Thera 2 ETOH disorder Flashcards
NIAA definition of ETOH abuser for males is:
> 7 drinks in 2 hrs
14 drinks / week
NIAA definiton of ETOH abuser for females is:
> 3 drinks in 2 hrs
7 drinks/week
Biological markes for ETOH
AST 2x>ALT
GGT >30
dCDT >1.7
BAC >1.5
EtG+
ETOH Neuro effects are:
Enhances GABA–> Feel relax
NMDA Glutamate receptor antagonism–>Don’t feel pain
Mild opiate agonism
5-HT3 augmentation–> Vomiting
Vasodilation
Increase in gastric secretions
Diuresis–> ADH is inhibited by alcohol so pee more
Treatment for ETOH withdrawal:
1-Benzodiazepines is the prefer option
2-Can use Barbiturates like phenobarbital if the benzodiazepines are not effective
3-Propofol –> Is a GABA agonist and a NMDA receptor antagonist so decreases the glutamate activity–> Is useful in ICU but Benzos are still prefered
Treatment for alcohol withdrawal autonomic manifestation if the pt has high BP
Clonidine or dexmedetomidine a alpha 2 agonist
treatment for alcohol withdrawal Neuroleptics to reduce agitation:
Haloperidol
-Block dopamine so reduces agitation
-Give by IV
Wernicks encephalopathy symptoms
Ataxia–> poor coordination
Confusion
Ocular muscle disturbances
due to low thiamine
pt is ETOH problem need to give Thiamine (B1) supplement
Thiamine dose is
200-500mg IV TID until symptoms resolve
Can give Mg2+ and glucose supplement 20mins after
Korsakoff syndrome
Symptoms
Irriversible brain damage due to chronic thiamine (Vitamin B1) deficiency + pt is alcoholic
Symptoms:
Amnesia–> memory loss
Poor recall
Confabulation–> Pt will make fake memories
Drugs to treat Alcohol use disorder after withdrawal symptoms have been resolved:
**Disulfiram **
Antabuse
Inhibits Aldehyde dehydrogenase which lead to increase acetaldehyde levels
If the pt drink they will suffer from: Intense nausea, vomiting, tachycardia, hypotension, flushing
-Cannot give if pt has cardiac conditions like angina, MI, severe liver damage
-Cannot give if pt lives alone
Drugs to treat Alcohol use disorder after withdrawal symptoms have been resolved:
Naltrexone
PO is Revia
Injection is vivitrol
is a MU antagonist
It has anticraving effects, negative effects in the nucleus of accumbus
AE: Nausea, HA, dizziness
-Cannot give if pt has increase LFT so high AST/ALT high GGT and is HepC+ has sever liver hepatitis cirrhosis
-Pregnancy category C
-Conjugated and then renally excreted –> Is metabolize to 6-betanaltrexol
Drugs to treat Alcohol use disorder after withdrawal symptoms have been resolved:
**Acamprosate **
Campra
MOA: Enhances GABA, Ca2+ blockade, Decreases glutamate activity, may increase taurine
-Is excreted unchange so is safe to give to pt with elevated LFT levels
AE: Diarrhea, HA
Drugs to treat Alcohol use disorder after withdrawal symptoms have been resolved:
Topiramate
Topomax
MOA: Enhances GABA ; reduces glutamate signaling
Useful if Naltrexone and acamprosate have failed
AE:
-paresthesia
-HA
-Loss of taste
-Anorexia
Gabapentin
can be use in patient with high withdrawal symptoms
-has a abuse risk so shouldn’t be use in pt with substance abuse disorder
