Levetiracetam: Generic, Epilepsy Uses, Warnings, Side Effects, Dosage

Generic Name: levetiracetam

Brand and Other Names: Keppra, Keppra XR, Spritam, Elepsia

Drug Class: SV2A Ligands

What is levetiracetam, and what is it used for?

Levetiracetam is an antiepileptic drug used to treat certain types of seizures in adult and pediatric epileptic patients. Levetiracetam is a novel anticonvulsant drug chemically unrelated to any of the other existing anticonvulsant drugs. Levetiracetam has a better safety profile than other anticonvulsants, and interactions with fewer drugs, making it a preferred therapy.

The exact mechanism of levetiracetam’s anticonvulsant effects is not clear. Seizures are caused by abnormal bursts of electrical activity in the brain. Levetiracetam is thought to prevent the spread of seizure activity by preventing the synchronization of burst firing of nerve cells (neurons), without affecting normal neuronal excitability and neurotransmission.

Levetiracetam binds to a unique protein on the membrane of synaptic vesicles known as synaptic vesicle protein 2A (SV2A). Synapse is the junction between two nerve cells in which synaptic vesicles release chemicals (neurotransmitters) to conduct electrical impulses. SV2A regulates the neurotransmitter release, and by binding to SV2A, levetiracetam decreases the release of glutamate, an excitatory neurotransmitter.

Levetiracetam blocks the release of glutamate by also inhibiting N-type calcium channels, which prevents the influx of calcium into the neurons and inhibits action potential. Levetiracetam does not directly have an effect on gamma-aminobutyric acid (GABA), the major inhibitory neurotransmitter in the brain, but appears to increase GABA activity by blocking the negative modulators of GABA.

Levetiracetam is used to treat the following types of seizures in both adults and children:

  • Myoclonic seizures, a type that causes brief jerks of a muscle or groups of muscles
  • Partial onset seizures, a type that begins in only one part of the brain
  • Primary generalized tonic-clonic seizures, a type that starts on both sides of the brain and causes violent muscle contractions and loss of consciousness
  • Neonatal seizures (orphan designation), that occur in newborn babies

Warnings

  • Do not administer levetiracetam to patients hypersensitive to it or any of its components
  • Antiepileptic drugs, including levetiracetam increases the risk of suicidal thoughts and behavior; caregivers should be advised to monitor the patient for onset or worsening of depression or unusual changes in mood or behavior
  • As with most antiepileptic drugs, levetiracetam should be withdrawn gradually because of the risk of increased seizure frequency and status epilepticus, a state of prolonged seizure lasting longer than five minutes
  • Drowsiness and weakness may occur, especially within the first 4 weeks of treatment; patient must be advised not to drive or operate heavy machinery until any potential adverse drug effects can be gauged
  • Levetiracetam may cause psychiatric reactions such as aggression, anxiety, irritability and personality disorder; monitor and reduce dose or discontinue if necessary; patient and the caregivers must be counseled appropriately
  • Levetiracetam may cause serious skin reactions, including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN)
  • Drug rash with eosinophilia and systemic syndrome (DRESS), a severe drug reaction has been known to occur with levetiracetam use
  • Can cause blood abnormalities, including decrease in different types of blood cells
  • Can cause severe allergic reaction (anaphylaxis)
  • Physiological changes during pregnancy may gradually decrease drug concentration in blood, particularly during the 3rd trimester; dose adjustments may be required
  • Levetiracetam must be used with caution in patients with impaired kidney function
