gamma-Hydroxybutyric acid




γ-Hydroxybutyric acid (GHB), also known as 4-hydroxybutanoic acid, is a naturally occurring neurotransmitter and a psychoactive drug. Chemically closely related to GABA, it acts on the GABA receptor and on the GHB receptor.
GHB has been used in a medical setting as a general anesthetic, for cataplexy, narcolepsy, and alcoholism. It is also used illegally as an intoxicant, to try to increase athletic performance, and as a date rape drug. It is commonly used in the form of a salt, such as sodium γ-hydroxybutyrate (Na.GHB, sodium oxybate, or Xyrem) or potassium γ-hydroxybutyrate (K.GHB, potassium oxybate).
