Klonopin is the brand name for the medication clonazepam, which belongs to the benzodiazepine class of drugs. It is primarily prescribed to treat seizure disorders, panic disorders, and certain types of anxiety disorders. Clonazepam works by enhancing the effects of gamma-aminobutyric acid (GABA), a neurotransmitter in the brain that helps to calm excessive electrical nerve activity. By increasing GABA activity, Klonopin helps to reduce the frequency and severity of seizures and can also provide relief from panic attacks and anxiety symptoms.
