What's the difference between Benzodiazepine's and Dibenzodiazepines? Im looking at two different drugs here, Seroquel and Klonopin. Klonopine is from the benzo' family and Seroquel is a DIbenzodiazepine. what's the difference? Are the effects of these drugs similar? Not Seroquel and Klonopin in particular but Benzo vs. Dibenzo drugs in general.
