Ranolazine: Price, Dosage & Where to Buy

Ranolazine is an antianginal medicine used for chronic angina, a condition that causes chest pain or discomfort when the heart muscle does not receive enough oxygen. It is available as an extended-release oral medicine and has been available as a generic since 2013-07-29. In the United Kingdom, it requires a prescription.

Ranolazine extended-release tablets are indicated for the treatment of chronic angina. Chronic angina can cause recurring chest pain or discomfort because the heart muscle does not receive enough oxygen. Ranolazine may be used alongside beta-blockers, nitrates, calcium channel blockers, antiplatelet therapy, lipid-lowering therapy, ACE inhibitors, and angiotensin receptor blockers.

The medicine is intended for ongoing control of chronic angina rather than treatment of diabetes. A large clinical trial in acute coronary syndrome did not demonstrate a benefit for ranolazine.

The label lists ranolazine as oral granules of 1000 mg and as extended-release tablets of 500 mg and 1000 mg, including film-coated extended-release tablets. The usual starting dose is 500 mg twice daily. The label lists an increase to 1000 mg twice daily when needed according to clinical symptoms.

The label lists 1000 mg twice daily as the maximum recommended daily dose. The label lists a limit of 500 mg twice daily when ranolazine is used with moderate CYP3A inhibitors such as diltiazem, verapamil, or erythromycin.

The label states that tablets are used with or without meals and swallowed whole, not crushed, broken, or chewed. The label states that a missed dose is followed by the prescribed dose at the next scheduled time, without doubling the next dose.

Ranolazine is an antianginal medicine. It helps the heart muscle work more efficiently when oxygen supply is limited. Its main action is thought to involve reducing a late flow of sodium into heart muscle cells.

This can reduce the build-up of calcium inside those cells and ease some of the tension placed on the heart wall. By reducing this cellular stress, ranolazine can help control symptoms of chronic angina without depending mainly on lowering heart rate or blood pressure. Ranolazine can also prolong the QTc interval, so its effects on the heart’s electrical activity need to be considered, particularly alongside other medicines that prolong the QT interval.

There are no available data on ranolazine use in pregnant women to inform drug-associated risks. Studies in rats and rabbits showed no evidence of fetal harm at exposures 4 times the maximum recommended human dose, although decreased fetal weight and reduced ossification occurred in rats at exposures associated with maternal weight loss.

There are no data on ranolazine in human milk, effects on a breastfed infant, or effects on milk production. Pregnancy or breastfeeding should be discussed with a doctor or pharmacist.

A missed dose means the prescribed dose is omitted until the next scheduled time. The label states that the next scheduled dose should be used and that the next dose should not be doubled.

Regular timing helps maintain ongoing control of chronic angina. A pharmacist or doctor can provide advice if missed doses happen repeatedly or if angina symptoms worsen.

Store at 20°C to 25°C. Excursions are permitted between 15°C and 30°C. Keep the medicine protected as directed on the label, and do not use it if the blister is torn or broken.
