Knowra Levetiracetam Levetiracetam Levetiracetam is an antiseizure medication used to treat focal-onset, myoclonic, and generalized tonic-clonic seizures. It binds synaptic vesicle protein 2A, though the full basis of its antiseizure effect remains uncertain.
Synaptic vesicle protein 2A : A membrane protein on synaptic vesicles that helps regulate neurotransmitter release. Levetiracetam binds this protein, its best-established molecular target.
Focal-onset seizure : A seizure that begins in networks confined to one cerebral hemisphere. Levetiracetam is used alone or with other medicines for this seizure type.
Lamotrigine : An antiseizure medication that also treats bipolar disorder and acts partly through voltage-gated sodium channels. It is a common alternative for focal seizures, with different titration and adverse-effect considerations.
Behavioral adverse effect : An unwanted change in mood, behavior, or mental state caused or worsened by treatment. Irritability, aggression, and mood changes are notable concerns during levetiracetam treatment.
Neurotransmitter release : The process by which neurons release chemical messengers from synaptic vesicles into synapses. Levetiracetam's binding to vesicle protein 2A is linked to altered release of neurotransmitters.
Myoclonic seizure : A brief seizure involving sudden, shock-like muscle jerks. Levetiracetam is used to treat myoclonic seizures, including those in juvenile myoclonic epilepsy.
Valproate : A broad-spectrum antiseizure medication also used for bipolar disorder and migraine prevention. It treats several seizure types but carries substantial reproductive risks that influence selection.
Somnolence : A state of excessive sleepiness or reduced alertness. Sleepiness and fatigue are common adverse effects, especially during treatment initiation.
Epileptic seizure : A transient episode caused by abnormal, excessive, or synchronized electrical activity in the brain. Levetiracetam reduces the likelihood of seizures without fully established details of how.
Generalized tonic-clonic seizure : A seizure involving loss of consciousness, body stiffening, and rhythmic jerking. Levetiracetam is used for primary generalized tonic-clonic seizures.
