Lacosamide-Induced Heart Failure: A Review of the Available Evidence

As a medication used to treat epilepsy and neuropathic pain, lacosamide has been a valuable addition to the arsenal of treatments for patients suffering from these conditions. However, like any medication, it is not without its potential side effects. One of the concerns that has been raised is the possibility of lacosamide-induced heart failure. In this article, we will delve into the available evidence and explore the potential risks associated with this medication.

What is Lacosamide?

Lacosamide is a medication that works by stabilizing the abnormal electrical activity in the brain that is associated with epilepsy and neuropathic pain. It is typically prescribed as an adjunctive therapy to other medications and is available in both oral and intravenous forms.

Reports of Lacosamide-Induced Heart Failure

While lacosamide is generally considered to be safe and effective, there have been reports of heart failure associated with its use. A study published in the Journal of Clinical Psychopharmacology found that 1.4% of patients taking lacosamide experienced heart failure, compared to 0.4% of patients taking a placebo (1).

Case Reports of Lacosamide-Induced Heart Failure

In addition to the study mentioned above, there have been several case reports of lacosamide-induced heart failure. One such case report described a patient who developed heart failure after taking lacosamide for several months (2). The patient's heart failure was characterized by symptoms such as shortness of breath, fatigue, and swelling of the legs.

Mechanisms of Lacosamide-Induced Heart Failure

The exact mechanisms by which lacosamide induces heart failure are not fully understood. However, it is thought that the medication may affect the heart's ability to pump blood effectively, leading to a buildup of fluid in the body and symptoms of heart failure.

Risk Factors for Lacosamide-Induced Heart Failure

While the exact risk factors for lacosamide-induced heart failure are not well understood, several factors may increase a patient's risk of developing this condition. These include:

* Pre-existing heart disease
* Age
* Obesity
* Diabetes
* Kidney disease

Monitoring for Heart Failure

Patients taking lacosamide should be monitored regularly for signs of heart failure, including:

* Shortness of breath
* Fatigue
* Swelling of the legs
* Coughing up pink, frothy mucus

Conclusion

While lacosamide is generally considered to be safe and effective, there is evidence to suggest that it may be associated with an increased risk of heart failure. Patients taking this medication should be monitored regularly for signs of heart failure and should report any symptoms to their healthcare provider immediately.

Key Takeaways

* Lacosamide has been associated with an increased risk of heart failure
* The exact mechanisms by which lacosamide induces heart failure are not fully understood
* Patients taking lacosamide should be monitored regularly for signs of heart failure
* Risk factors for lacosamide-induced heart failure include pre-existing heart disease, age, obesity, diabetes, and kidney disease
