Ranolazine (ranolazine) — Uses, Dosage, Side Effects & Safety

Drug class: Cardio-Metabolic

Overview

Ranolazine is a prescription medication used to treat chronic angina (chest pain) in adults. It is typically prescribed when other medicines for angina are not effective enough or cannot be tolerated. Ranolazine works differently from other antianginal drugs by improving blood flow to help the heart work more efficiently, without significantly affecting heart rate or blood pressure. Ranolazine helps reduce the number and severity of angina attacks, allowing you to be more active and improve your quality of life. It is not intended for the immediate relief of acute chest pain. Patients should continue to use their fast-acting nitroglycerin for sudden angina episodes. Key points: Take ranolazine exactly as prescribed, do not crush or chew the tablets, and inform your healthcare provider about all other medications you are taking to avoid interactions.
