Rivotril is a brand name for the drug clonazepam, which belongs to a class of medications called benzodiazepines. Benzodiazepines work by enhancing the activity of a chemical in the brain called gamma-aminobutyric acid (GABA). This calms excessive brain activity, which helps reduce seizures and symptoms of anxiety. https://www.griddixcat.com/blogs/12183/Understanding-Rivotril-10-mg-in-the-UK-Uses-Risks-and
