Sodium oxybate is the sodium salt of gamma-hydroxybutyrate (GHB), an endogenous metabolite of gamma-aminobutyric acid (GABA) a major inhibitory neurotransmitter. Evidence suggests a role for GHB as a neuromodulator/neurotransmitter. Under endogenous conditions and concentrations, and depending on the cell group affected, GHB may increase or decrease neuronal activity by inhibiting the release of neurotransmitters that are co-localised with GHB. After exogenous administration, most of the observed behavioural effects appear to be mediated via the activity of GHB at GABA(B) receptors, as long as the concentration is sufficient to elicit binding, which does not happen at endogenous concentrations. Xyrem (sodium oxybate) oral solution is indicated for the treatment of cataplexy in narcolepsy and excessive daytime sleepiness (EDS) in narcolepsy.

Curator's Comment: Sodium oxybate (sodium salt of gamma-hydroxybutyrate (GHB) was first described as a possible precursor of GABA that could cross the blood-brain barrier [Laborit, 1964]. Further elucidation proved it an endogenous metabolite of GABA [Roth and Giarman, 1969] with a turnover of 0.16% of GABA being converted to GHB [Maitre, 1997] reference retrieved from https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3382678/

Sample Use Guides

Initiate dose at 4.5 grams (g) per night administered orally in two equal, divided doses: 2.25 g at bedtime and 2.25 g taken 2.5 to 4 hours later. Titrate to effect in increments of 1.5 g per night at weekly intervals (0.75 g at bedtime and 0.75 g taken 2.5 to 4 hours later). Recommended dose range: 6 g to 9 g per night orally.
