At a glance
Ranolazine is an anti-anginal medication used for the treatment of chronic angina. It helps prevent new attacks of angina by decreasing the oxygen requirement of the heart through relaxation of heart muscle, but does not stop an acute attack once it has started.
Indications
- Chronic angina
Pharmacology
Ranolazine inhibits the late Na current, reducing intracellular Na concentrations and reversing Ca overload, which restores ventricular pump function and prevents ischaemia-induced arrhythmias. Its antianginal effects are not dependent on heart rate or blood pressure reduction. QT prolongation is caused by IKr inhibition.
