RANEXA (Ranolazine ER) is a medication prescribed to treat chronic angina.Anginais a cardiovascular disease where certain arteries in the heart do not receive enough oxygen. People with angina have a higher risk of cardiac cell death and heart attack. Symptoms of angina include dizziness, fatigue, sweating, shortness of breath, and tightness and pain in the chest. It is unclear how RANEXA treats symptoms of angina. However, RANEXA is known to slow the movement of sodium ions through certain heart muscle cells. RANEXA does not decrease the heart rate or lower blood pressure.

Most patients start by taking one RANEXA 500 mg tablet twice daily. The dosage can be increased to 1000 mg twice daily based on symptoms and side effects.
RANEXA is known to prolong the QT interval, which is a measurement of the electrical conductivity of the heart. When combined with other drugs that prolong the QT interval, RANEXA can increase the potential for Torsades de Pointes (TdP), a potentially fatal heart arrhythmia. Your QT interval should be monitored while taking RANEXA. RANEXA has the potential for drug interactions with many medications. Review your medication list with your doctor and pharmacist before starting RANEXA or any new medications.
