1. What Ontozry is and what it is used for
Ontozry contains the active substance cenobamate. It belongs to a group of medicines called ‘antiepileptics’. These medicines are used to treat epilepsy, a condition where someone has seizures or fits because of abnormal activity in the brain.
Ontozry is used in combination with other antiepileptic medicines in adult patients with epilepsy who have not been adequately controlled despite a history of treatment with at least 2 anti-epileptic products, to treat a type of epilepsy that has focal-onset seizures with or without secondary generalisation. Focal-onset seizures are those caused by abnormal brain activity starting in a part of the brain on one side, and secondary generalisation means that that the abnormal activity is spreading to both sides of the brain. The medicine can be used only in adults.
