NUR 2407 Drug actions and definitions
1. define agonist
Answer
activates a receptor. produces a desired response
2. define antagonist
Answer
blocks a receptor and prevents a response.
3. Benzodiazepines
Answer
Antianxiety - enhances the inhibitory effects of GABA in the central nervous system.
4. Anticholinergic actions
Answer
Sympathetic response, supresses acetylcholine, (bron- chodialor, reduces secretions, increases
heart rate, vasoconstrction)
5. Cholinergic actions
Answer
Parasympatheletic response, mimics acetylcholine (Di- alates blood vessels, contracts smooths
muscles, lowers heart rate, and increases secreations)
, 6. SSRIs (selective serotonin reuptake Inhibitors)
Answer
Antidepressant - inhibits sero- tonin reuptake, increase serotonin between neuron junctions
7. SNRIs (seroronin-norepinephrine reuptake inhibitor)
Answer
Antidepressant - blocks norepinephrine and seroronin reuptake between neuron junctions
8. tricyclic antidepressants
Answer
block reuptake of serotonin and norepinephrine in the synaptic space, increasing the effect of
these neurotransmitters
9. MAOIs (monoamine oxidase inhibitors)
Answer
Increases the amount of norepineph- rine, dopamine, serotonin, and tyramine in the brain
intensifing neurotransmitter response.
10. Lithium Carbonate
Answer
Mood Stabilizer (for Bipolar clients) - produces neurochem- ical changes, blocking serotonin
receptor
11. mood-stabilizing antiepileptic drugs (AEDs)
