He received intravenous fluids and tapering dosages of lorazepam to control agitation and rigidity, and recovered with no significant sequelae after 8 days. Abrupt cessation of GHB after high-dosage abuse can precipitate a clinically significant withdrawal syndrome. Lorazepam should be considered for treatment of GHB withdrawal.

The most common form of ecstasy (3,4-methylenedioxymethamphetamine [MDMA]), is an amphetamine with some hallucinogenic properties at high doses. It is directly neurotoxic to the human brain and has been linked to a number of deaths worldwide. Deaths result from hyperthermia, hyponatremia, or cerebral edema. A naturally occurring metabolite of gamma-aminobutyric acid, gammahydroxybutyrate (GHB) is a potent central nervous system depressant. Although GHB is a Schedule I drug, analogs remain widely available for consumption. Acute intoxication with GHB or its analogs leads to coma and respiratory depression. Chronic use of GHB or its analogs is associated with a withdrawal syndrome characterized by autonomic excitation. Herbal ecstasy refers to ephedrine-containing preparations. Acute and chronic overdoses of herbal ecstasy have been linked to hypertension, tachydysrythmias, myocardial infarctions, cerebrovascular accidents, and deaths. There is no regulation of the ephedrine content of available herbal ecstasy products NT - UI - 21216458DA - 20010424IS - 1040-8703LA - engPT - Journal ArticlePT - ReviewPT - Review, TutorialCY - United StatesJC - BUTRN - 0 (Anesthetics)RN - 0 (Central Nervous System Stimulants)RN - 0 (Hallucinogens)RN - 299-42-3 (Ephedrine)RN - 42542-10-9 (N-Methyl-3,4-methylenedioxyamphetamine)RN - 502-85-2 (Sodium Oxybate)SB - IM UR - PM:11317061 SO - Curr Opin Pediatr 2001 Apr ;13(2):170-176 3 UI - 5 AU - Dupont P AU - Thornton J AD - Department of Medicine, Ashford Hospital NHS Trust, Middlesex, UK TI - Near-fatal gamma-butyrolactone intoxication--first report in the UK AB - Gamma-hydroxybutyrate (GHB) is a compound used in the treatment of alcohol withdrawal, narcolepsy, and for induction of anaesthesia. It is also contained in many products illegally marketed as "dietary supplements" and is increasingly being recognised as a potential drug of abuse. We report the case of a 44-year-old man who suffered coma and life-threatening respiratory depression following an accidental overdose of the GHB prodrug, gamma-butyrolactone (GBL), contained in a "health drink". He made a full recovery following appropriate supportive treatment. GHB toxicity should be included in the differential diagnosis of patients with altered mental state, particularly where there is a history of recreational drug abuse NT - UI - 21236210DA - 20010507IS - 0960-3271LA - engPT - Journal ArticleCY - EnglandJC - AQLRN - 0 (GABA Modulators)RN - 96-48-0 (4-Butyrolactone)SB - IM UR - PM:11339620 SO - Hum Exp Toxicol 2001 Jan ;20(1):19-22 4 UI - 9 AU - Dyer JE AU - Roth B AU - Hyma BA AD - California Poison Control System, San Francisco Division, San Francisco General Hospital, CA 94110, USA. jodyer@itsa.ucsf.edu TI - Gamma-hydroxybutyrate withdrawal syndrome AB - STUDY OBJECTIVE: Gamma-hydroxybutyrate (GHB) withdrawal syndrome is increasingly encountered in emergency departments among patients presenting for health care after discontinuing frequent GHB use. This report describes the characteristics, course, and symptoms of this syndrome. METHODS: A retrospective review of poison center records identified 7 consecutive cases in which patients reporting excessive GHB use were admitted for symptoms consistent with a sedative withdrawal syndrome. One additional case identified by a medical examiner was brought to our attention. These medical records were reviewed extracting demographic information, reason for presentation and use, concurrent drug use, toxicology screenings, and the onset and duration of clinical signs and symptoms. RESULTS: Eight patients had a prolonged withdrawal course after discontinuing chronic use of GHB. All patients in this series were psychotic and severely agitated, requiring physical restraint and sedation. Cardiovascular effects included mild tachycardia and hypertension. Neurologic effects of prolonged delirium with auditory and visual hallucinations became