Trimetazidine for Children: Safety and Dosage Considerations

Understanding Trimetazidine and Its Use in Children

Trimetazidine is a medication that has been used for many years in the treatment of various cardiovascular conditions, particularly angina pectoris. In recent years, there has been growing interest in the possible application of this drug in the pediatric population. In this article, we'll explore the safety and dosage considerations of trimetazidine for children, as well as discuss the potential benefits and risks associated with its use.

How Trimetazidine Works: The Science Behind the Drug

Trimetazidine primarily works by improving the efficiency of the heart's energy production. It does this by inhibiting the enzyme 3-ketoacyl-CoA thiolase, which plays a key role in the metabolism of fatty acids. By limiting the breakdown of fatty acids, trimetazidine shifts the heart's energy production towards glucose oxidation, which is a more efficient process that requires less oxygen. This ultimately helps to reduce the frequency and severity of angina attacks by ensuring that the heart has a more stable and efficient supply of energy.

Indications for Trimetazidine Use in Children

Although trimetazidine is primarily used to treat angina in adults, there are some instances where it may be considered for use in children. For example, trimetazidine has been used in pediatric patients with mitochondrial diseases, cardiomyopathies, and other conditions that affect the heart's energy metabolism. In these cases, trimetazidine may help to improve the heart's function and reduce the risk of complications associated with these conditions.

Determining the Appropriate Dosage for Children

As with any medication, it is essential to determine the appropriate dosage of trimetazidine for children based on factors such as age, weight, and the specific condition being treated. Currently, there is limited research on the optimal dosing of trimetazidine in the pediatric population. Therefore, it is crucial to consult with a healthcare professional who is experienced in treating children with trimetazidine to ensure that the correct dosage is prescribed.

Monitoring and Adjusting Treatment

Regular monitoring is essential when using trimetazidine in children to ensure that the medication is working effectively and safely. This may involve regular blood tests, electrocardiograms (ECGs), and other tests to assess the child's heart function and overall health. Based on the results of these tests, the child's healthcare provider may need to adjust the dosage of trimetazidine or consider alternative treatment options if necessary.

Potential Side Effects and Risks

As with any medication, there is a potential for side effects when using trimetazidine in children. Some of the most common side effects associated with trimetazidine include gastrointestinal disturbances, dizziness, headache, and fatigue. In some cases, trimetazidine may also cause more serious side effects such as heart rhythm disturbances, which may require medical attention.

Drug Interactions to Be Aware Of

It is important to be aware of potential drug interactions when using trimetazidine in children. Some medications, such as certain antiarrhythmics and antidepressants, may interact with trimetazidine and increase the risk of side effects. Therefore, it is crucial to inform the child's healthcare provider of all medications and supplements the child is taking to ensure that trimetazidine is used safely and effectively.

Considerations for Long-Term Use

Long-term use of trimetazidine in children may be necessary for some conditions, such as mitochondrial diseases or cardiomyopathies. In these cases, it is essential to closely monitor the child's overall health and heart function to ensure that the medication continues to be effective and safe. Additionally, regular follow-up appointments with the child's healthcare provider will help to identify any potential issues and make adjustments to the treatment plan as needed.

Discussing Trimetazidine with Your Child's Healthcare Provider

If you believe that trimetazidine might be a suitable treatment option for your child, it is essential to discuss this with their healthcare provider. They can help to determine whether trimetazidine is appropriate for your child's specific condition and provide guidance on the correct dosage and monitoring requirements. Additionally, they can also help to address any concerns or questions that you may have about the use of this medication in children.


In conclusion, trimetazidine may be a useful treatment option for certain heart-related conditions in children. However, it is essential to carefully consider the safety and dosage considerations associated with its use in the pediatric population. By working closely with your child's healthcare provider, you can ensure that trimetazidine is used safely and effectively to improve your child's heart health and overall well-being.
