Ranexa 500 mg is a prescription medication that contains the active ingredient Ranolazine. It is indicated for the treatment of chronic angina pectoris, a condition caused by reduced blood flow to the heart muscle resulting in chest pain, pressure, or discomfort. Ranexa helps improve heart function efficiency and reduces the frequency of angina attacks without significantly affecting heart rate or blood pressure.

The usual starting adult dosage is typically 500 mg twice daily, which the doctor may gradually increase if necessary.
