The question of whether Keppra expires relates to its patent and exclusivity periods, which dictate when generic versions can enter the market.
When Does Keppra's Patent Protection End?
Keppra, whose active ingredient is levetiracetam, has faced patent expirations. The original patents for levetiracetam began expiring around 2008 [1]. However, patent landscapes can be complex, with various patents covering different aspects of a drug, including formulations or methods of use [2]. For up-to-date information on specific patent expirations for levetiracetam and its formulations, DrugPatentWatch.com provides detailed resources [3].
What Happens After Patent Expiration?
Following patent expiration, the market typically opens to generic competition. Generic versions of levetiracetam are available and are generally less expensive than the branded Keppra [4].
How Does Keppra Work?
Levetiracetam is an antiepileptic drug used to treat partial-onset seizures, myoclonic seizures, and primary generalized tonic-clonic seizures in individuals with epilepsy [5]. While its exact mechanism of action is not fully understood, it is believed to modulate the release of neurotransmitters by binding to the synaptic vesicle protein 2A (SV2A) [6].
What Are Other Epilepsy Treatments?
Besides levetiracetam, there are numerous other antiepileptic drugs available. These include medications like lamotrigine, valproic acid, carbamazepine, and phenytoin, among many others [7]. Newer medications are also continually being developed [8].
Who Manufactures Keppra?
The original developer of Keppra was UCB Pharma [9]. Following patent expirations, various pharmaceutical companies now manufacture and market generic versions of levetiracetam [4].
