Alcohol Use Disorders Flashcards
Temperance movement
Began in the 1784 when Dr. Benjamin Rush documented problems of heavy drinking including:
- jaundice
- delirium
- seizures
first documented cases of alcohol poisoning/addiction
What year was the peak of alcohol consumption in the US
1980
What percentage of Americans abstain?
30 percent of Americans
How does education and alcohol consumption correlate
Positive linear correlation
Where is most alcohol absorbed?
Small intestine (most)
Stomach (the rest)
*slower if food or water is in the stomach, faster if carbonated beverages are present *
Metabolism of alcohol
Zero pass metabolism in the liver
- 0.25 ounces per hour
Alcohol -> Ethanol acetaldehyde -> acetic acid
* ethanol acetaldehyde build up is toxic and makes you puke*
Alcohol use disorder DSM-5 difference
Alcohol use disorder (AUD) with mild/moderate/severe sub-classifications
- needs at least 2 of the 11 criteria in a 12 month period
Alcoholics Anonymous
Established in 1935. Follows the “12 step” program
Better for maintenance but not actually that good for stopping first
Acamprosate
Indicated for abstinence from alcohol in patients dependent
- blocks NMDA receptors and lowers cravings
Disulfriam (antibuse)
Blocks aldehyde-dehydrogenase and induces toxicity and vomiting when someone drinks
Used in patients who want to remain in a state of enforced sobriety.
- very challenging to get a patient on but is very good
Naltrexone
Indicated for the treatment of alcohol dependence
- blocks m-opioid receptors and stops dependence
- can be in oral or extended injectable forms*
- injectable forms are only used in patients who can show they are trying to remain abstain from alcohol in outpatient settings
How to handle alcohol withdrawal
Dont drink non-caffeinated fluids
Take multivitamin
Take oral thiamine
*once hitting alcoholic psychosis and delirium tremens (use benzos)
What cytochrome p450 enzyme is hyperactive in chronic alcohol use and contributes to tolerance?
CYP2E1
- if taking alcohol, can decrease metabolism of certain drugs including the following:*
- anesthetics
- acetaminophen
- eszopiclone
these drugs would also increase metabolism if the alcoholic is not drinking currently
Why do women often tend to be susceptible to alcohol effects more than men?
Women tend to:
- weigh less
- low weight = more susceptible*
- have higher proportion of body fat
- increased body fat = more susceptible*
- less alcohol dehydrogenase activity
- lower = more susceptible*
High yield effects of alcohol on common receptors and drugs
Barbiturates and benzos = synergistic effect
Glutamate = Anataognist effect (blocks receptors and also turns GABAa on more)
