Description

Ranolazine ER 500 mg tablet is an antianginal medication used to treat chronic angina, a condition characterized by chest pain due to reduced blood flow to the heart. It works by improving blood flow to the heart muscle, thus helping to reduce the frequency and severity of angina attacks.

Ranolazine’s mechanism of action is unique as it works by inhibiting the late phase of the inward sodium current during cardiac repolarization, which leads to a reduction in intracellular calcium overload. This helps to decrease myocardial oxygen demand and improve overall heart function.

The 500 mg tablet is typically taken twice daily, with or without food, and reduces the risk of heart-related events. Common side effects include dizziness, headache, constipation, and nausea. Caution should be exercised to patients with liver problems or those taking medications that affect its metabolism, as drug interactions can occur.
