Heart Disease Home > Ranexa Uses
Adults who have chronic angina (chest pain) may be able to prevent angina attacks by using Ranexa on a daily basis. This prescription medication is not meant for use in people who have only periodic angina, as it does not help treat an attack that has already started. It is approved only for preventing angina attacks.
What Is Ranexa Used For?Ranexa® (ranolazine) is a prescription chronic angina (chest pain) medication. It is taken twice a day to help prevent angina attacks.
What Is Angina?Angina is usually caused by coronary artery disease (also known as coronary heart disease), a condition in which the small blood vessels that supply blood to the heart become too narrow to adequately supply the heart with enough blood and oxygen.
Many of the treatments for chronic angina affect the heart rate and blood pressure, often causing dangerous or intolerable side effects. In addition, nitroglycerin medications, which are often used for angina treatment, typically cause headaches and cannot be used around-the-clock or else they become ineffective.
Ranexa works differently than other angina medications and does not affect the heart rate or blood pressure. It stays effective when used around-the-clock and has a low risk for headaches.
However, Ranexa does not work quickly enough to stop an attack of angina that is already occurring. Instead, it is taken on a daily basis to help prevent angina attacks. In that sense, Ranexa is not appropriate for people that have only occasional or rare episodes of angina. Ranexa can be taken in combination with any of the usual drugs used to treat angina.
