The place of ranolazine in modern pharmacotherapy of chronic coronary syndrome. Own experience Review article
Main Article Content
Abstract
Ranolazine is an antianginal drug with a multifaceted mechanism of action that complements the effects of conventional pharmacotherapy for chronic coronary syndrome. The primary mechanism of its action stems from the inhibition of the late sodium current in the cardiomyocyte cell membrane. This results in improved myocardial relaxation and compliance, thereby reducing the frequency of observed arrhythmias. The specific antiarrhythmic mechanism of ranolazine prolongs the action potential duration and decreases the electrical excitability of cardiac muscle cells. Additionally, ranolazine exerts a cardioprotective effect under ischemic conditions. It inhibits β-oxidation of fatty acids, leading to a predominance of glucose metabolism. The drug is well-tolerated by patients, and its efficacy led to its inclusion in 2018 in the classification of medications used for supraventricular and ventricular arrhythmias.
