Pivoxazepam is a drug which is a benzodiazepine derivative. It is the pivalate (2,2-dimethylpropanoate) ester of oxazepam.[1] It has sedative and anxiolytic actions like those of other benzodiazepines. Compared to its parent drug, oxazepam, pivoxazepam is more rapidly absorbed and slightly more sedative.
