Ranolazine ([(+)N-(2,6-dimethylphenyl)-4(2-hydroxy-3-(2-methoxyphenoxy)-propyl)-1-piperazine acetamide dihydrochloride]) is an active piperazine derivative that was patented in 1986 and is available in an oral and intravenous form. Ranolazine is evidenced with anti-ischemic/antianginal properties in patients with chronic angina without clinically significant changes in heart rate or blood pressure.
Ranolazine is used for the treatment of angina (chronic chest pain). Researches show it also has potential use in cardiovascular conditions such as heart failure, acute and chronic myocardial ischemia, certain types of cardiac sodium channel gene mutations, and ventricular and supraventricular arrhythmias.
