What are the implications of using GABA (Gamma-Aminobutyric Acid) hydroxybutyrate?

From the Guidelines

GABA hydroxybutyrate, specifically gamma-hydroxybutyrate (GHB), should only be used under strict medical supervision for approved conditions, such as narcolepsy, due to its potential for abuse and serious side effects, including respiratory depression and unconsciousness. The use of GHB is supported by recent clinical guidelines, including a 2021 study published in the Journal of Clinical Sleep Medicine, which recommends the use of sodium oxybate, the sodium salt of GHB, for the treatment of narcolepsy in adults 1. This study found that sodium oxybate was effective in improving excessive daytime sleepiness, cataplexy, and disease severity in patients with narcolepsy. However, the study also notes that GHB has a high potential for abuse and can cause serious side effects, including respiratory depression, unconsciousness, and coma.

Some key points to consider when using GHB include:

• GHB is a controlled substance with legitimate medical use as sodium oxybate for narcolepsy, but it carries serious risks, including respiratory depression and potential for abuse 1
• GHB has been used illegally as a "club drug" and in drug-facilitated sexual assault, and its use can lead to amnesia, intoxication, dizziness, and visual hallucinations 1
• The effects of GHB can last for 3 to 6 hours when taken without alcohol and 36 to 72 hours when mixed with alcohol or other drugs, and it is cleared quickly, making it difficult to detect in urine after only 12 hours 1
• Sodium oxybate, the sodium salt of GHB, is available through a risk evaluation mitigation strategy program using certified pharmacies, and its use should be closely monitored by a healthcare provider 1

In terms of safety, the use of GHB should be approached with caution, and patients should be closely monitored for signs of abuse or adverse effects. The potential benefits of GHB for approved conditions, such as narcolepsy, should be weighed against the potential risks, and alternative treatments should be considered when possible. Additionally, patients should be educated about the potential risks and benefits of GHB and the importance of using it only under strict medical supervision.

From the Research

Implications of Using GABA Hydroxybutyrate

The implications of using GABA (Gamma-Aminobutyric Acid) hydroxybutyrate, also known as gamma-hydroxybutyric acid (GHB), are multifaceted and can be understood through its effects on the brain and body.

• GHB is a catabolite of GABA in the brain and is also found in non-neuronal tissues 2.
• Administration of large doses of GHB leads to sedation and, at high doses, anesthesia, suggesting its potential as an anaesthetic adjuvant 2.
• GHB has been used to treat alcoholic patients by attenuating the withdrawal syndrome, possibly by acting as a pro-drug of the neurotransmitter GABA 2.
• The use of GHB may have implications for the treatment of epilepsy, as it can induce electroencephalographic and behavioral changes resembling those of human petit mal epilepsy 2.
• GHB may also play a neuroprotective role by lowering cerebral energy requirements 2.

Physiological Significance and Role in Disorders

The physiological significance of GHB and its role in various disorders are areas of ongoing research.

• GHB is a metabolite of GABA and has been discussed in terms of its physiological significance and its role in epilepsy, sleep disorders, drug and alcohol addiction, and an inborn error of GABA metabolism 3.
• The GABAergic system, which includes GHB, is targeted in the treatment of anxiety disorders, epilepsy, and other conditions 4, 5, 6.
• Phytomedicines that modulate GABA pathways, including those that interact with GHB, may provide novel treatment options for anxiety disorders 5.

Pharmacological Potential and Pitfalls

The pharmacological potential and pitfalls of GHB and related compounds are important considerations.

• GABA receptors, including those targeted by GHB, are involved in the regulation of neuronal transmission and are targeted by many clinically important drugs 6.
• The development of subtype-selective drugs that target GABA receptors, including those that interact with GHB, may lead to more effective therapeutic strategies with fewer side effects 6.
