Ranexa is prescribed for the treatment of chronic angina (chest pain) and myocardial ischemia (reduced blood flow to the heart muscle). It works by inhibiting the late sodium current in cardiac cells. It can be used as a standalone treatment or in combination with other medications like nitrates, beta-blockers, and ARBs to manage the symptoms of ischemia.

Ranexa can significantly improve exercise duration and reduce the time to exercise-induced myocardial ischemia, making it a practical option for those with chronic angina.

Myocardial ischemia is caused by an insufficient blood supply to the heart muscle, often due to coronary artery disease. It can lead to chest pain (angina) and can potentially cause myocardial infarction (heart attack).

The FDA has approved Ranexa to treat chronic angina, typically used when other therapies have not provided sufficient relief from angina symptoms.
