📄 Full prescribing information FDA SPL
🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE Ranolazine extended-release tablets are indicated for the treatment of chronic angina. Ranolazine extended-release tablets may be used with beta-blockers, nitrates, calcium channel blockers, anti-platelet therapy, lipid-lowering therapy, ACE inhibitors, and angiotensin receptor blockers. Ranolazine is an antianginal indicated for the treatment of chronic angina. ( 1 )
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION 500 mg twice daily and increase to 1000 mg twice daily, based on clinical symptoms ( 2.1 )
2.1Dosing Information Initiate ranolazine extended-release tablets dosing at 500 mg twice daily and increase to 1000 mg twice daily, as needed, based on clinical symptoms. Take ranolazine extended-release tablets with or without meals. Swallow ranolazine extended-release tablets whole; do not crush, break, or chew.
The maximum recommended daily dose of ranolazine extended-release tablets is 1000 mg twice daily. If a dose of ranolazine extended-release tablets is missed, take the prescribed dose at the next scheduled time; do not double the next dose.
2.2Dose Modification Dose adjustments may be needed when ranolazine is taken in combination with certain other drugs [see Drug Interactions ( 7.1 )] . Limit the maximum dose of ranolazine to 500 mg twice daily in patients on moderate CYP3A inhibitors such as diltiazem, verapamil, and erythromycin. Use of ranolazine with strong CYP3A inhibitors is contraindicated [see Contraindications ( 4 ), Drug Interactions ( 7.1 )].
Use of P-gp inhibitors, such ascyclosporine, may increase exposure to ranolazine. Titrate ranolazine based on clinical response [see Drug Interactions ( 7.1 )].
💊 Dosage Forms and Strengths ▾
3 DOSAGE FORMS AND STRENGTHS Ranolazine extended-release tablets are supplied as film-coated, biconvex, oblong-shaped, extended-release tablets in the following strengths: 500 mg tablets are white to off-white coloured, debossed with "296" and "U" on other side. 1000 mg tablets are pale orange coloured, debossed with "297" and "U" on other side. Extended-release tablets: 500 mg, 1000 mg ( 3 )
⛔ Contraindications ▾
4 CONTRAINDICATIONS Ranolazine is contraindicated in patients: Taking strong inhibitors of CYP3A [see Drug Interactions ( 7.1 )] Taking inducers of CYP3A [see Drug Interactions ( 7.1 )] With liver cirrhosis [see Use in Specific Populations ( 8.6 )] StrongCYP3A inhibitors (e.g., ketoconazole, clarithromycin, nelfinavir) ( 4 , 7.1 ) CYP3A inducers (e.g., rifampin, phenobarbital, St. John's wort) ( 4 , 7.1 ) Liver cirrhosis ( 4 , 8.6 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS QT interval prolongation: Can occur with ranolazine. Little data available on high doses, long exposure, use with QT interval-prolonging drugs, potassium channel variants causing prolonged QT interval, in patients with a family history of (or congenital) long QT syndrome, or in patients with known acquired QT interval prolongation. ( 5.1 ) Renal failure: Monitor renal function after initiation and periodically in patients with moderate to severe renal impairment (CrL<60 ml/min).
If acute renal failure develops, discontinue ranolazine.( 5.2 )
5.1QT Interval Prolongation Ranolazine blocks I Kr and prolongs the QTc interval in a dose-related manner. Clinical experience in an acute coronary syndrome population did not show an increased risk of proarrhythmia or sudden death [see Clinical Studies ( 14.2 )] . However, there is little experience with high doses (>1000 mg twice daily) or exposure, other QT-prolonging drugs, potassium channel variants resulting in a long QT interval, in patients with a family history of (or congenital) long QT syndrome, or in patients with known acquired QT interval prolongation.
5.2Renal Failure Acute renal failure has been observed in some patients with severe renal impairment (creatinine clearance [CrCL] <30 mL/min) while taking ranolazine. If acute renal failure develops (e.g., marked increase in serum creatinine associated with an increase in blood urea nitrogen [BUN]), discontinue ranolazine and treat appropriately [see Use in Specific Populations ( 8.7 )] . Monitor renal function after initiation and periodically in patients with moderate to severe renal impairment (CrCL <60 mL/min) for increases in serum creatinine accompanied by an increase in BUN.
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS Most common adverse reactions (>4% and more common than with placebo) are dizziness, headache, constipation, nausea. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Unichem Pharmaceuticals (USA), Inc., at 1-866-562-4616 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
6.1Clinical Trial Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. A total of 2018 patients with chronic angina were treated with ranolazine in controlled clinical trials. Of the patients treated with ranolazine, 1026 were enrolled in three double-blind, placebo-controlled, randomized studies (CARISA, ERICA, MARISA) of up to 12 weeks' duration.
