Rivotril is the brand name for clonazepam, a medication in the benzodiazepine class. It is commonly used to treat certain types of seizures and panic disorders. Clonazepam works by enhancing the activity of gamma-aminobutyric acid (GABA), a neurotransmitter that has a calming effect on the brain and nervous system. Rivotril is often prescribed to control and prevent seizures, particularly in conditions like epilepsy. It is effective in treating absence seizures, myoclonic seizures, and infantile spasms. It is also used to treat panic disorder, with or without agoraphobia, by reducing the frequency and severity of panic attacks.
