Gamma hydroxybutyric acid (GHB) is a GABA analog popular as a supplement and recreational drug. Overdose can cause severe respiratory depression and death, but most patients recover with prompt medical care.

Area of Science:

  • Neuroscience
  • Toxicology
  • Emergency Medicine

Background:

  • Gamma hydroxybutyric acid (GHB) is a naturally occurring GABA analog with historical research and clinical applications.
  • GHB has gained popularity as a dietary supplement and recreational drug in the last decade.
  • Congeners like gamma butyrolactone (GBL) and 1,4-butanediol (1,4-BDO) are emerging as substances of abuse with similar effects.

Purpose of the Study:

  • To inform emergency physicians about the presentation and management of GHB-related emergencies.
  • To highlight the risks associated with GHB overdose and withdrawal.
  • To raise awareness of GHB congeners and their similar toxicological profiles.

Main Methods:

  • Review of clinical presentations of GHB intoxication.

Related Experiment Videos

  • Analysis of outcomes in patients with GHB overdose.
  • Comparison of GHB and its congeners' toxicological effects.

    • Main Results:

    • Acute GHB overdose can lead to altered mental status and respiratory depression, with severe cases resulting in respiratory arrest and fatalities.
    • Most patients experiencing GHB overdose recover within six hours with appropriate medical management.
    • A GHB withdrawal syndrome, similar to sedative/hypnotic and ethanol withdrawal, has been identified.

    Conclusions:

    • Emergency physicians must be prepared to manage GHB-related emergencies, including overdose and withdrawal.
    • Understanding the toxidromes of GHB and its congeners is crucial for effective treatment.
    • Prompt recognition and management are key to favorable outcomes in GHB intoxication.
