Description
(extracted from source data)
INDICATION For the treatment of cataplexy and excessive daytime sleepiness (EDS) associated with narcolepsy.
ROE Animal studies indicate that metabolism is the major elimination pathway for sodium oxybate, producing carbon dioxide and water via the tricarboxylic acid (Krebs) cycle and secondarily by beta-oxidation. Succinic acid enters the Krebs cycle where it is metabolized to carbon dioxide and water. Fecal and renal excretion is negligible.; 5% renal elimination.
TOXICITY High doses of GHB may lead to nausea, dizziness, drowsiness, agitation, visual disturbances, depressed breathing, amnesia, unconsciousness, and death in some cases.
DESCRIPTION γ-hydroxybutyrate (GHB) is a metabolite of . (GtoPdb)
PHARMACODYNAMICS GHB predominantly works at two distinct binding sites in the central nervous system: it works as an agonist at the newly-characterized excitatory GHB receptor, while acting as a weak agonist at the inhibitory GABAB receptor. Since it is a naturally occurring substance, its physiological action is similar to that of some endogenous neurotransmitters in mammalian brain. GHB is probably synthesized from GABA in GABAergic neurons, and released when the neurons fire.
MOA GHB is present at much higher concentrations in the brain, where it activates GABA-B receptors to exert its sedative effects. With high affinity, GHB binds to excitatory GHB receptors that are densely expressed throughout the brain, including the cotex and hippocampus. There is some evidence in research that upon activation of GHB receptors in some brain areas, the excitatory neurotransmitter glutamate is released. GHB stimulates dopamin release at low concentrations by acting on the GHB receptor, and the release of dopamine occurs in a biphasic manner. At higher concentrations, GHB inhibits dopamine release by acting on the GABA-B receptors, which is followed by GHB receptor signaling and increased release of dopamine. This explains the paradoxical mix of sedative and stimulatory properties of GHB, as well as the so-called "rebound" effect, experienced by individuals using GHB as a sleeping agent, wherein they awake suddenly after several hours of GHB-induced deep sleep. It is proposed that overtime, the level of GHB in the brain decreases below the threshold for significant GABA-B receptor activation, leading to preferential activation of GHB receptor over GABA-B receptors and enhanced wakefulness.
