2. ADHD Rise in prescribing psychoactive meds for ADHD
Use of prescription stimulants and diagnosis of ADHD higher in US than any other nation
We consume majority of worlds ritalin
Increased awareness of ADHD
Increased treatment duration meaning more people bringing to college
3. ADHD First line therapy stimulants
Methylphenidate
ritalin
Amphetamine-dextroamphetamine
Adderall
4. Abuse of Adderall and Ritalin With increased prescription rates of adderall and ritalin abuse also rising
Non-medical use of prescription subtances in college second only to MJ in illicit use
EtOH abuse staying steady
5. Prevalance of Abuse: Study 1 Survey of over 10,000 college students randomly selected
Lifetime prevalence of 6.9%
Past year prevalence 4.1%
Past month prevalence 2.1%
Use highest in white male members of fraternities with lower GPA’s
Highest use in north eastern colleges and colleges with high academic requirements
More likely to abuse other drugs--Binge drinking, MJ, ecstasy, cocaine
6. Pevalence of Abuse: Study 2 Self-administered web based survey of randomly selected college students N=4580
Lifetime-8.3%
Past year-5.9%
3/4 of the past year use with adderall
1/4 of past year with ritalin
Caucasians and Hispanics 3X more likely to use than African-Americans and 2X more likely than Asians
7. Motives Better grades
8. Motives Increase concentration
“Help Study”
Increase alertness
Get high
Experimentation
Lose weight (women)
9. Routes of Administration Oral use 95%
38% snorting
5% smoke
Very few inject
10. Clinical Manifestations of Amphetamine overdose Increase peripheral and central catecholamine concentrations
Tachycardia, HTN, AMI, seizures, intracranial bleeds, CVA
Hyperthermia, rhabdo
Mydriasis
Agitation
Acute psychosis
Death
11. Amphetamine OverdoseTreatment ABC’s
Monitor and treat arrhythmias
Gastric lavage if oral ingestion and recent use (approximately 1 hour)
IV drips for vasodilatation-nifedipine, nitroprusside; alpha blockade-phentolamine; alpha-beta antagonists-labetalol)
Hold BB
IV fluids if signs of rhabdo
Cool down patient (more on this later)
Counseling
12. Designer Drugs Synthetic derivatives of controlled substances made by altering molecular structure
Mid 80’s legislation made illegal to due this
Some of most popular amphetamine derivatives
13. Amphetamine Analogs Made by attaching different substituent groups to different positions on the phenyl ring of amphetamine or methamphetamine
Substituents-methoxy, methyl, halogen, sulfur
14. MethylenedioxymethamphetamineMDMA Ecstasy, E, X-TC, Adam, Clarity, Stacy, Lover’s Speed, Essence
First made in 1914 for appetite suppressant, later use in 1970’s by psychotherapists and now a schedule I drug
Most made in Europe and smuggled to US
Stimulant and psychedlic effects
Effects by serotonin and small degree Dopamine
15. Forms of MDMA Capsule or tablet
Powder snorted or smoked
One tablet-$10-30$ or more
Can find descriptions of synthesis in scientific journals and internet but still hard to make
Improper synthesis responsible of the many impurities found in MDMA
16. Mechanism of Action On neurons that make and release serotonin
MDMA-causes release of serotonin into synaptic cleft, inhibits its breakdown, and does not allow reuptake
Therefore increased concentration in cleft and intracellular depletion of serotonin
Effects begin 1 hour after ingestion and last 3-6 hours
Chronic use-paranoid psychosis similar to schizophrenia and can go away after prolonged drug free state
Chronic use-can lead to cognitive decline
17. Other Amphetamine Analogs Methamphetamine
Speed, crank, meth, crystal meth
Schedule II drug
Contaminants-lead (acute lead poisoning)
Methylenedioxyamphetamine
Methylenedioxyethamphetamine
Paramethoxyamphetamine
18. Clinical Manifestations Increased energy and ability to concentrate, euphoria, relaxation, empathy, paranoia
Impulsive with increased risk taking
Suppress thirst and hunger-dehydration and heat exhaustion
Tachycardia, HTN, hyperthermia, tremors, pupillary dilation
MDMA-raised HR 28BPM, DBP 7mmHg, cardiac output by 2L/Min
19. Treatment As amphetamine overdose
20. Treatment-Drug Induced Hyperthermia Life threatening and similar to heat stroke
Discussion with toxicologist recommended
Active cooling measures--iced IVF, cool water bladder washes, cooling blanket
Hypotension-IVF and pressors
Dantrolene has been used but no controlled trials
Intubation and paralyzation to decrease muscle contractions and rigidity
Careful with succinylcholine as can cause malignant hyperthermia making problem worse
Normalize intracranial pressures
DIC
Metabolic acidosis and hypocalcemia
