Why is this medication prescribed?

Ranolazine is a medication used to treat chronic angina, a type of chest pain that occurs when the heart muscle doesn’t receive enough blood flow and oxygen. It is typically prescribed when other angina medications, such as beta-blockers and calcium channel blockers, are not sufficient in controlling symptoms.

Ranolazine works by inhibiting certain sodium channels in the heart, which helps to reduce the amount of calcium entering the heart muscle cells. This, in turn, can lead to decreased oxygen demand by the heart and improved blood flow to the heart muscle.

How should this medicine be used?
