Q

Q

Role of GABA and alcohol withdrawal

A
  • Alcohol potentiates GABA → diminishes receptor sensitivity
  • Chronic use of alcohol → reduced potentiation of GABA-mediated chloride flux through the GABAA receptor channel complex ⇒ tolerance
20
Q

GABA-mediated neurotransmission is decreased in alcohol withdrawal, leading to the _____ symptoms

Thus ______, which also potentiate GABA, are effective against some of the withdrawal symptoms.

A
  • hyperactivity
  • benzodiazepines
21
Q

Role of glutamate in alcohol withdrawal

A

Alcohol inhibits glutamate at the NMDA receptor→ patient feels calm → chronic use up regulates receptors → alcohol abstinence increases activated tone.

(partial seizures, anxiety & sleep problems)

22
Q

Alcohol withdrawal symptoms (8)

A
  1. Autonomic hyperactivity (sweating or HR > 100)
  2. Anxiety
  3. Insomnia
  4. Hallucinations or Illusions (Transient)
  5. Psychomotor agitation
  6. Tremor (hands)
  7. Seizures
  8. N/V

(2 or more of the these → alcohol withdrawal)

23
Q

Alcohol withdrawal is called

A

Delirium tremens

(because withdrawal can lead to delirium)

24
Q

Alcohol withdrawal delirium symptoms usually develop shortly after or during withdrawal symptoms and include:

A
  1. Disturbance of consciousness with reduced ability to focus, sustain or shift attention
  2. Change in cognition (such as memory deficits, disorientation, or language) or perceptual disturbance
  3. Fluctuates during the course of the day
25
Q

Alcohol withdrawal begins within ______ after sensation or significant decrease in use.

A
  • 12 to 18 hours

(Dr. Slagle says 18-24 hours is more realistic)

26
Q

Treatment of alcohol withdrawal (4)

A
  1. Benzodiazepines (BZD’s) (works similarly to alcohol in binding to GABA receptor) or chlordiazepoxide
  2. Day 1: aim to markedly depress the withdrawal symptoms, then decrease that amount by 20% over the next four days
  3. Replace fluids
  4. Thiamine and folic acid

(Usually accomplished in 5 days)

27
Q

When are long-acting BZD used to treat alcohol withdrawal?

A

Those who do not have severe liver disease or brain damage

(diazepam or chlordiazepoxide)

28
Q

Long-acting benzodiazepines used for alcohol withdrawal

A
  1. Diazepam
  2. Chlordiazepoxide
29
Q

Short-acting drugs used for alcohol withdrawal

A
  1. Oxazepam
  2. Lorazepam

(more frequent dosing for those with liver or brain damage)

30
Q

Treating alcohol withdrawal with anticonvulsants such as _______ (3) will prevent seizures, preserve cognition and may aid in relapse prevention.

  2. carbamazepine
  3. gabapentin
31
Q

Getting patients into treatment: 40% of medical and patient admissions are related to complications of alcohol dependence. Substance use disorders are often undetectable and undiagnosed. How do you help these patients?

40
Q

Disulfiram (antabuse) FDA approved for managing _____.

A

chronic alcoholics who wish to remain abstinent so that psychotherapeutic treatment might be most effective

Dose of disulfiram is usually _____ daily. If the patient decides they want to stop Disulfiram and continue to drink they must wait ______days

A
  • 250 mg
  • 5
42
Q

Opioid antagonist: Alcohol consumption affects the production, release and activity of ____.

A

opioid peptides

43
Q

Opioid peptides mediate some of alcohol’s rewarding effects by enhancing ________.

midbrain dopamine (DA) release

(Genetic high risk/FH+ individuals have an exaggerated alcohol-induced rise in Beta-endorphin levels. Naltrexone tx decreases pleasurable effects of EtOH)

44
Q

________ drug may work best in those whose alcoholic disease is characterized by craving.
