The drug follows non-linear pharmacokinetics. As it has been associated with misuse/abuse it is strictly controlled and all patients and prescribers must enroll in the sodium oxybate REMs program in order to gain access to the medication.
Sodium oxybate (Xyrem) is a central nervous system depressant used for the treatment of cataplexy and extreme daytime sleepiness (EDS) associated with narcolepsy. It is the sodium salt of gamma hydroxybutyric acid (GHB) which is an endogenous compound and a metabolite of the neurotransmitter GABA. The exact mechanism of action for treating EDS and cataplexy is not known but is is hypothesised that its therapeutic effects are due to GABA(B) effects on noradrenergic, dopaminaergic and thalamocorticol neurons.
SODIUM OXYBATE (SOE dee um OX i bate) is used to treat excessive sleepiness and cataplexy in patients with narcolepsy. Cataplexy causes a sudden muscle weakness due to a strong emotional response.
This medicine may be used for other purposes; ask your healthcare provider or pharmacist if you have question kindly get back to us for more details.
For the treatment of cataplexy in narcolepsy and excessive daytime sleepiness (EDS) in narcolepsy.
Sodium oxybate works through an unknown mechanism to treat narcolepsy by inducing sleep within about 5-15 minutes of administration.
The exact mechanism of action is unknown. It is the sodium salt of the endogenous compound gamma hydroxybutyrate which is a metabolite of the GABA neurotransmitter and it’s thought that it’s therapeutic effects are mediated via GABA B actions at noradrenergic, dopaminergic and thalamocortical neurons.
