Ranolazine extended-release tablet may be used with beta-blockers, nitrates, calcium channel blockers, anti-platelet therapy, lipid-lowering therapy, ACE inhibitors, and angiotensin receptor blockers. Ranolazine extended-release tablet is an antianginal indicated for the treatment of chronic angina. ( 1 )
Dosage & Administration
2 DOSAGE AND ADMINISTRATION 500 mg twice daily and increase to 1000 mg twice daily, based on clinical symptoms ( 2.1 ) 2.1 Dosing Information Initiate ranolazine extended-release tablet dosing at 500 mg twice daily and increase to 1000 mg twice daily, as needed, based on clinical symptoms. Take ranolazine extended-release tablet with or without meals. Swallow ranolazine extended-release tablet whole; do not crush, break, or chew. The maximum recommended daily dose of ranolazine extended-release tablet is 1000 mg twice daily. If a dose of ranolazine extended-release tablet is missed, take the prescribed dose at the next scheduled time; do not double the next dose. 2.2 Dose Adjustments in Specific Populations Dose adjustments may be needed when ranolazine extended-release tablet is taken in combination with certain other drugs [see Drug Interactions (7.1) ] . Limit the maximum dose of ranolazine extended-release tablet to 500 mg twice daily in patients on moderate CYP3A inhibitors such as diltiazem, verapamil, and erythromycin. Use of ranolazine extended-release tablet 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 tablet. Titrate ranolazine extended-release tablet based on clinical response [see Drug Interactions (7.1) ].
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 Viona Pharmaceuticals Inc. at 1-888-304-5011 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 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 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, 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 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 potassium, indicating acute renal failure, have been reported after initiation of ranolazine 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. 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

Administration Instruct patients to swallow ranolazine extended-release tablet whole, with or without meals, and not to crush, break, or chew tablets. Inform patients that if a dose is missed, to take the usual dose at the next scheduled time. The next dose should not be doubled. Inform patients that doses of ranolazine higher than 1000 mg twice daily should not be used [see Dosage and Administration (2) ]. Advise patients to inform their physician of any other medications taken concurrently with ranolazine, including over-the-counter medications.
