Klonopin, the brand name for clonazepam, is a prescription medication classified as a benzodiazepine, a group of drugs known for their calming effects on the brain and nervous system. Klonopin is primarily used to treat seizure disorders, panic attacks, and anxiety disorders. It works by enhancing the effects of gamma-aminobutyric acid (GABA), a neurotransmitter in the brain that slows down nerve activity, leading to a sense of relaxation and reduced nervous system activity.
