• Safety and effectiveness have not been established
• In pediatric patients

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. …

• Advise the patient to read the FDA-approved patient labeling (Patient Information)
• Inform patients that ranolazine will not abate an acute angina episode
• Strong CY3PA Inhibitors, CYP3A Inducers, Liver Cirrhosis Inform patients that ranolazine should not be used with drugs that are strong CYP3A inhibitors (e.g., ketoconazole, clarithromycin, nefazodone, ritonavir) [(see Contraindications , Drug Interactions ]
• Inform patients that ranolazine should not be used with drugs that are inducers of CYP3A (e.g., rifampin, rifabutin, rifapentine, barbiturates, carbamazepine, phenytoin, St

• Ranolazine is contraindicated in patients: Taking strong inhibitors of CYP3A [see Drug Interactions ] Taking inducers of CYP3A [see Drug Interactions ] With liver cirrhosis [see Use in Specific Populations ] Strong CYP3A inhibitors (e.g., ketoconazole, clarithromycin, nelfinavir) CYP3A inducers (e.g., rifampin, phenobarbital, St

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. …

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 (CrCL1000 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 Q …

Most common adverse reactions (>4% and more common than with placebo) are dizziness, headache, constipation, nausea.

A total of 2018 patients with chronic angina were treated with ranolazine in controlled clinical trials. …

8.1 Pregnancy 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. …

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. …

Tómala en cuanto te acuerdes, salvo que falte poco para la siguiente. En ese caso, sáltate la olvidada. Nunca tomes dos dosis a la vez para compensar. Revisa tu prospecto, porque algunos medicamentos son distintos.
