Antigen Description
Clonazepam is a benzodiazepine drug having anxiolytic, anticonvulsant, muscle relaxant, and hypnotic properties. It is marketed by Roche under the trade name Klonopin in the United States and Rivotril in Argentina, Australia, Brazil, Canada, Mexico and Europe. Other names such as Ravotril, Rivatril, Rivotril, Clonex, Paxam, Petril or Kriadex are known throughout the rest of the world.[citation needed] Clonazepam has an unusually long elimination half-life of 18–50 hours, making it generally considered to be among the long-acting benzodiazepines. Clonazepam is a chlorinated derivative of nitrazepam and therefore a chloro-nitrobenzodiazepine.
