Research Area: Cardiovascular Disease Biological Activity: Ranolazine(Ranexa), is an antianginal medication. Ranolazine is believed to have its effects via altering the trans-cellular late sodium current. It is by altering the intracellular sodium level that ranolazine affects the sodium-dependent calcium channels during myocardial ischemia in rabbits. Thus, ranolazine indirectly prevents the calcium overload that causes cardiac ischemia in rats. [1]
Biochem/physiol Actions pFOX (partial fatty acid oxidation) inhibitor, a new class of anti-anginal drugs, which inhibit fatty acid beta-oxidation and activates pyruvate dehydrogenase, thereby diverting the heart′s energy source from lipids to glucose, which requires less oxygen and helps maintain myocardiac function at times of ischemia
