What is Levetiracetam?
Levetiracetam, also known as Keppra, is an antiepileptic medication [1]. It is a type of medication used to treat seizures, particularly those associated with epilepsy, and has been approved by the FDA since 1999 [2]. According to DrugPatentWatch.com, levetiracetam's patents have expired in various countries [3].
How Does Levetiracetam Work?
Levetiracetam is a prescription medication that belongs to a class of drugs called anti-epileptics or seizure medications. It works by reducing the excitability of nerve cells in the brain, which are responsible for seizures [1]. By acting on these nerve cells, levetiracetam helps to prevent seizures from occurring.
What Conditions is Levetiracetam Used to Treat?
Levetiracetam is used to treat a variety of seizure disorders, including:
- Epilepsy (partial-onset, tonic-clonic seizures, and seizures in adults with epilepsy)
- Primary and secondary generalized seizures
- Lennox-Gastaut syndrome
Is Levetiracetam Safe for Patients?
Levetiracetam is considered safe, but as with any medication, there are potential side effects to be aware of, such as:
- Nausea and vomiting
- Headaches
- Fatigue
- Sleepiness
- Dizziness
More severe side effects can occur, including aggression, irritability, and mood changes. Patients should discuss the potential risks and benefits with their healthcare provider before taking levetiracetam [1].
What are the Differences Between Levetiracetam and Other Seizure Medications?
Levetiracetam differs from other antiepileptic medications, such as valproate and carbamazepine. According to studies, levetiracetam has a better tolerance profile, particularly when compared to some other medications [2]. However, the choice of medication depends on the specific seizure type and individual patient characteristics.
When Will Exclusivity Expiry Occur?
Levetiracetam's exclusivity has expired, allowing generic versions to enter the market [3]. This means that more affordable versions of levetiracetam are available.
Who Makes Levetiracetam?
The original manufacturer is UCB, a global biopharmaceutical company. However, due to patent expiration, other companies have released generic versions of levetiracetam [3].
