31
depending on tolerance, people can go into severe withdrawal early than ____
48hrs
32
if a patient has stopped alcohol 50 hours ago and has not had a seizure, is it likely that they will have one?
no- if >48hrs
33
T or F: alcohol withdrawal is fatal
T
34
how dose alcohol withdrawal result in seizures
With chronic alcohol use, brain and body adapts so GABA mediated systems becomes less sensitive and GLU systems become hypersensitive- sudden stop = increased sensitivity to excitation (hypersensitive glutamate system) = lowers seizure threshold
35
list 3 factors that increase withdrawal
seizure withdrawal, previous tremens, + hx for impatient residential tx programs, blacked out, use of other CNS depressants or illicit substances, evidence of increased autonomic activity (if HPTN + HR already high)
36
T or F: delirium tremens can be fatal
T
37
what are some lab liver function test findings with alcohol use disorder
increased GGT + increased AST, ALT, bilirubin
38
lab findings of complete blood count in AUD
increased MCV, macrocytic anemia lowered folate and thiamine
39
electrolyte changes in AUD
disturbances in phosphate, potassium, magnesium
40
changes in blood glucose with AUD
decreased BG ketoacidosis possible
41
which tool helps identify pts who may be msot at risk for developing severe alcohol withdrawal sx
PAWSS
42
waht is a tool used to assess level of withdrawal
CIWA-Ar
43
list 4 complications from alcohol withdrawal
seizures, delerium tremens, Wernicke's encephalopathy, korsakoff's dementia
44
what is Wernicke's encephalopathy
complication from alcohol withdrawal secondary to severe thiamine deficiency
45
what causes wernicke's encephalopathy
decreased food consumption and absorption + storage in liver = less thiamine
46
sx of wernicke's encephalopathy
CNS depression, wide ataxic gait, pupil abnormality, nystagmus, hemorrhage, decreased BP and temp
47
sx of korsakoff's dementia
persistent psychosis, confabulation, retrograde and anterograde amnesia
48
T or F: most people with korsakoff's dementia do not recover
T
49
tx for korsakoff's dementia
prevention is essential as most do not recover AP, cholinesterase inhibitors, thiamine replacement
50
how to prevent Wernicke's encephalopathy
thiamine vit B1, then give glucose
51
describe the pathology of Wernicke's
alcohol metabolism increases demand for thiamine, but poor nutrition decreases supply = decreased coenzyme thiamine pyrophosphate required for glucose metabolism in the brain = no glucose available for brain = WK encephalopathy
52
1st line for alcohol withdrawal tx
benzodiazepines
53
3 most common BZDs used for alcohol withdrawal tx
lorazepam, diazepam, chlordiazepoxide
54
what type of BZDs are preferred for alcohol withdrawal
longer acting agents for seizure prevention and less breakthrough sx
55
there is an increased risk of addiction with the 3 following BZDs due to their fast onset
diazepam, alprazolam, lorazepam
56
BZDs in alcohol withdrawal should be dosed ___
PRN by sx
57
which BZD is preferred in elderly
lorazepam
58
lorazepam is the preferred BZD in
elderly, those with respiratory depression, hepatic disease
59
why is lorazepam the preferred BZD in elderly, resp dep, and hepatic disease
no active secondary metabolites
60
T or F: BZDs in alcohol withdrawal are dosed very conservatively to avoid respiratory depression
F- aggressive dosing, but is still limited by sedation, confusion, and resp dep
61
T or F: LDs may be used for BZDs in alcohol withdrawal
T
62
how long is the length of BZD therapy for AW
usually <7d
63
list the 3 on label anticraving meds for AW
acamprosate naltrexone disulfiram
64
acamprosate MOA
may restore balance between glutamate mediated excitation and GABA mediated inhibition of neural activity + decrease neuronal hyperexcitability
65
with acamprosate, there is a significant decrease in _____ and an increase in ____________ compared to placebo
decrease in returning to drinking increase cumulative duration of abstinence by 11 days compared to placebo
66
describe the typical dosing of acamprosate
333mg PO TID F3D, then increase to 666mg PO TID
67
when should acamprosate be started
4 days after last alcohol consumption
68
when should acamprosate dosing be adjusted
CrCL 30-50 = decrease 50% avoid if CrCL <30 wt <60kg = use BID dosing
69
can acamprosate by used in pregnancy
yes- must use risk /benefit analysis not much evidence for risks, much evidence for risks of alcohol
70
what is a major pro for acamprosate
no drug interactions
71
which of the following has no drug intx 1. acamprosate 2. naltrexone 3. disulfiram 4. topiramate
1
72
acamprosate is preferred in
opioid users, those not at risk of polypharmacy
73
acamprosate AE
GI upset
74
naltrexone MOA
mu opioid receptor antagonist that blocks euphoria associated with alcohol
75
naltrexone is effective in preventing/ lowering (3)
relapse rates, # of drinking days, cravings,
76
naltrexone is dosed 1. daily 2. PRN 3. either
3
77
naltrexone CIs
acute hepatitis, severe liver dysfunction, those requiring/ taking concurrent opioids
78
naltrexone SEs
GI upset, mood, hepatotoxicity
79
naltrexone is preferred in
renal dysfunction, struggles with polypharmacy, nonopioid users
80
disulfiram works as an
alcohol deterrent tx
81
disulfiram MOA
inhibits metabolism of alcohol by blocking acetaldehyde dehydrogenase = acetaldehyde build up and causes disulfiram reaction
82
how soon does the reaction start after disulfiram + how long does it last
can happen right after alcohol ingestion + last for several hours up to 2wks
83
what are some severe reactions to disulfiram
MI, CHF, arrhythmias, resp dep, seizures, death

88
what are 2 off label treatments for AW
gabapentin topiramate
89
how might topiramate decrease AW
decreases dopamine release and alcohol cravings = decreases heavy drinking days may alter GABA function at a nonBZD site on the GABAA receptor + antagonize glutamate activity
90
topiramate SEs
paresthesias, anorexia, pruritis, difficulty concnetrating, somnolence, fatigue, confusion
91
what are managed alcohol programs? who are they targeted towards
provides prescribed doses of alcohol at regular intervals done in acute care to support those in hospital where forced detox is harmful and abstinence is not a realistic ST goal while admitted there are now also some community programs