episodic as the syndrome waned. Diaphoresis, nausea, and vomiting occurred less frequently. The onset of withdrawal symptoms in these patients was rapid (1 to 6 hours after the last dose) and symptoms were prolonged (5 to 15 days). One death occurred on hospital day 13 as withdrawal symptoms were resolving. CONCLUSION: In our patients, severe GHB dependence followed frequent ingestion every 1 to 3 hours around-the-clock. The withdrawal syndrome was accompanied initially by symptoms of anxiety, insomnia, and tremor that developed soon after GHB discontinuation. These initial symptoms may progress to severe delirium with autonomic instability NT - UI - 21091525DA - 20010222IS - 0196-0644LA - engPT - Journal ArticleCY - United StatesJC - 4Z7RN - 502-85-2 (Sodium Oxybate)SB - AIMSB - IM UR - PM:11174231 SO - Ann Emerg Med 2001 Feb ;37(2):147-153 5 UI - 3 AU - McDaniel CH AU - Miotto KA AD - ULCA Department of Psychiatry and Biobehavioral Sciences, Los Angeles, California 90024, USA TI - Gamma hydroxybutyrate (GHB) and gamma butyrolactone (GBL) withdrawal: five case studies AB - There is little medical information available about gamma-hydroxybutyrate (GHB) or gamma-butyrolactone (GBL) dependence or withdrawal. In this study the authors treated and reviewed multiple cases of GHB and GBL withdrawal in high-dose users. Five patients during nine hospitalizations were treated for GHB or GBL withdrawal. The authors describe a spectrum of GHB or GBL withdrawal from mild to severe and discuss medications used for treatment. They conclude that patients with GHB or GBL withdrawal may present with agitated psychosis, delirium, and autonomic instability. In this sample, relapse to GHB or GBL use occurred soon after treatment of withdrawal NT - UI - 21368498DA - 20010730IS - 0279-1072LA - engID - Y01DA50038/DA/NIDAPT - Journal ArticleCY - United StatesJC - JLPSB - IM UR - PM:11476261 SO - J Psychoactive Drugs 2001 Apr ;33(2):143-149 6 UI - 2 AU - Miotto K AU - Darakjian J AU - Basch J AU - Murray S AU - Zogg J AU - Rawson R AD - UCLA Dept. of Psychiatry and Biobehavioral Sciences, 760 Westwood Plaza, Los Angeles, CA 90024, USA. kmiotto@mednet.ucla.edu TI - Gamma-hydroxybutyric acid: patterns of use, effects and withdrawal AB - Gamma-hydroxybutyric acid (GHB) is gaining popularity as a drug of abuse. Reports of toxicity and lethality associated with GHB use have increased. This survey study was designed to identify patterns of GHB use, its effects, and withdrawal syndrome. A survey inquiring about the effects of GHB was administered to 42 users. The results showed that GHB was used to increased feelings of euphoria, relaxation, and sexuality. Adverse effects occurred more frequently in daily users and polydrug users than in occasional GHB users. Loss of consciousness was reported by 66%, overdose by 28%, and amnesia by 13% of participants during GHB use and by 45% after GHB use. Three daily users developed a withdrawal syndrome that presented with anxiety, agitation, tremor, and delirium. Participants described GHB intoxication as having similarities to sedative-hypnotic or alcohol intoxication. Regular use has been shown to produce tolerance and dependence. Participants dependent on GHB reported using multiple daily doses around the clock. High frequency users appeared at the greatest risk for developing withdrawal delirium and psychosis after abrupt discontinuation of GHB use RP - NOT IN FILE NT - UI - 21464076DA - 20011002IS - 1055-0496LA - engID - DA9419/DA/NIDAPT - Journal ArticleCY - United StatesJC - CM2SB - IM UR - PM:11579621 SO - Am J Addict 2001 ;10(3):232-241 7 UI - 4 AU - Schneir AB AU - Ly BT AU - Clark RF AD - Division of Medical Toxicology, Department of Emergency Medicine, UCSD Medical Center, California Poison Control System-San Diego Division, 200 West Arbor Drive, San Diego, CA 92103-8925, USA TI - A case of withdrawal from the GHB precursors gamma-butyrolactone and 1,4-butanediol AB - We describe a case of withdrawal from the gamma hydroxybutyric acid (GHB) precursors gamma butyrolactone and 1,4-butanediol. Symptoms included visual hallucinations, tachycardia, tremor, nystagmus, and diaphoresis. Administration of benzodiazepines and phenobarbital successfully treated the withdrawal