Klonopin is the brand name for clonazepam, which is also a benzodiazepine medication like Ativan (lorazepam). Clonazepam is primarily prescribed to treat certain seizure disorders, including absence seizures and myoclonic seizures, as well as panic disorder and certain types of anxiety disorders.
Similar to other benzodiazepines, Klonopin works by enhancing the effects of GABA, a neurotransmitter that has a calming effect on the brain. This helps to reduce abnormal electrical activity in the brain, which can lead to seizures or exacerbate anxiety symptoms.
