This medication is prescribed to address these core neurological challenges, though certain pediatric labeling information is restricted due to marketing exclusivity.

How SODIUM OXYBATE Works

Although its exact mechanism is unknown, this drug works by acting as a central nervous system depressant and is the sodium salt of a GABA metabolite called gamma-hydroxybutyrate. It is hypothesized to produce its effects through GABA B actions at specific neurons, including those that are noradrenergic, dopaminergic, and thalamocortical.
