Rivotril, the brand name for clonazepam, is a prescription medication belonging to the benzodiazepine class. It is primarily used to treat seizure disorders and panic disorders. Rivotril is commonly prescribed for the treatment of epilepsy, specifically for certain types of seizures such as absence seizures, myoclonic seizures, and Lennox-Gastaut syndrome. It is also used to manage panic disorders and anxiety. Clonazepam works by enhancing the activity of gamma-aminobutyric acid (GABA), a neurotransmitter in the brain that helps to calm nervous activity, thus reducing the severity and frequency of seizures and anxiety.