In addition, upon study completion, 1251 patients received treatment with ranolazine in open-label, long-term studies; 1227 patients were exposed to ranolazine for more than 1 year, 613 patients for more than 2 years, 531 patients for more than 3 years, and 326 patients for more than 4 years. At recommended doses, about 6% of patients discontinued treatment with ranolazine because of an adverse event in controlled studies in angina patients compared to about 3% on placebo. The most common adverse events that led to discontinuation more frequently on ranolazine than placebo were dizziness (1.3% versus 0.1%), nausea (1% versus 0%), asthenia, constipation, and headache (each about 0.5% versus 0%).
Doses above 1000 mg twice daily are poorly tolerated. In controlled clinical trials of angina patients, the most frequently reported treatment-emergent adverse reactions (>4% and more common on ranolazine than on placebo) were dizziness (6.2%), headache (5.5%), constipation (4.5%), and nausea (4.4%).Dizziness may be dose-related. In open-label, long-term treatment studies, a similar adverse reaction profile was observed.
The following additional adverse reactions occurred at an incidence of 0.5 to 4.0% in patients treated with ranolazine and were more frequent than the incidence observed in placebo-treated patients: Cardiac Disorders – bradycardia, palpitations Ear and Labyrinth Disorders – tinnitus, vertigo Eye Disorders – blurred vision Gastrointestinal Disorders – abdominal pain, dry mouth, vomiting, dyspepsia General Disorders and Administrative Site Adverse Events – asthenia, peripheraledema Metabolism and Nutrition Disorders – anorexia Nervous System Disorders – syncope (vasovagal) Psychiatric Disorders – confusional state Renal and Urinary Disorders – hematuria Respiratory , Thoracic, and Mediastinal Disorders – dyspnea Skin and Subcutaneous Tissue Disorders – hyperhidrosis Vascular Disorders – hypotension, orthostatic hypotension Other (<0.5%) but potentially medically important adverse reactions observed more frequently with ranolazine than placebo treatment in all controlled studies included: angioedema, renal failure, eosinophilia, chromaturia, blood urea increased, hypoesthesia, paresthesia, tremor, pulmonary fibrosis, thrombocytopenia, leukopenia, and pancytopenia.
A large clinical trial in acute coronary syndrome patients was unsuccessful in demonstrating a benefit for ranolazine, but there was no apparent proarrhythmic effect in these high-risk patients [see Clinical Studies ( 14.2 )] . Laboratory Abnormalities: Ranolazine produces elevations of serum creatinine by 0.1 mg/dL, regardless of previous renal function, likely because of inhibition of creatinine's tubular secretion. In general, the elevation has a rapid onset, shows no signs of progression during long-term therapy, is reversible after discontinuation of ranolazine, and is not accompanied by changes in BUN.
In healthy volunteers, ranolazine 1000 mg twice daily had no effect upon the glomerular filtration rate. More marked and progressive increases in serum creatinine, associated with increases in BUN or pota…
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Moderate CYP3A inhibitors (e.g., diltiazem, verapamil, erythromycin): Limit ranolazine to 500 mg twice daily. ( 7.1 ) P-gp inhibitors (e.g., cyclosporine): Ranolazine exposure increased. Titrate ranolazine based on clinical response.
( 7.1 ) CYP3A substrates: Limit simvastatin to 20 mg when used with ranolazine. Doses of other sensitive CYP3A substrates (e.g., lovastatin) and CYP3A substrates with narrow therapeutic range (e.g., cyclosporine, tacrolimus, sirolimus) may need to be reduced with ranolazine. ( 7.2 ) OCT2 substrates: Limit the dose of metformin to 1700 mg daily when used with ranolazine 1000 mg twice daily.
Doses of other OCT2 substrates may require adjusted doses. ( 7.2 ) Drugs transported by P-gp (e.g., digoxin), or drugs metabolized by CYP2D6 (e.g., tricyclic antidepressants) may need reduced doses when used with ranolazine. ( 7.2 )
7.1Effects of Other Drugs on Ranolazine Strong CYP3A Inhibitors Do not use ranolazine with strong CYP3A inhibitors, including ketoconazole, itraconazole, clarithromycin, nefazodone, nelfinavir, ritonavir, indinavir, and saquinavir [see Contraindications ( 4 ), Clinical Pharmacology ( 12.3 )] . Moderate CYP3A Inhibitors Limit the dose of ranolazine to 500 mg twice daily in patients on moderate CYP3A inhibitors, including diltiazem, verapamil, erythromycin, fluconazole, and grapefruit juice or grapefruit-containing products [see Dosage and Administration ( 2.2 ), Clinical Pharmacology ( 12.3 )].
