Drug Details [pdf]

  • 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.

     

  • 2 DOSAGE AND ADMINISTRATION

    2.1 Dosing 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.

    2.2 Dose Modification

    Dose adjustments may be needed when ranolazine extended-release tablets are taken in combination with certain other drugs [see Drug Interactions (7.1)]. Limit the maximum dose of ranolazine extended-release tablets to 500 mg twice daily in patients on moderate CYP3A inhibitors such as diltiazem, verapamil, and erythromycin. Use of ranolazine extended-release tablets with strong CYP3A inhibitors is contraindicated [see Contraindications (4), Drug Interactions (7.1)]. Use of P-gp inhibitors, such as cyclosporine, may increase exposure to ranolazine extended-release tablets. Titrate ranolazine extended-release tablets based on clinical response [see Drug Interactions (7.1)].

  • 5 WARNINGS AND PRECAUTIONS

    5.1 QT Interval Prolongation

    Ranolazine blocks IKr 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, or 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.

    5.2 Renal Failure

    Acute renal failure has been observed in some patients with severe renal impairment (creatinine clearance [CrCL] <30 mL/min) while taking ranolazine extended-release tablets. If acute renal failure develops (e.g., marked increase in serum creatinine associated with an increase in blood urea nitrogen [BUN]), discontinue ranolazine extended-release tablets 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.

  • 6 ADVERSE REACTIONS

    6.1 Clinical 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 extended-release tablets, 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 extended-release tablets in open-label, long-term studies; 1227 patients were exposed to ranolazine extended-release tablets 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 extended-release tablets 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 extended-release tablets 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 extended-release tablets 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 extended-release tablets 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, peripheral edema

    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 extended-release tablets 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 extended-release tablets, but there was no apparent proarrhythmic effect in these high-risk patients [see Clinical Studies (14.2)].

    Laboratory Abnormalities

    Ranolazine extended-release tablets 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 extended-release tablets, and is not accompanied by changes in BUN. In healthy volunteers, ranolazine extended-release tablets 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 potassium, indicating acute renal failure, have been reported after initiation of ranolazine extended-release tablets in patients with severe renal impairment [see Warnings and Precautions (5.2), Use in Specific Populations (8.7)].

     

    6.2 Postmarketing Experience

    The following adverse reactions have been identified during postapproval use of ranolazine extended-release tablets. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure:

    Nervous System Disorders – Abnormal coordination, myoclonus, paresthesia, tremor, and other serious neurologic adverse events have been reported to occur, sometimes concurrently, in patients taking ranolazine. The onset of events was often associated with an increase in ranolazine dose or exposure. Many patients reported symptom resolution following drug discontinuation or dose decrease.

    Metabolism and Nutrition Disorders – Cases of hypoglycemia have been reported in diabetic patients on antidiabetic medication.

    Psychiatric Disorders – hallucination

    Renal and Urinary Disorders – dysuria, urinary retention

    Skin and Subcutaneous Tissue Disorders – angioedema, pruritus, rash

  • 7 DRUG INTERACTIONS

    7.1 Effects of Other Drugs on Ranolazine

    Strong CYP3A Inhibitors

    Do not use ranolazine extended-release tablets 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 extended-release tablets 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 extended-release tablets and P-gp inhibitors, such as cyclosporine, may result in increases in ranolazine concentrations. Titrate ranolazine extended-release tablets 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 extended-release tablets with CYP3A inducers such as rifampin, rifabutin, rifapentine, phenobarbital, phenytoin, carbamazepine, and St. John's wort [see Contraindications (4), Clinical Pharmacology (12.3)].

     

    7.2 Effects of Ranolazine on Other Drugs

    Drugs Metabolized by CYP3A

    Limit the dose of simvastatin in patients on any dose of ranolazine extended-release tablets 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 extended-release tablets 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 extended-release tablets, and lower doses of these drugs may be required.

  • SPL UNCLASSIFIED SECTION

    Drugs Transported by OCT2

    In subjects with type 2 diabetes mellitus, concomitant use of ranolazine extended-release tablets 1000 mg twice daily and metformin results in increased plasma levels of metformin. When ranolazine extended-release tablets 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 extended-release tablets 500 mg twice daily [see Clinical Pharmacology (12.3)].

     

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary

    There are no available data on ranolazine extended-release tablets 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.

     

    8.2 Lactation

    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 extended-release tablets and any potential adverse effects on the breastfed infant from ranolazine extended-release tablets 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.

