Q

What’s are the questions in the CAGE questionnaire? What’s a positive response? What do you do with a positive response?

A

Positive response is answering yes to at least 2 of the following:
Have you ever felt you should CUT down on drinking?
Have people ANNOYED you by criticizing drinking?
Have you ever felt GUILTY about drinking?
Have you ever needed an EYE-OPENER (drink first thing in morning for nerves / hangover)?
Positive result isn’t diagnostic. It means further assessment is warranted.

Q

Mild symptoms of EtOH withdrawal?

A

Tremor, insomnia, anxiety, irritability, sweating, nausea, vomiting.

17
Q

Severe symptoms of EtOH withdrawal?

A

Seizures, hallucinations, autonomic hyperactivity, DTs. These can be lethal!

18
Q

How common is it for patients to need inpatient detox for EtOH?

A

Less than 10% of people with EtOH need it - but it’s important that they get it when they do.

19
Q

4 goals of rehabilitation?

A

Enhance function
Increase motivation for abstinence
Restructure life without EtOH
Prevent relapse

20
Q

Preferred treatment modality for rehab?

A

Psychosocial intervention + pharmacotherapy.

21
Q

Is one form of psychosocial intervention shown to work better than the rest?

A

Not really. They all seem to work pretty well when people are motivated.

22
Q

3 drugs approved for alcohol dependence?

A

Disulfiram (antabuse)
Naltrexone (ReVia/Vivitrol)
Acamprosate (Campral)

23
Q

Why, practically, might disulfiram work?

A

It’s more that people are afraid of the getting sick when drinking - as opposed to getting sick from it and then not drinking.
(People put on ineffectively low dose of disulfiram remained abstinent better than people on full dose who were told it might be placebo).

24
Q

Review: Disulfiram MoA?

A

Inhibits acetaldehyde dehydrogenase. Drinking -> instant terrible hangover.

25
Q

Naltrexone MoA? Common result of treatment?

A

Opiate receptor antagonist. It takes away the positive effects of alcohol without making people sick. Prevents relapse to heavy drinking, but doesn’t promote abstinence.

26
Q

Side effect profile of naltrexone?

A

As it’s blocking endogenous opiate agonists, it makes you feel a little crappy: nausea, headaches, fatigue, anxiety.
But it’s nothing severe.
According to professor (who consults for / is on advisory board for Alkermes, who makes Vivitrol), naltrexone should be given to every EtOH-dependent patient who can take it.

27
Q

2 contraindications for naltrexone?

A

Current use of opioids -> can cause withdrawal or insufficient pain management.
Pregnancy or breastfeeding.

28
Q

What is Vivitrol?

A

Injectable, 1x / mo, long-acting naltrexone contained in polylactide microspheres.
(seems pretty cool, but again, be aware of Dr. Kranzler’s conflict of interest here)

29
Q

What’s weird about acamprosate efficacy?

A

It was worked well in European studies for EtOH use disorders, but these results can’t be replicated in the US.

30
Q

Who can’t you use acamprosate in?

A

People with renal insufficiency. But you can use it in people with liver disfunction.

31
Q

Is topiramate approved to treat alcohol dependence? MoA? Efficacy? Downside.

A

No, and it probably won’t be, as it’s off-patent. It’s an anticonvulsant. It appears to be effective. Lots of bad side effects.
