Ranolazine is used to treat a certain type of chest pain (chronic angina). It decreases how often you may get chest pain and may help to increase your ability to exercise.Ranolazine works differently than other drugs for angina, so it can be used with your other angina medications (including nitrates, calcium channel blockers such as amlodipine, beta blockers such as metoprolol). It is thought to work by improving how well the heart uses oxygen so that it can do more work with less oxygen.
