Ranolazine

Ranolazine — Uses and Benefits

Ranolazine is used mainly to manage chronic stable angina, a condition where reduced blood supply to the heart muscle causes recurring chest pain or discomfort.

WHAT THIS MEDICINE IS USED FOR

• Long-term treatment of chronic angina (chest pain)
• Usually given along with other heart medicines like beta-blockers, calcium channel blockers, or nitrates
• Helps reduce the frequency of angina episodes and improves exercise tolerance

HOW IT WORKS
