Keppra Introduction

Keppra (Keppra) is an anti-epileptic medication that is used to treat certain types of seizures in adults and children. It is used as an adjunct therapy to treat partial onset seizures and primary generalized tonic-clonic seizures. It works by reducing the activity of the neurons that cause seizures.

Uses for Keppra

Keppra is used to treat partial onset seizures and secondarily generalized tonic-clonic seizures in adults and children four years of age and older. It can also be used in patients who are at risk of further seizures.

Mechanism of Action

Keppra works by binding to a specific receptor in the brain, known as the SV2A receptor. This binding action reduces the amount of glutamate, an excitatory neurotransmitter, and increases the amount of GABA, an inhibitory neurotransmitter. This action is believed to reduce the activity of neurons that cause seizures.

How Long Does It Take To Work?

The effects of levetiracetam can be seen within one to two weeks of starting the medication. Approximately 50-70% of patients will experience a reduction in seizure frequency within six weeks of starting the medication.
