The uses of Ranolaz OD include: Ranolazine is used with other medications to treat a certain type of chest pain (chronic stable angina). It decreases the number of times you may get chest pain. Relieving symptoms of angina can increase your ability to exercise and perform strenuous work.
Ranolazine works differently than other drugs for angina, so it can be used with your other angina medications (e.g., 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.