     

    8.4 Pediatric Use

    Safety and effectiveness have not been established in pediatric patients. 

     

    8.5 Geriatric Use

    Of the chronic angina patients treated with ranolazine extended-release tablets 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 extended-release tablets, 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.

    8.6 Use in Patients with Hepatic Impairment

    Ranolazine extended-release tablets are contraindicated in patients with liver cirrhosis. In a study of cirrhotic patients, the Cmax 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)].

     

    8.7 Use in Patients with Renal Impairment

    A pharmacokinetic study of ranolazine extended-release tablets in subjects with severe renal impairment (CrCL <30 mL/min) was stopped when 2 of 4 subjects developed acute renal failure after receiving ranolazine extended-release tablets 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)]. Monitor renal function periodically in patients with moderate to severe renal impairment. Discontinue ranolazine extended-release tablets if acute renal failure develops.

    In a separate study, Cmax was increased between 40% and 50% in patients with mild, moderate, or severe renal impairment compared to patients with no renal impairment, suggesting a similar increase in exposure in patients with renal failure independent of the degree of impairment. The pharmacokinetics of ranolazine has not been assessed in patients on dialysis.

    8.8 Use in Patients with Heart Failure

    Heart failure (NYHA Class I to IV) had no significant effect on ranolazine pharmacokinetics. Ranolazine extended-release tablets had minimal effects on heart rate and blood pressure in patients with angina and heart failure NYHA Class I to IV. No dose adjustment of ranolazine extended-release tablets are required in patients with heart failure.

     

    8.9 Use in Patients with Diabetes Mellitus

    A population pharmacokinetic evaluation of data from angina patients and healthy subjects showed no effect of diabetes on ranolazine pharmacokinetics. No dose adjustment is required in patients with diabetes.

    Ranolazine extended-release tablets produces small reductions in HbA1c in patients with diabetes, the clinical significance of which is unknown. Ranolazine extended-release tablets should not be considered a treatment for diabetes.

  • 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 extended-release tablets. In cases of extreme overdose of ranolazine extended-release tablets 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

  • 11 DESCRIPTION

    Ranolazine extended-release tablets are available as a film-coated, non-scored, extended-release tablet for oral administration.

    Ranolazine is a racemic mixture, chemically described as 1-piperazineacetamide, N  (2,6-dimethylphenyl)-4-[2-hydroxy-3-(2-methoxyphenoxy)propyl]-, (±)-. It has an empirical formula of C24H33N3O4, a molecular weight of 427.54 g/mole, and the following structural formula:

    Chemical Structure

    Ranolazine is a white to off-white crystalline powder. Ranolazine is soluble in dichloromethane and methanol; sparingly soluble in tetrahydrofuran and acetonitrile slightly soluble in toluene.

    Ranolazine extended-release tablets contain 500 mg of ranolazine and the following inactive ingredients: hypromellose, macrogol/PEG 4000, magnesium stearate, methacrylic acid and ethyl acrylate copolymer (1:1) Type A, microcrystalline cellulose, polysorbate 80, polyvinyl alcohol, sodium hydroxide, sodium lauryl sulfate, talc and titanium dioxide.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism 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 (INa). 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 IKr, which prolongs the ventricular action potential.

     

    12.2 Pharmacodynamics

    Hemodynamic Effects

    Patients with chronic angina treated with ranolazine extended-release tablets 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 extended-release tablets. 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 Tmax 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 extended-release tablets. There was a significantly lower incidence of arrhythmias (ventricular tachycardia, bradycardia, supraventricular tachycardia, and new atrial fibrillation) in patients treated with ranolazine extended-release tablets (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.

     

    12.3 Pharmacokinetics

    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. The apparent terminal half-life of ranolazine is 7 hours. Steady state is generally achieved within 3 days of twice-daily dosing with ranolazine extended-release tablets. 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.

     

    Absorption and Distribution

    After oral administration of ranolazine extended-release tablets, peak plasma concentrations of ranolazine are reached between 2 and 5 hours. After oral administration of 14C-ranolazine as a solution, 73% of the dose is systemically available as ranolazine or metabolites. The bioavailability of ranolazine from ranolazine extended-release 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 extended-release tablets may be taken without regard to meals. Over the concentration range of 0.25 to 10 µg/mL, ranolazine is approximately 62% bound to human plasma proteins.

