Ecstasy: The drug of a new generation. Ecstasy = MDMA 3,4 methylenedioxymethamphetamine X, E, M, XTC, Rolls, Adam, Bean, Hug Drug MDMA History 1912 – first synthesized by Merck 1914 – patented by Merck – manufactured as an appetite suppressant, never marketed 1950’s- studied by US Army as potential agent in psychological warfare 1970 – used in psychotherapy, “penicillin for the soul” 1977 – class A illegal drug in UK 1985 – Schedule I illegal drug in U.S. Areas of Usage Highest at raves, dance clubs (as high as 91% of clubbers in dance scene in Scotland) Dramatic increase in college use, suburban teens, house parties Millroy, CM, JRSM February 1999 Physical CLUES Glowsticks or lights Lollipops Pacifiers Vick’s Vapor Rub and Nasal Inhaler Fuzzy Mittens Most Predictive Factor of Drug Use = CLUB MUSIC! Methods of Administration Mainly PO – stamped tablets, capsules Intra-nasal – rapid absorption of crushed tablets or opened capsules Intra-rectal – faster absorption than PO Recreational usage varies from ½ pill to as much 15 pills in a 6 hour span MDMA Adulterants MDEA MBDB MDA PMA Caffeine Dextromorphan Aspirin Piracetam Methamphetamine PCP Ketamine Heroin Quinine LSD Marijuana Ephedrine MDMA Onset 20-90 min Rise up 5-20 min Plateau 2-3 hours Come 1-2 down hours After 3-24 Effects hrs Positive Effects Extreme euphoria Increased energy Feelings of belonging and closeness Heightened sensations (touch, taste, smell, hearing) Increased openness Feelings of love and empathy Bright, intense visual perceptions Musical appreciation Fear dissolution “Profound” thought Other Effects Appetite loss Vertical nystagmus (rolling) Moderate increases in HR and BP Mild visual hallucinations Mind racing Changes in thermoregulation Restlessness, nervousness, shivering Strong desire to take more drug during come down Mydriasis Negative Side Effects Mild to extreme trisma and bruxism Short-memory loss Confusion Vertigo, ataxia Muscle tension Nausea & vomiting Concentration difficulties “Crash” come down Hangover lasting days to weeks Depression and fatigue for up to a week Psychological addiction Panic attacks Major Toxic Complications Hyperthermia/Heat Stroke Dehydration Hyponatremia SIADH Hepatitis/Liver Failure Rhabdomyolysis/Renal Failure Neurotoxic Effects Acute Psychotic Break/Severe Depression Death! Ecstasy Related Fatalities 87 cases reported in the literature caused by: Hyperpyrexia – 30 Hepatic – 4 Cardiovascular/Cerebrovascular – 8 Cerebral, including Hyponatremia – 9 Drug Related Accidents or Suicide – 14 Unknown – 22 Kalant, H; Canadian Medical Association Journal, October, 2001 Major Physical Toxicity Hepatic Mild viral hepatitis – jaundice, enlarged tender liver, elevated LFT’s/Coags – self limited, 2 wks-3 mo, related to glutathione decrease and oxidative cell destruction Prolonged hepatitis – slow recovery with potential permanent fibrosis Fulminant liver failure – fatal without liver transplant Kalant, H; Canadian Medical Association Journal, October, 2001 Major Physical Toxicity Cardiovascular NE responsible: HTN and tachycardia Major intracranial hemorrhage Petechial hemorrhages – brain and other organs Retinal hemorrhage at autopsy Intravascular thrombosis and CVA Serious cardiac dysrhythmias Pulmonary edema/heart failure Major Physical ToxicityCerebral Hyponatremia- result of vigorous physical activity, profuse sweating, large Na+ loss, excessive water consumption SIADH – less common mechanism of water retention, but can complicate picture Cerebral edema w/hyponatremic seizures – therapy includes BZD’s and cautious replacement of Na with hypertonic saline Brain stem and cerebellum compression