is excreted as unchanged drug.
Volume of Distribution
The mean apparent volume of distribution of ranolazine is reported to be 53.2 L and the average steady-state volume of distribution is estimated to range from 85 to 180 L.
Clearance
The reported clearance rate of orally administered ranolazine is of 45 L/h when administered at a dose of 500 mg twice daily. The clearance rate of ranolazine is dose-dependent and renal impairment can increase ranolazine serum concentration by 40-50%.
Ranolazine is extensively metabolized in the gut and liver and its absorption is highly variable. For example, at a dose of 1000 mg twice daily, the mean steady-state Cmax was 2600 ng/mL with 95% confidence limits of 400 and 6100 ng/mL. The pharmacokinetics of the (+) R- and (-) S-enantiomers of ranolazine are similar in healthy volunteers. ... Steady state is generally achieved within 3 days of twice-daily dosing with ranolazine. At steady state over the dose range of 500 to 1000 mg twice daily, Cmax and AUC0-t increase slightly more than proportionally to dose, 2.2- and 2.4-fold, respectively. With twice-daily dosing, the trough:peak ratio of the ranolazine plasma concentration is 0.3 to 0.6. The pharmacokinetics of ranolazine is unaffected by age, gender, or food.

After oral administration of ranolazine, peak plasma concentrations of ranolazine are reached between 2 and 5 hours. After oral administration of (14)C-ranolazine as a solution, 73% of the dose is systemically available as ranolazine or metabolites. The bioavailability of ranolazine from ranolazine tablets relative to that from a solution of ranolazine is 76%. Because ranolazine is a substrate of P-gp, inhibitors of P-gp may increase the absorption of ranolazine.

Food (high-fat breakfast) has no important effect on the Cmax and AUC of ranolazine. Therefore, ranolazine may be taken without regard to meals. Over the concentration range of 0.25 to 10 ug/mL, ranolazine is approximately 62% bound to human plasma proteins.

Ranolazine is rapidly heavily metabolized in the liver an gastrointestinal tract through the activity of the CYP3A4 enzyme with minor contributions from CYP2D6. More than 40 ranolazine metabolites have been found in plasma and more than 100 metabolites have been identified in the urine. Ranolazine and some of its metabolites are known to weakly inhibit CYP3A4. However, the activity of the metabolites of ranolazine has not been fully elucidated.
Ranolazine is extensively metabolized in the intestine and liver by the cytochrome P-450 (CYP) isoenzyme system, mainly by CYP3A and, to a lesser extent, CYP2D6. In vitro studies indicate that ranolazine also is a p-glycoprotein substrate. At least 4 metabolites of ranolazine have been identified. The pharmacologic activity of these metabolites has not been fully established.

Myocardial ischemia exerts effects on adenosine triphosphate flux, leading to a decrease in the energy available for contraction and relaxation of the heart muscle. Electrolyte balance of sodium and potassium is necessary for maintaining normal cardiac contraction and relaxation. Disruption of adequate sodium and potassium electrolyte balance leads to excessively high concentrations of sodium and calcium, which likely interferes with oxygen supply to the heart muscle. This imbalance eventually leads to angina symptoms of chest pain or pressure, nausea, and dizziness, among others. The mechanism of action for ranolazine is not fully understood. At therapeutic concentrations, it can inhibit the cardiac late sodium 205 current (INa), which may affect the electrolyte balance in the myocardium, relieving angina symptoms. The clinical significance this inhibition in the treatment of angina symptoms is not yet confirmed. Ranolazine inhibits sodium and potassium ion channel currents. It has been shown to exert weak activity on L-type calcium channels making it a weak direct vasodilator and exerts minimal direct effects on atrioventricular nodal conduction. Some additional mechanisms have been elucidated. Ranolazine exerts antagonistic activity towards the alpha 1 and beta 1 adrenergic receptors and inhibition of fatty acid oxidation.
Ranolazine, a piperazine derivative, is an antianginal agent. Although the exact mechanism of antianginal activity of ranolazine has not been fully elucidated, results of early studies suggested that ranolazine shifted adenosine triphosphate (ATP) production away from fatty acid oxidation (ie, partial inhibition of fatty acid oxidation) in favor of more oxygen-efficient glucose oxidation, especially when free fatty acid concentrations were elevated (eg, during ischemia), leading to reduced oxygen demand and symptoms of ischemia without affecting cardiac work. However, these pharmacologic effects generally were observed at concentrations exceeding therapeutic plasma concentrations in clinical studies.
American Society of Health-System Pharmacists 2011; Drug Information 2011. Bethesda, MD. 2011, p. 1734
Recent data suggest that ranolazine may exert its antianginal and anti-ischemic effects through concentration-, voltage-, and frequency-dependent inhibition of the late (ie, sustained, persistent) sodium current and other cardiac ion channels and transporters. The late sodium current is created by inactivation of the sodium channel protein. However, angina (ie, ischemia, hypoxia) impairs sodium channel inactivation and increases the amount of sodium in cardiac cells, which facilitates calcium overload via the sodium-calcium exchange pump. Increased intracellular calcium may result in myocyte hyperexcitability and electrical instability, impaired diastolic relaxation, reduced coronary artery perfusion, impaired myocardial oxygen supply, increased oxygen demand, and ventricular dysfunction. Thus, ranolazine may decrease the magnitude of the late sodium current resulting in a net reduction in intracellular sodium concentrations, reversal of calcium overload, restoration of ventricular pump function, and prevention of ischemia-induced arrhythmias. Unlike other antianginal agents, the antianginal effects of ranolazine are not dependent upon reductions in heart rate or blood pressure.

The QT prolongation effect of ranolazine on the surface electrocardiogram is the result of inhibition of IKr, which prolongs the ventricular action potential.
US Natl Inst Health; DailyMed. Current Medication Information for RANEXA (ranolazine) tablet, film coated, extended release (March 2010). Available from, as of July 11, 2011: https://dailymed.nlm.nih.gov/dailymed/lookup.cfm?setid=739d7705-907b-4408-8490-2052514a1a50
/The authors/ investigated changes in Na(+) currents (I(Na)) in permanent (or chronic) atrial fibrillation (AF) and the effects of I(Na) inhibition using ranolazine (Ran) on arrhythmias and contractility in human atrial myocardium. Electrical remodeling during AF is typically associated with alterations in Ca(2+) and K(+) currents. It remains unclear whether I(Na) is also altered. Right atrial appendages from patients with AF (n = 23) and in sinus rhythm (SR) (n = 79) were studied. Patch-clamp experiments in isolated atrial myocytes showed significantly reduced peak I(Na) density ( approximately 16%) in AF compared with SR, which was accompanied by a 26% lower expression of Nav1.5 (p < 0.05). In contrast, late I(Na) was significantly increased in myocytes from AF atria by approximately 26%. Ran (10 mumol/L) decreased late I(Na) by approximately 60% (p < 0.05) in myocytes from patients with AF but only by approximately 18% (p < 0.05) in myocytes from SR atria. Proarrhythmic activity was elicited in atrial trabeculae exposed to high [Ca(2+)](o) or isoprenaline, which was significantly reversed by Ran (by 83% and 100%, respectively). Increasing pacing rates from 0.5 to 3.0 Hz led to an increase in diastolic tension that could be significantly decreased by Ran in atria from SR and AF patients. Na(+) channels may contribute to arrhythmias and contractile remodeling in AF. Inhibition of I(Na) with Ran had antiarrhythmic effects and improved diastolic function.