     

    Metabolism and Excretion

    Ranolazine is metabolized mainly by CYP3A and, to a lesser extent, by CYP2D6. Following a single oral dose of ranolazine solution, approximately 75% of the dose is excreted in urine and 25% in feces. Ranolazine is metabolized rapidly and extensively in the liver and intestine; less than 5% is excreted unchanged in urine and feces. The pharmacologic activity of the metabolites has not been well characterized. After dosing to steady state with 500 mg to 1500 mg twice daily, the four most abundant metabolites in plasma have AUC values ranging from about 5 to 33% that of ranolazine, and display apparent half-lives ranging from 6 to 22 hours.

    Drug Interactions

    Effect of Other Drugs on Ranolazine

    In vitro data indicate that ranolazine is a substrate of CYP3A and, to a lesser degree, of CYP2D6. Ranolazine is also a substrate of P-glycoprotein.

    Strong CYP3A Inhibitors

    Plasma levels of ranolazine with ranolazine extended-release tablets 1000 mg twice daily are increased by 220% when co-administered with ketoconazole 200 mg twice daily [see Contraindications (4)].

    Moderate CYP3A Inhibitors

    Plasma levels of ranolazine with ranolazine extended-release tablets 1000 mg twice daily are increased by 50 to 130% by diltiazem 180 to 360 mg, respectively. Plasma levels of ranolazine with ranolazine extended-release tablets 750 mg twice daily are increased by 100% by verapamil 120 mg three times daily [see Drug Interactions (7.1)].

    Weak CYP3A Inhibitors

    The weak CYP3A inhibitors simvastatin (20 mg once daily) and cimetidine (400 mg three times daily) do not increase the exposure to ranolazine in healthy volunteers.

    CYP3A Inducers

    Rifampin 600 mg once daily decreases the plasma concentrations of ranolazine (1000 mg twice daily) by approximately 95% [see Contraindications (4)].

    CYP2D6 Inhibitors

    Paroxetine 20 mg once daily increased ranolazine concentrations by 20% in healthy volunteers receiving ranolazine extended-release tablets 1000 mg twice daily. No dose adjustment of ranolazine extended-release tablets is required in patients treated with CYP2D6 inhibitors.

    Digoxin

    Plasma concentrations of ranolazine are not significantly altered by concomitant digoxin at 0.125 mg once daily.

    Effect of Ranolazine on Other Drugs

    In vitro ranolazine and its O-demethylated metabolite are weak inhibitors of CYP3A and moderate inhibitors of CYP2D6 and P-gp. In vitro ranolazine is an inhibitor of OCT2

    CYP3A Substrates

    The plasma levels of simvastatin, a CYP3A substrate, and its active metabolite are increased by 100% in healthy volunteers receiving 80 mg once daily and ranolazine extended-release tablets 1000 mg twice daily [see Drug Interactions (7.2)].

    Mean exposure to atorvastatin (80 mg daily) is increased by 40% following co-administration with ranolazine extended-release tablets (1000 mg twice daily) in healthy volunteers. However, in one subject the exposure to atorvastatin and metabolites was increased by ~400% in the presence of ranolazine extended-release tablets.

    Diltiazem

    The pharmacokinetics of diltiazem is not affected by ranolazine in healthy volunteers receiving diltiazem 60 mg three times daily and ranolazine extended-release tablets 1000 mg twice daily.

    P-gp Substrates

    Ranolazine increases digoxin concentrations by 50% in healthy volunteers receiving ranolazine extended-release tablets 1000 mg twice daily and digoxin 0.125 mg once daily [see Drug Interactions (7.2)].

    CYP2D6 Substrates

    Ranolazine extended-release tablets 750 mg twice daily increases the plasma concentrations of a single dose of immediate release metoprolol (100 mg), a CYP2D6 substrate, by 80% in extensive CYP2D6 metabolizers with no need for dose adjustment of metoprolol. In extensive metabolizers of dextromethorphan, a substrate of CYP2D6, ranolazine inhibits partially the formation of the main metabolite dextrorphan.

    OCT2 Substrates

    In subjects with type 2 diabetes mellitus, the exposure to metformin is increased by 40% and 80% following administration of ranolazine 500 mg twice daily and 1000 mg twice daily, respectively. If co-administered with ranolazine extended-release tablets 1000 mg twice daily, do not exceed metformin doses of 1700 mg/day [see Drug Interactions (7.2)].

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    Ranolazine tested negative for genotoxic potential in the following assays: Ames bacterial mutation assay, Saccharomyces assay for mitotic gene conversion, chromosomal aberrations assay in Chinese hamster ovary (CHO) cells, mammalian CHO/HGPRT gene mutation assay, and mouse and rat bone marrow micronucleus assays.

