Ranolazine 1000mg ER

Uses of Ranolazine 1000mg ER

• Chronic Angina: Helps manage the symptoms of chronic angina by improving blood flow to the heart.
• Adjunctive Therapy: Used in combination with other medications like nitrates, beta-blockers, or calcium channel blockers to manage angina.
• Improved Exercise Tolerance: Increases exercise tolerance by reducing chest pain and enhancing heart function.

How Does Ranolazine 1000mg ER Work?

Ranolazine works by inhibiting certain sodium channels in the heart, reducing the amount of sodium that enters heart cells. This decreases the oxygen demand of the heart and improves the efficiency of the heart muscle, helping to reduce angina. The extended-release formulation ensures a steady delivery of the drug, maintaining consistent symptom relief throughout the day.
