Q

SYNTHETIC RECEPTOR ANTAGONIST: rimonabant (Acomplia)

A
  • blocks CB1 receptors and acts as an inverse agonist to facilitate effects opposite of cannabinoid agonists
  • appetite suppressnat and anti obesity

Q

recreational synthaocannabinoids- herbal incense

A

compounds sold as synthetic marijuana to be smoked for recreational use
dont contain cannabis plant material
uneven distribution making dosages unpredictable

Q

absorption

A

oral- low bioavailbility due to lipid solubility and water insolubility, increased when added oil/fat
inhalation- rapidly absorped into respiratory tract
but do lose product through smoke
spray - pharmaceutical use, slower absorption and bioavailability

Q

distribution

A

quickly removed from body
depends on rate of blood flow
long term storage in body fat - not in brain

Q

elminiation

A

some metabolism in lungs, some in intestines
most occurs in liver - CYC p450 enzymes
metabolite: 11-OH-THC
once broken down they are attached to O-esterglucoronide
can last 4 days to a few weeks

13
Q

neuropharmacology of THC

A

high affinity selective cannabinoid receptor in brain tissue - CB1& CB2
G protein coupled receptors that inhibits adenylyl cyclase reducing cAMP and PKA also inhibits Ca channels leading to hyperpolarization and inhibit transmitter release

Q

cannabinoid receptors in body

A

CB1- primarily responsible for CNS on presynaptic terminals
mediate the psychoactive effects of THC (euphoria)
CB2- primarily in PNS, play a role in immune system

Q

synthesizing endocannabinoids

A

not packaged in vesicles , made on demand
functions as a modulator of other NTs
increase firing of dopamine neurons in striatum (by inhibiting GABA)

16
Q

effects on body

A

bloodshot eyes- dilation of blood vessels, dry mouth, hunger, increase HR, muscle relaxation

17
Q

effects on sleep

A

causes fatigue and dowsiness at low doses

can cause restlessness and insomnia in high doses

18
Q

effects on perception

A

disrupt sensory function - can intensify or distort visual or auditory
mild synesthesia
temporal disintegration- altering of thinking processes

19
Q

creativity

A

enhanced creativity may be explained by blood flow to the right hemisphere of the brain

20
Q

aggression

A

those given low doses responded most aggressively comapred to those given high doses

21
Q

memory

A

high density of Cb1 receptors in hippcampus
affects verbal and episodic short term emmory
disruption of ability to recall words
tolerance to this in heavy users
shows greater activity in the area to achieve baseline

22
Q

driving

A

negatively impacts coordination, sensory, motoor and therefor driving
direct attention toward themselves and fail to attend to task

23
Q

titration

A

users titrate dose by altering smoking behavior

24
Q

THC as an antiemetic

A

drug that stops nausea and vomitting

25
Q

cachexia

A

wasting and malnutrition that occurs in AIDS

26
Q

cannabis on diseases

A

glaucoma, parkinsons, tourettes, huntingtons, crohns, sleep disorders

27
Q

harmful effects

A
  • no receptors in brainstem so no effect on breathing/overdose
  • synthocannabinoid can cause seizures, heart attack, paranoia, anxiety
  • can induce mental disturbance/psychosis (CBD may counteract)
28
Q

what has an effect on developing scizophrenia

A

age of exposure
endocanabanoids regulate synaptic pruning during adolescence
may potentiate an underlying genetic predisposition

29
Q

which study is best to examine marijuana use and IQ

A

longitudinal- allows time progression (but correlational)

- found intelligence was imparied when introduced to cannabis in adolescence and continued use

30
Q

amotivational syndrome

A

change in life style, ambitions, motivation and personality

  • unable to expereince pleasure
  • negatively impacts attention and memory
31
Q

common factor model

A

individuals have a random propensity to drugs correlated with risk of oppurtunity and probability that isnt related to hard drug use

32
Q

tolerance

A

pharmacodybanuc - develop rapidly and diminish rapidly

33
Q

withdrawal

A

mainly psychological
more sever in synthaocannabinoids due to high affinity of CB1 agonist over partial agonist (THC)
antipsychotics may eleviate
