Zapizolam is a pyridodiazepine drug, which is a benzodiazepine analogue of pyridotriazolodiazepine group.
It has sedative and anxiolytic effects similar to those produced by benzodiazepine derivatives, and has been sold illicitly as a designer drug.
A pyridotriazolodiazepine is a heterocyclic compound containing pyridine and triazole rings fused to a diazepine ring.
Pyridotriazolodiazepines forms the central structure of zapizolam. Zapizolam is poorly researched, but probably it is a sedative and/or anxiolytic, like other benzodiazepine derivatives, especially triazolobenzodiazepines (such as alprazolam).
