Ranolazine

Ranolazine is a medication used to treat chronic angina, which is chest pain caused by reduced blood flow to the heart. It works by improving the heart's energy use and reducing the oxygen demand during activity. Unlike some other heart medications, ranolazine doesn’t directly lower blood pressure or heart rate but helps the heart work more efficiently. This can lead to fewer chest pain episodes and improve quality of life for people with stable angina. It is usually prescribed when other treatments haven't fully controlled symptoms.
