Keppra XR™ acts by targeting structures in the brain that are not affected directly by most other epilepsy medicines. This video tour* of the brain shows how signals are sent through the nervous system, what causes seizures, and how Keppra XR™ can help.
During a seizure, electrical signals in the brain cause the release of chemicals called neurotransmitters. These neurotransmitters help send messages between nerve cells (known as neurons). If the release of neurotransmitters happens too often or goes on for too long, there may be an overload in these electrical signals. This overload can result in a seizure.
Within the neurons, Keppra XR™ attaches to specific molecules (called SV2A). These molecules are found on the surfaces of tiny structures in the neurons called vesicles. The attachment of Keppra XR™ to the SV2A molecules may help reduce the abnormal spread of signals that can lead to a seizure.
