What are the mechanisms behind Ranolazine?
Ranolazine is late Ina (inward sodium current) inhibitor in the cardiac muscle, which, in turn, reduces the amount of intracellular calcium. Lowering of calcium level leads to lusitropy (relaxation of miocardium) and reducing of diastolic wentricular wall tension. In simple words, it stimulates blood inflow to the heart. Thanks to this, the heart begins to function more efficiently. Also, as a result of Ranolazine’s effect, oxygen requirements reduce, which helps to mitigate such symptom of angina as feeling short of breath.
