Abstract
Introduction: Gamma-hydroxybutyric acid (GHB) is commonly known as a recreation drug or the so-called “date rape drug”. It is also used in medicine to treat narcolepsy and alcohol addiction. GHB has an affinity for two types of receptors: GABAB and the relatively recently discovered GHB receptors. GHB receptors were first cloned in 2003 in mice and then in 2007 in humans. So far, evidence has been presented for their impact on dopaminergic transmission, which may imply that they play a role in the pathogenesis of diseases such as schizophrenia. At the same time, it has been demonstrated that benzamide antipsychotic drugs have an affinity for GHB receptors, which is why it is postulated that some of the effects of these drugs may result precisely from this affinity.
Aim: The study presents the current state of knowledge about GHB receptors and their potential role in the pathogenesis of schizophrenia, and discusses drugs which show an affinity for this receptor.
Material and method: The literature review was based on a search of articles indexed between 1965 and 2018 in Medline, Google Scholar, ScienceDirect and Research Gate databases. The following search terms were used: GHB receptor, GHB, sulpiride, and amisulpride.
Result and discussion: 1. It is possible that GHB receptors are involved in the pathogenesis of schizophrenia, although more research is needed in this area. 2. Part of the effects of some benzamide antipsychotic drugs (such as amisulpride) may be due to their affinity for GHB receptors.
