drugs of abuse Flashcards
molec target of PCP, ketamine
NMDAR
ectasy long term use effects:
cognitive impairment
effect opoids
euphoria
long term effects LSD
flashbacks of altered perception yrs after consumption
withdrawal symp: n/v, m aches, lacrimation, rhinorrhea, mydriasis, piloerection, sweating, drh, yawning, fever
opioid withdrawal
efects: euphoria, relaxation, feelings of well-being, grandiosity, altered perception of passage of time, withdrawn, bloodshot eyes
cannabinoids
MOA amphetamines
-reversing action fo biogenic amine transporers at PM –> increased DA, SE, NE in synapse
effects: eupohria, enhanced sensory perceptions, feelings of social closeness, amnesia before sedation/coma
GHB
withdrawal: dysphoria, drowsiness (insomnia), irritability, depression
amphetamines
THC analogs used medically
dronabinol, nabilone
drugs to end addiction to nicotine
nicotine (gum, losenge, inhalers, transdermal applications), bupropion, varenicline
use of dronabinol
anorexia and wt loss in AIDS and chemo induced n/v
MOA GHB
- activities GABAb –> hyperpolarizes DA neurons and prevents DA release
- recreational doses: inhibit GABAb
MOA methadone, buprenophrine
long-acting opioids used for substiturino therapy
cociane binds to.. and MOA
DAT,=> increases DA conc in nuc accumbens
NET => blocks = activates sympathetics => HBP, tachy, ventricualr arrythmias, pupil dilation
SERT
what are the nonaddictive drugs of abuse?
LSD mescaline psilocybin PCP ketamine
common opoids used
morphine, heroin, coedine, oxycodone, meperidine
effects: loss appetite, hyperactivity, lack sleep, incrased risk intracranial hem, ischemic stroke, MI, seizures
cociane
Drugs that activate Gio-coupled receptors
opoids, cannabinoids, GHB
tx opoid withdrawal
naloxone, methadone, buprenophrine
effect of opoids, cannabinoids, GHB on DA neurons
disinhibition
ectasy binds to..
SERT > DAT, NET
withdrawal symp: mood offset: long depression and agression
ectasy
long term effects PCP
schizophrenia-like psychosis
withdrawal: restlessness, irritabilty, mild agiatation, insomnia, n, cramping
cannabinoids
overdose management inhalants
supportive care
drugs that mediate theri effects via ionotropic receptors
nicotine, benzodiazepines/barbituates, alch, inhalants
effect inhalants
eupohria
drugs that bind to transporters of biogenic amines
cocaine, amphetamines, ectasy
MOA varenicline
- partial nAchR agonist
- ->prevents nicotine stimulation of mesolimbic DA system assoc w nicotine addiction
MOA ectasy
-reversing action fo biogenic amine transporers at PM –> increased DA, SE, NE in synapse
MOA opoids
inhibs GABA –>disinhib DA
MOA naloxone
opoid antagonist
use of nabilone
refractory n/v assoc w CA chemo and adjunct to chronic pain managment
why we use bupropion
- antidepressant
- end nicotine addiciton
effect of LSD, mescaline, psilocybin, PCP, ketamine on DA?
none bc nonaddictive
SEs: psychedelic, HBP, impaired mem, disorientatino, nystagmus, visual alterations
PCP
ketamine
molec target LSD, mescaline, psilocybin
Gq
withdrawal: mild: irritabilty, sleeplessness
nicotine withdrawal
amphetamnes binds to..
DAT, SERT, NET, VMAT
cannabinoids MOA
- bind to presynap CB1 receptors and inhib release glutamate/GABA
- disinhibit DA
tx for cocaine overdose
supportive: control HR/R (propranolol), seizures (diazepam)
overdose: hyperthermia, coma, death
cociane
nicotine MOA
agonist nAchR –> DA release!
effects: hyperthermia, dehydration, serotonin synd (mental status change, autonomic hyperactivity, neuromusc abns), seizures
ectasy
