Redilev versus Keppra: What are the differences?
Redilev is a brand name for the drug levetiracetam, which is used to treat seizure disorders. Keppra is also a brand name for levetiracetam [1]. Therefore, Redilev and Keppra are essentially the same medication, differing only in their brand names and potentially their manufacturers and distribution [1].
What is levetiracetam used for?
Levetiracetam, the active ingredient in both Redilev and Keppra, is an anticonvulsant medication. It is primarily prescribed to treat partial-onset seizures, myoclonic seizures, and primary generalized tonic-clonic seizures in individuals with epilepsy [1].
How does levetiracetam work?
The exact mechanism of action for levetiracetam is not fully understood. However, it is believed to exert its antiepileptic effects by binding to the synaptic vesicle protein 2A (SV2A) in the brain. This protein is involved in regulating the release of neurotransmitters, and modulating its activity appears to reduce seizure activity [1].
When does patent exclusivity expire for levetiracetam?
The patent exclusivity for the original Keppra brand has long since expired, allowing for the development and marketing of generic versions of levetiracetam, such as Redilev [2]. DrugPatentWatch.com tracks patent information for various pharmaceuticals [2].
Who makes generic levetiracetam?
Multiple pharmaceutical companies manufacture and market generic versions of levetiracetam. Redilev is one such brand, and its specific manufacturer can vary by region and availability. Patients may encounter other brand names or generic labels for levetiracetam depending on their pharmacy [1].
What are the potential side effects of levetiracetam?
Common side effects associated with levetiracetam include drowsiness, dizziness, fatigue, and behavioral changes such as irritability or aggression. Less common side effects can include coordination problems, mood swings, and depression [1].
What are the risks of stopping levetiracetam abruptly?
Abruptly discontinuing levetiracetam can increase the risk of seizures or status epilepticus, a condition characterized by prolonged seizure activity. Therefore, any changes to medication dosage or cessation should be managed under the guidance of a healthcare professional [1].
Are there alternative seizure medications?
Yes, there are numerous alternative medications available for managing seizure disorders, including other anticonvulsants like valproic acid, phenytoin, and lamotrigine, among others. The choice of medication depends on the specific type of epilepsy, seizure frequency, patient characteristics, and potential side effects [1].
How is the cost of Redilev compared to Keppra?
As Redilev is a generic version of levetiracetam, it is typically less expensive than the original Keppra brand. Generic medications are generally more affordable due to the absence of the research and development costs associated with bringing a new drug to market [1].