Hyperpyrexic Pattern of Toxicity Most dangerous form of ecstasy induced toxicity Results from a combo of drug action, intense physical activity, and hot environment Adulterants such as dextromorphan can inhibit sweating leading to further heat retention Changes resemble those seen in severe heatstroke Features of Hyperpyrexia Rhabdomyolysis – heat production and muscle necrosis Myoglobinuria and renal failure – secondary to rhabdomyolysis Hepatic necrosis DIC PMA Paramethoxyamphetamine Pills contain 50mg of PMA, look like MDMA tablets Longer duration to onset – toxic in doses of 60-80mg Rapid rise in BP and temp leading to convulsions, coma, and death Responsible for 10 deaths (3 in suburbs of Chicago) Gamma Hydroxybutyrate Acid (GHB) Liquid ecstacy Liquid G Gamma Oh Grievous bodily harm Scoop Samatomax Bioski Cow Growth Hormone Georgia Home Boy GHB Analogue of inhibitory neurotransmitter gamma-aminobutyirc acid- CNS depressant Synthesized in 1960 and used in 1970’s for sleep disorders because it induces REM sleep Used in Europe as anesthetic agent until found that it caused seizures 1977, study claimed it stimulated effects of Growth Hormone GHB Unapproved drug in US, but legally obtainable under FDA investigational New Drug exemption for treatment of narcolepsy –20 states have controlled its use with penalties similar to marijuana possession Gamma Hydroxybutyrate Acid (GHB) Readily available in drug market and inexpensive and relatively easy to make – recipes are obtainable on the internet Obtainable as clear and odorless liquid, gel, or powder which have a salty taste – however, taste is masked by ETOH which increases its clinical effects GHB Used in date rape because: –quick onset of effect – easily obtainable – small quantities are needed –causes hallucinations and amnesia making the patient an unreliable witness GHB GHB - Toxicity Acts as neurotransmitter affecting GHB and GABA- B receptors causing CNS depression – takes effects in 15-30 minutes causing drowsiness, dizziness, and disorientation – duration of action up to 3 hours – half life of 20 min to 1 hour – hallmark is marked agitation upon stimulation despite apnea and hypoxia 10mg/kg causes vomiting, rapid onset of coma and amnesia 20-30mg/kg cause rapid cycles of REM and non-REM sleep 50mg/kg can cause resp depression, bradycardia, clonic muscle contractions, and decreased cardiac output GHB - Other forms Gamma butyrolactone (GBL) - can be purchased from chemical supply stores or catalogues and converted to GHB with NaOH – GBL is rapidly converted to GHB by peripheral lactonases within minutes 1,4-Butanediol - can be purchased in similar manner as GBL –converted to gamma hydroxybutyaldehyde by alcohol dehydrogenase –then, converted to GHB by aldehyde dehydrogenase Ketamine Ketamine AKA: Special K, Super Acid, Super C used as an anesthetic in EM and veterinary medicine Ketamine is a controlled substance in 18 states as schedule III drug Used in date rape because: – rapid onset – dissociative hallucinogenic Ketamine - Toxicity Chemically related to PCP takes effect 15-20 minutes, producing analgesia Higher doses produces dissociative hallucinations, delirium, resp depresion, Sz, arrythmias and cardiac arrest Effects last 20-45min Ketamine - Treatment Mainly supportive No antidote Pt should be placed in quiet room with minimal stimulation http://www.google.com/url?sa=t&rct= j&q=&esrc=s&source=web&cd=1&ved =0CCAQFjAA&url=http%3A%2F%2Fw ww.uic.edu%2Fdepts%2Fmcpt%2Fcur riculum%2Fcpp%2Fppt%2FEricksonDrugsHandout.ppt&ei=WlFYVJztD4uGi gLd14GYAQ&usg=AFQjCNGsK-ZHSCeSoYtGnhC2Knwtg7XIg&sig2=GnpLCm MWlkRJYEpsnfgSbw&bvm=bv.786774 74,d.cGE