symptoms. As predicted from the metabolism of gamma butyrolactone and 1,4-butanediol to GHB, the symptoms were nearly identical to those reported from GHB withdrawal. Because GHB is now illegal in the United States, individuals have begun abusing the legal and easier to acquire GHB precursors. More frequent cases of both abuse and withdrawal from these GHB precursors can be expected NT - UI - 21293172DA - 20010611IS - 0736-4679LA - engPT - Journal ArticleCY - United StatesJC - IBORN - 0 (Anticonvulsants)RN - 439-14-5 (Diazepam)RN - 50-06-6 (Phenobarbital)RN - 846-49-1 (Lorazepam)RN - 96-48-0 (4-Butyrolactone)SB - IM UR - PM:11399385 SO - J Emerg Med 2001 Jul ;21(1):31-33 8 UI - 1 AU - Sivilotti ML AU - Burns MJ AU - Aaron CK AU - Greenberg MJ AD - Department of Emergency Medicine, University of Massachusetts Medical School, Worcester, MA, and the Division of Emergency Medicine, Harvard Medical School, Boston, MA TI - Pentobarbital for severe gamma-butyrolactone withdrawal AB - Study Objective: Gamma-hydroxybutyrate (GHB) and gamma-butyrolactone (GBL) have become popular drugs of abuse. Acute overdose with either agent results in a well-recognized syndrome of central nervous system and respiratory depression. Recently, a withdrawal syndrome has been described for GHB. We report a severe form of GBL withdrawal, characterized by delirium, psychosis, autonomic instability, and resistance to benzodiazepine therapy. METHODS: We performed a chart review of consecutive admissions for GBL withdrawal in a regional toxicology treatment center. RESULTS: During a 6-month period, 5 patients presented with severe withdrawal attributed to abrupt GBL discontinuation. Patients manifested tachycardia, hypertension, paranoid delusions, hallucinations, and rapid fluctuations in sensorium. Test results for ethanol and routine drugs of abuse were negative. Initial treatment with high doses of lorazepam proved ineffective. Pentobarbital was then administered, resulting in excellent control of behavioral, autonomic, and psychiatric symptoms and in rapid reduction or avoidance of benzodiazepines. Median hospital stay was 5 days. No patient had respiratory depression or required mechanical ventilation. Patients were discharged on tapering doses of benzodiazepines or pentobarbital and were free of psychotic symptoms at follow-up. CONCLUSION: GBL discontinuation can result in severe withdrawal, necessitating ICU admission. Pentobarbital may be more effective than benzodiazepines at controlling delirium in patients with abnormal vital signs, paranoid delusions, and hallucinations as a result of GBL withdrawal NT - UI - 21575520DA - 20011123IS - 0196-0644LA - engPT - Journal ArticleCY - United StatesJC - 4Z7SB - AIMSB - IM UR - PM:11719746 SO - Ann Emerg Med 2001 Dec ;38(6):660-665 9 UI - 15 AU - Craig K AU - Gomez HF AU - McManus JL AU - Bania TC AD - Department of Emergency Medicine of St. Luke's-Roosevelt Hospital, New York, New York, USA TI - Severe gamma-hydroxybutyrate withdrawal: a case report and literature review AB - We report a case of gamma-hydroxybutyrate (GHB) withdrawal resulting in severe agitation, mental status changes, elevated blood pressure, and tachycardia hours after stopping chronic use of GHB. The patient admitted to substantial GHB abuse on a daily basis for 2.5 years. Previous attempts at cessation reportedly resulted in diaphoresis, tremors, and agitation. The patient's symptoms, negative polypharmacy history, and negative urine and blood toxicological analysis for alcohol, benzodiazepines, sedative-hypnotics, or other substances suggested the diagnosis of GHB withdrawal. Later analysis of a patient drug sample confirmed the presence of GHB. The patient required 507 mg of lorazepam and 120 mg of diazepam over 90 h to control agitation. This is one of the few reported cases of GHB withdrawal and one of the most severe. Given the increasing use of GHB, more cases of severe GHB withdrawal should be anticipated NT - UI - 20108439DA - 20000207IS - 0736-4679LA - engPT - Journal ArticleCY - UNITED STATESJC - IBORN - 0 (Anti-Anxiety Agents, Benzodiazepine)RN - 0 (GABA Modulators)RN - 502-85-2 (Sodium Oxybate)RN - 846-49-1 (Lorazepam)SB - IM UR - PM:10645841 SO - J Emerg Med 2000 Jan ;18(1):65-70
