Controlled studies in angina patients have shown that trimetazidine increases coronary flow reserve, thereby delaying the onset of ischemia associated with exercise, limits rapid swings in blood pressure without any significant variations in heart rate, significantly decreases the frequency of angina attacks, and leads to a significant decrease in the use of nitrates.

It improves left ventricular function in diabetic patients with coronary heart disease. Recently, it has been shown to be effective in patients with heart failure of different etiologies.

Trimetazidine is described as the first cytoprotective anti-ischemic agent. It acts by directly counteracting all the major metabolic disorders occurring within the ischemic cell. The actions of trimetazidine include limitation of intracellular acidosis, correction of disturbances of transmembrane ion exchanges, and prevention of excessive production of free radicals.

Trimetazidine is usually prescribed as a long-term treatment of angina pectoris, and in some countries for tinnitus and dizziness. It is taken twice a day.

Trimetazidine has a high safety and tolerability profile. It has no known drug interactions.
