Klonopin, the brand name for clonazepam, is a powerful prescription medication classified as a benzodiazepine. It is commonly used to treat seizure disorders, panic attacks, and anxiety. Clonazepam works by enhancing the activity of GABA (gamma-aminobutyric acid) in the brain, a neurotransmitter that slows down brain activity. This action produces a calming effect on the nervous system, helping to reduce seizures and manage anxiety symptoms.
