Q

so what happens if you withdrawal benzos quickly?

A

the increased glutamate and receptors will lead to stimulation and you get anxiety/panic, insomnia, tachycardia

Q

how do benzos cause dopamine release in the nucleus accumbens?

A

they inhibit the release of GABA so more excitation in the area with loss of GABA

Q

what are long term results of alcohol withdrawal?

A

seizures 2-5 days out

delirium tremen 3-7 days out

17
Q

what is the reversal agent for benzodiazepines?

18
Q

what is the MoA of Flumazenil?

A

competitively inhibits the binding of benzos to GABA receptors

19
Q

what two drugs are benzos synergistic with that can lead to death?

A

alcohol and opiates

20
Q

what is the issue with benzo metabolism?

A

can lead to sedation through active metabolites

21
Q

which two benzos have significant active metabolites in breakdown?

A

chlordiazepoxide and diazepam

22
Q

which three benzos do not have any metabolites in breakdown? what does this mean about them?

A

Lorazepam
Oxazepam
Temazepam
means they have no sedation side effect

23
Q

what GABA receptor do benzos bind to be anxiolytics?

24
Q

what GABA receptor do benzo metabolites bind to be sedative?

25
what is the MoA of Buspirone?
agonizes the inhibitory serotonin autoreceptor and decreases pre synaptic serotonin release
26
what are SEs of buspirone?
not really any
27
how do SSRI and SNRIs treat anxiety?
treat underlying depression
28
what class of drugs stimulates the a1 GABA-R receptor?
Z drugs
29
name the Z drugs
Zalepon Zolpidem Eszopiclone
30
what is the MoA and effect of Zalepon, Zolpidem and Eszopiclone?
they bind the a1-GABA receptor and induce sedation
31
what can Zalepon, Zolpidema and Eszopiclone cause?
sleep walking/eating/driving
32
what is the drug to give for inducing sleep that is similar to melatonin?
Ramelteon
33
when do you give ramelteon?
at night when sun goes down
