tolerance (class) Flashcards
(44 cards)
Feeling of “high” doesn’t “feel as good”
illicit drug tolerance def
does not alleviate symptoms
medical drug tolerance def
Desensitation to drug effects”
tolerance
tolerance can result from? (3)
- repeated exposure that affects physiology (dosage, rates–> time)
- developmental/physiological changes that alter chemical reactions
- psychological state (expectancy, boredom)
tolerance is dependent on? (2)
- drug type (toxicity, accrued or eliminated)
- body (selective tolerance)
one effect is diminished, but another is not
selective tolerance
drinking a coke right before bed and falling asleep right away but then needing a coffee every morning to wake up is an example of?
selective tolerance
Used synonymously with potential treatment
tolerance
what else can change the tolerance level of a dug? (3)
- psychological state (might just feel higher cause your bored)
- behaviour (what you are doing)
- environment (taking it at home vs taking it at the club)
Physiological response (i.e. CNS; enzymes, receptors) --> what type of tolerance
functional tolerance
what type of tolerance are ppl used to seeing
functional tolerance
- Occurs after several exposures – Cellular adaptation similar to acute, except over time/repeated exposure
- > what type of tolerance
functional tolerance
Requires more drug to obtain similar subjective effect (graded)
functional tolerance
taking more drugs to avoid withdrawal symptoms is a characteristic of what?
functional tolerance
occurs after only one exposure
acute functional tolerance
Physiological efficiency; cells lose sensitivity to a drug • May have to do with toxicity of drug/metabolite, and similarity to endemic compounds
acute functional tolerance
Reduces the subjective effect (threshold) – including in cross-tolerance
acute functional tolerance
what is cross tolerance?
there is sugar in alcohol so and if your used to eating lots of sugar your body may respond the same based on similarity (eat lots of sugar, build ore tolerance to alcohol)
during acute functional tolerance, psychological effects are observable during? and not?
- increase, not elimination
what is the cell adaption theory based off of?
homeostasis
Body attempts to obtain a state in which energy/resources are used most efficiently, with the least “loss” (balance)
homeostasis
homeostasis is regulated by?
receptors and neurotransmitters
upregulation?
down regulation?
- increase sensitivity to a drug
- avoid toxicity (activiation cause by drug)
what changes in upregulation/down regulation
the number of receptors or the number of NT, NOT the sensitivity of receptors
(always an opposite rxn b/w NT and receptors)
