Off-Label Use and Dosage (Pediatric)

Contraindications

RANEXA 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)]

Warnings

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, 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.

Renal Failure

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

Clinical Trials 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 2,018 patients with chronic angina were treated with ranolazine in controlled clinical trials. Of the patients treated with RANEXA, 1,026 were enrolled in three double-blind, placebo-controlled, randomized studies (CARISA, ERICA, MARISA) of up to 12 weeks' duration. In addition, upon study completion, 1,251 patients received treatment with RANEXA in open-label, long-term studies; 1,227 patients were exposed to RANEXA 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 RANEXA 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 RANEXA 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 RANEXA 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 RANEXA 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 RANEXA 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 RANEXA, but there was no apparent proarrhythmic effect in these high-risk patients [see Clinical Studies (14.2)].

Laboratory Abnormalities

RANEXA produces small reductions in hemoglobin A1c. RANEXA is not a treatment for diabetes. RANEXA 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 RANEXA, and is not accompanied by changes in BUN. In healthy volunteers, RANEXA 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 RANEXA in patients with severe renal impairment [see Warnings and Precautions (5.2), Use in Specific Populations (8.7)].

Postmarketing Experience

The following adverse reactions have been identified during postapproval use of RANEXA. 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 Tremor, paresthesia, abnormal coordination, 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. Psychiatric Disorders – hallucination Renal and Urinary Disorders – dysuria, urinary retention Skin and Subcutaneous Tissue Disorders – angioedema, pruritus, rash