    There was no evidence of carcinogenic potential in mice or rats. The highest oral doses used in the carcinogenicity studies were 150 mg/kg/day for 21 months in rats (900 mg/m2/day) and 50 mg/kg/day for 24 months in mice (150 mg/m2/day). These maximally tolerated doses are 0.8 and 0.1 times, respectively, the daily maximum recommended human dose (MRHD) of 2000 mg on a surface area basis. A published study reported that ranolazine promoted tumor formation and progression to malignancy when given to transgenic APC (min/+) mice at a dose of 30 mg/kg twice daily [see References (15)].

    The clinical significance of this finding is unclear.

    In male and female rats, oral administration of ranolazine that produced exposures (AUC) approximatelty 3-fold or 5-fold higher, respectively, than the MRHD had no effect on fertility.

     

  • 14 CLINICAL STUDIES

    14.1 Chronic Stable Angina

    CARISA (Combination Assessment of Ranolazine In Stable Angina) was a study in 823 chronic angina patients randomized to receive 12 weeks of treatment with twice-daily ranolazine extended-release tablets 750 mg, 1000 mg, or placebo, who also continued on daily doses of atenolol 50 mg, amlodipine 5 mg, or diltiazem CD 180 mg. Sublingual nitrates were used in this study as needed.

    In this trial, statistically significant (p <0.05) increases in modified Bruce treadmill exercise duration and time to angina were observed for each ranolazine extended-release tablets dose versus placebo, at both trough (12 hours after dosing) and peak (4 hours after dosing) plasma levels, with minimal effects on blood pressure and heart rate. The changes versus placebo in exercise parameters are presented in Table 1. Exercise treadmill results showed no increase in effect on exercise at the 1000 mg dose compared to the 750 mg dose.

    Tolerance to ranolazine extended-release tablets did not develop after 12 weeks of therapy. Rebound increases in angina, as measured by exercise duration, have not been observed following abrupt discontinuation of ranolazine extended-release tablets.

    Ranolazine extended-release tablets has been evaluated in patients with chronic angina who remained symptomatic despite treatment with the maximum dose of an antianginal agent. In the ERICA (Efficacy of Ranolazine In Chronic Angina) trial, 565 patients were randomized to receive an initial dose of ranolazine extended-release tablets 500 mg twice daily or placebo for 1 week, followed by 6 weeks of treatment with ranolazine extended-release tablets 1000 mg twice daily or placebo, in addition to concomitant treatment with amlodipine 10 mg once daily. In addition, 45% of the study population also received long-acting nitrates. Sublingual nitrates were used as needed to treat angina episodes. Results are shown in Table 3. Statistically significant decreases in angina attack frequency (p=0.028) and nitroglycerin use (p=0.014) were observed with ranolazine extended-release tablets compared to placebo. These treatment effects appeared consistent across age and use of long-acting nitrates.

    Gender

    Effects on angina frequency and exercise tolerance were considerably smaller in women than in men. In CARISA, the improvement in Exercise Tolerance Test (ETT) in females was about 33% of that in males at the 1000 mg twice-daily dose level.

    In ERICA, where the primary endpoint was angina attack frequency, the mean reduction in weekly angina attacks was 0.3 for females and 1.3 for males.

    Race

    There were insufficient numbers of non-Caucasian patients to allow for analyses of efficacy or safety by racial subgroup.

    14.2 Lack of Benefit in Acute Coronary Syndrome

    In a large (n=6560) placebo-controlled trial (MERLIN-TIMI 36) in patients with acute coronary syndrome, there was no benefit shown on outcome measures. However, the study is somewhat reassuring regarding proarrhythmic risks, as ventricular arrhythmias were less common on ranolazine [see Clinical Pharmacology (12.2)], and there was no difference between ranolazine extended-release tablets and placebo in the risk of all-cause mortality (relative risk ranolazine:placebo 0.99 with an upper 95% confidence limit of 1.22).

    What is chronic angina?

    Chronic angina means pain or discomfort in the chest, jaw, shoulder, back, or arm that keeps coming back. There are other possible signs and symptoms of angina including shortness of breath. Angina usually comes on when you are active or under stress. Chronic angina is a symptom of a heart problem called coronary heart disease (CHD), also known as coronary artery disease (CAD). When you have CHD, the blood vessels in your heart become stiff and narrow. Oxygen-rich blood cannot reach your heart muscle easily. Angina comes on when too little oxygen reaches your heart muscle.
