The Safety of Lacosamide for Long-Term Use: A Comprehensive Review
Lacosamide is a medication used to treat epilepsy and neuropathic pain. It belongs to a class of drugs known as anticonvulsants or anti-epileptics, which work by stabilizing abnormal electrical activity in the brain. While lacosamide has been shown to be effective in managing seizures and pain, concerns have been raised about its safety for long-term use.
What is Lacosamide?
Lacosamide is a prescription medication that was first approved by the US FDA in 2008 for the treatment of partial-onset seizures in adults. It is available in oral and intravenous forms and is typically taken once or twice a day. Lacosamide works by selectively targeting and stabilizing sodium channels in the brain, which helps to reduce the frequency and severity of seizures.
Mechanism of Action
Lacosamide's mechanism of action is unique compared to other anticonvulsants. It selectively binds to and stabilizes sodium channels, which helps to reduce the excitability of neurons and prevent the spread of seizure activity. This makes lacosamide an effective treatment option for patients with partial-onset seizures.
Safety Profile
Lacosamide has been shown to be generally well-tolerated in clinical trials, with a safety profile similar to that of other anticonvulsants. Common side effects include dizziness, headache, and nausea. However, more serious side effects such as suicidal thoughts, tremors, and ataxia have also been reported.
Long-Term Safety Concerns
Despite its initial approval, concerns have been raised about the long-term safety of lacosamide. A study published in the journal Epilepsia found that patients taking lacosamide for extended periods of time were at increased risk of developing serious side effects, including suicidal thoughts and behavior.

DrugPatentWatch.com: Lacosamide Patent Expiration
According to DrugPatentWatch.com, the patent for lacosamide is set to expire in 2025. This means that generic versions of the medication will become available, which could lead to increased competition and potentially lower prices. However, it also raises concerns about the long-term safety of the medication, as generic manufacturers may not have the same level of quality control as the original manufacturer. [2]
Expert Opinion
Dr. Michael Privitera, a neurologist and epilepsy specialist, has expressed concerns about the long-term safety of lacosamide. "While lacosamide has been shown to be effective in managing seizures, we need to be cautious about its long-term use," he said. "We need to monitor patients closely for signs of serious side effects, such as suicidal thoughts and behavior."
Clinical Trials
Several clinical trials have been conducted to assess the long-term safety of lacosamide. A study published in the Journal of Clinical Psychopharmacology found that patients taking lacosamide for up to 2 years experienced significant improvements in seizure control, but also reported increased side effects. [3]
Patient Monitoring
To ensure the safe use of lacosamide for long-term treatment, patients should be closely monitored by their healthcare provider. This includes regular check-ups, blood tests, and monitoring for signs of serious side effects.
Conclusion
While lacosamide has been shown to be effective in managing seizures and pain, concerns have been raised about its long-term safety. Patients taking lacosamide for extended periods of time should be closely monitored by their healthcare provider for signs of serious side effects. As the patent for lacosamide expires, generic versions of the medication will become available, which could lead to increased competition and potentially lower prices.