P-gp Inhibitors Concomitant use of ranolazine and P-gp inhibitors, such as cyclosporine, may result in increases in ranolazine concentrations. Titrate ranolazine based on clinical response in patients concomitantly treated with predominant P-gp inhibitors such as cyclosporine [see Dosage and Administration ( 2.2 )]. CYP3A Inducers Do not use ranolazine with CYP3A inducers such as rifampin, rifabutin, rifapentine, phenobarbital, phenytoin, carbamazepine, and St.
John's wort [see Contraindications ( 4 ), Clinical Pharmacology ( 12.3 )] .
7.2Effects of Ranolazine on Other Drugs Drugs Metabolized by CYP3A Limit the dose of simvastatin in patients on any dose of ranolazine to 20 mg once daily, when ranolazine is co-administered. Dose adjustment of other sensitive CYP3A substrates (e.g., lovastatin) and CYP3A substrates with a narrow therapeutic range (e.g., cyclosporine, tacrolimus, sirolimus) may be required as ranolazine may increase plasma concentrations of these drugs [see Clinical Pharmacology ( 12.3 )] . Drugs Transported by P-gp Concomitant use of ranolazine and digoxin results in increased exposure to digoxin.
The dose of digoxin may have to be adjusted [see Clinical Pharmacology ( 12.3 )]. Drugs Metabolized by CYP2D6 The exposure to CYP2D6 substrates, such as tricyclic antidepressants and antipsychotics, may be increased during co-administration with ranolazine, and lower doses of these drugs may be required. Drugs Transported by OCT2 In subjects with type 2 diabetes mellitus, concomitant use of ranolazine 1000 mg twice daily and metformin results in increased plasma levels of metformin.
When ranolazine 1000 mg twice daily is co-administered with metformin, metformin dose should not exceed 1700 mg/day. Monitor blood glucose levels and risks associated with high exposures of metformin. Metformin exposure was not significantly increased when given with ranolazine 500 mg twice daily [see Clinical Pharmacology ( 12.3 )].
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary There are no available data on ranolazine use in pregnant women to inform any drug-associated risks. Studies in rats and rabbits showed no evidence of fetal harm at exposures 4 times the maximum recommended human dose (MRHD) (see Data) . In the U.S. general population, the estimated background risk of major birth defects and of miscarriage of clinically recognized pregnancies is 2-4% and 15-20%, respectively.
Data Animal Data Embryofetal toxicity studies were conducted in rats and rabbits orally administered ranolazine during organogenesis. In rats, decreased fetal weight and reduced ossification were observed at doses (corresponding to 4-fold the AUC for the MRHD) that caused maternal weight loss. No adverse fetal effects were observed in either species exposed (AUC) to ranolazine at exposures (AUC) equal to the MRHD.
8.2Lactation Risk Summary There are no data on the presence of ranolazine in human milk, the effects on the breastfed infant, or the effects on milk production. However, ranolazine is present in rat milk [see Use in Specific Populations ( 8.1 )] . The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for ranolazine and any potential adverse effects on the breastfed infant from ranolazine or from the underlying maternal condition.
Adult female rats were administered ranolazine orally from gestation day 6 through postnatal day 20. No adverse effects on pup development, behavior, or reproduction parameters were observed at a maternal dosage level of 60 mg/kg/day (equal to the MHRD based on AUC). At maternally toxic doses, male and female pups exhibited increased mortality and decreased body weight, and female pups showed increased motor activity.
The pups were potentially exposed to low amounts of ranolazine via the maternal milk.
8.4Pediatric Use Safety and effectiveness have not been established in pediatric patients.
8.5Geriatric Use Of the chronic angina patients treated with ranolazine in controlled studies, 496 (48%) were ≥65 years of age, and 114 (11%) were ≥75 years of age. No overall differences in efficacy were observed between older and younger patients. There were no differences in safety for patients ≥65 years compared to younger patients, but patients ≥75 years of age on ranolazine, compared to placebo, had a higher incidence of adverse events, serious adverse events, and drug discontinuations due to adverse events.
In general, dose selection for an elderly patient should usually start at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease, or other drug therapy.
