Clonazepam, commonly known by its brand name Klonopin, is a prescription medication used primarily to treat seizure disorders, panic disorders, and sometimes movement disorders like restless legs syndrome. As a member of the benzodiazepine class, clonazepam works by enhancing the effects of gamma-aminobutyric acid (GABA), a neurotransmitter that inhibits brain activity, leading to a calming effect on the nervous system. This action helps prevent and control seizures, reduce panic attacks, and alleviate muscle spasms.
