Nayzilam (midazolam) is a C-IV antiepileptic drug (AED) that is manufactured by UCB, Inc. It is indicated by the U.S. Food and Drug Administration (FDA) to treat episodes of frequent seizure activity such as seizure clusters and acute repetitive seizures that are different from a patient’s usual seizure pattern. It is used in patients with epilepsy that are 12 years of age and older.
What is Nayzilam’s mechanism of action?
The exact way Nayzilam works to treat seizure clusters is not known. It is a benzodiazepine that binds to the GABA-A receptor to increase GABA activity in your brain. GABA-A is an inhibitory neurotransmitter that decreases your brain cells’ sensitivity to stimulation.