8.6Use in Patients with Hepatic Impairment Ranolazine is contraindicated in patients with liver cirrhosis. In a study of cirrhotic patients, the C max of ranolazine was increased 30% in cirrhotic patients with mild (Child-Pugh Class A) hepatic impairment, but increased 80% in cirrhotic patients with moderate (Child-Pugh Class B) hepatic impairment compared to patients without hepatic impairment. This increase was not enough to account for the 3-fold increase in QT prolongation seen in cirrhotic patients with mild to moderate hepatic impairment [see Clinical Pharmacology ( 12.2 )] .
8.7Use in Patients with Renal Impairment A pharmacokinetic study of ranolazine in subjects with severe renal impairment (CrCL <30 mL/min) was stopped when 2 of 4 subjects developed acute renal failure after receiving ranolazine 500 mg twice daily for 5 days (lead-in phase) followed by 1000 mg twice a day (1 dose in one subject and 11 doses in the other). Increases in creatinine, BUN, and potassium were observed in 3 subjects during the 500 mg lead-in phase. One subject required hemodialysis, while the other 2 subjects improved upon drug discontinuation [see Warnings and Precautions ( 5.2 )].

🆘 Overdosage ▾
10 OVERDOSAGE Hypotension, QT prolongation, bradycardia, myoclonic activity, severe tremor, unsteady gait/incoordination, dizziness, nausea, vomiting, dysphasia, and hallucinations have been seen in cases of oral overdose of ranolazine. In cases of extreme overdose of ranolazine fatal outcomes have been reported. In clinical studies, high intravenous exposure resulted in diplopia, paresthesia, confusion, and syncope.
In addition to general supportive measures, continuous ECG monitoring may be warranted in the event of overdose. Since ranolazine is about 62% bound to plasma proteins, hemodialysis is unlikely to be effective in clearing ranolazine.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action The mechanism of action of ranolazine's antianginal effects has not been determined. Ranolazine has anti-ischemic and antianginal effects that do not depend upon reductions in heart rate or blood pressure. It does not affect the rate-pressure product, a measure of myocardial work, at maximal exercise.
Ranolazine at therapeutic levels can inhibit the cardiac late sodium current (I Na ). However, the relationship of this inhibition to angina symptoms is uncertain. The QT prolongation effect of ranolazine on the surface electrocardiogram is the result of inhibition of I Kr , which prolongs the ventricular action potential.
12.2Pharmacodynamics Hemodynamic Effects Patients with chronic angina treated with ranolazine in controlled clinical studies had minimal changes in mean heart rate (<2 bpm) and systolic blood pressure (<3 mm Hg). Similar results were observed in subgroups of patients with CHF NYHA Class I or II, diabetes, or reactive airway disease, and in elderly patients. Electrocardiographic Effects Dose and plasma concentration-related increases in the QTc interval [see Warnings and Precautions ( 5.1 )], reductions in T wave amplitude, and, in some cases, notched T waves, have been observed in patients treated with ranolazine.
These effects are believed to be caused by ranolazine and not by its metabolites. The relationship between the change in QTc and ranolazine plasma concentrations is linear, with a slope of about 2.6 msec/1000 ng/mL, through exposures corresponding to doses several-fold higher than the maximum recommended dose of 1000 mg twice daily. The variable blood levels attained after a given dose of ranolazine give a wide range of effects on QTc.
At T max following repeat dosing at 1000 mg twice daily, the mean change in QTc is about 6 msec, but in the 5% of the population with the highest plasma concentrations, the prolongation of QTc is at least 15 msec. In cirrhotic subjects with mild or moderate hepatic impairment, the relationship between plasma level of ranolazine and QTc is much steeper [see Contraindications ( 4 )] . Age, weight, gender, race, heart rate, congestive heart failure, diabetes, and renal impairment did not alter the slope of the QTc-concentration relationship of ranolazine.
No proarrhythmic effects were observed on 7-day Holter recordings in 3162 acute coronary syndrome patients treated with ranolazine. There was a significantly lower incidence of arrhythmias (ventricular tachycardia, bradycardia, supraventricular tachycardia, and new atrial fibrillation) in patients treated with ranolazine (80%) versus placebo (87%), including ventricular tachycardia ≥3 beats (52% versus 61%). However, this difference in arrhythmias did not lead to a reduction in mortality, a reduction in arrhythmia hospitalization, or a reduction in arrhythmia symptoms.
12.3Pharmacokinetics 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 C max 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.
The apparent terminal half-life of ranolazine is 7 hours. 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, C max and AUC 0-τ 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. Absorption and Distribution 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 met…
