It is an antianginal drug that has a protective effect on the cellular structure and functions of various tissues or organs.
Within the group of organs that the drug covers is the myocardium , it protects it from the effects of hypoxia, ischemia or the metabolic disturbances that derive from them.
That is, it is a cardiac metabolism modulator drug which does not have direct hemodynamic effects.
Trimetazidine function
Trimetazidine is used for the long-term treatment of angina . Angina is chest pain that arises from the heart muscle when it does not receive enough oxygen.
It can cause the feeling of indigestion, fullness, pressure, or tightness in your chest that spreads to your arms or neck.
It works by producing a good supply of oxygen for the cells of the heart.
Trimetazidine makes better use of oxygen and energy in the cells of the heart. This helps decrease the number of times angina occurs.
Trimetazidine is also used for the treatment, prevention, control and improvement of the following symptoms:
- Severe pain in the chest
- Ringing in the ears.
- Inner ear problems.
However, trimetazidine is generally prescribed as a long-term treatment for angina pectoris.
Mechanism of action
Trimetazidine reduces beta-oxidation of fatty acids by blocking long-chain 3-ketoacyl-Co Atiolase, which increases glucose oxidation.
In an ischemic cell, the energy obtained during glucose oxidation requires less oxygen consumption than in the beta-oxidation process.
Trimetazidine and stable angina
The efficacy of trimetazidine as an antianginal drug has been evaluated in randomized, placebo-controlled studies.
It has also been studied as a treatment alone and in combination with beta blockers and calcium channel blockers.
Several studies have tested the efficacy of trimetazidine and have shown that this agent is at least as effective and better tolerated than hemodynamic agents.
In stable angina, it improves exercise tolerance and raises the ischemic threshold to an extent comparable to beta-blockers and calcium channel blockers.
The combination of trimetazidine and a beta blocker appears to be more effective than the combination of nitrates and a beta blocker.
The presence of trimetazidine improves symptoms in patients resistant to diltiazem or metoprolol.
