worry, anticipation of bad things, hyperattentive, difficulty concentrating, insomnia, on edge, impatience

4

what neurotransmitter is involved in slow wave sleep

A

serotonin

5

A

norepinephrine

6
Q

anxiety is treated with

A

benzodiazepines
SSRIs
buspirone

7
Q

insomnia is treated with

A

benzodiazepines
antihistamines
alcohol, cannabis, opiates

8
Q

benzodiazepine receptor is associated w which neurotransmitter?

A

GABA

9
Q

benzodiazepines bind to what receptor?

A

GABA A receptor

10
Q

where is GABA in the CNS

A
substantia nigra
globus pallidus
hippocampus
limbic-amygdala
hypothalamus
spinal cord (skeletal muscle relaxants)
11
Q

What is the action of GABA at the GABA A receptor?

A

it causes the chloride channel in the receptor to open

hyperpolarization

12
Q

how does benzodiazepine work

A

enhances action of GABA on GABA A receptor

13
Q

how are benzodiazepines and barbiturates similar?

A

both enhance actions of GABA on GABA A receptors

14
Q

cns actions of benzodiazepines

A
reduces anxiety (limbic)
sedation
hyponosis
muscle relaxation (sp cord)
anterograde amnesia
anticonvulsant (limbic)
MINIMAL CV and resp effects
15
Q

drug interactions for benzodiazepines

A

additive CNS depression along with ethanol, other hyponotics, sedating antihistamines

drugs impacting liver metabolism like cimetidine

16
Q

uses of benzodiazepines

A
anxiety
sleep disorder
muscle relaxant
seizure
IV sedation, anesthesia (still conscious but anterograde amnesia--wisdom teeth, put in tubes)
alcohol withdrawal
acute manic episodes
17
Q

benzodiazpine withdrawal

A
anxiety
insomnia
headache
hyperacusis
hallucinations
seizures
18
Q

treatment for abuse of benzodiazepines

A

gradual dose reduction–use longer acting drugs

19
Q

20
Q

what happens when you withdraw benzodiazepines when they are used for insomnia

A

rebound insomnia

21
Q

adverse effects of benzodiazepines

A
daytime drowsiness
ataxia 
rebound insomnia
tolerance and dependence
occasional excitement
22
Q

how does zolpidem compare to benzodiazepines for insomnia?

A

zolpidem does not change stage 3,4 sleep

23
Q

how do barbiturates compare with respect to benzodiazepines?

A

both act at GABA A receptor to enhance actions of GABA

barbiturates-more sedation
