Template:TOC-right Alcohol withdrawal is a group of syndromes that may occur after cessation of drinking ethanol alcohol.[1][2][3]

Classification

Autonomic hyperactivity

Withdrawal may cause hyperactivity of the sympathetic nervous system.

Seizures

Alcohol withdrawal seizures is a "condition where seizures occur in association with ethanol abuse (alcoholism) without other identifiable causes. Seizures usually occur within the first 6-48 hours after the cessation of alcohol intake, but may occur during periods of alcohol intoxication. Single generalized tonic-clonic motor seizures are the most common subtype, however, status epilepticus may occur".[4][5]

Delirium

Alcohol withdrawal delirium,formerly called delerium tremens, is an "acute organic mental disorder induced by cessation or reduction in chronic alcohol consumption. Clinical characteristics include confusion; delusions; vivid hallucinations; tremor; agitation; insomnia; and signs of autonomic hyperactivity (e.g., elevated blood pressure and heart rate, dilated pupils, and diaphoresis). This condition may occasionally be fatal."[6][7]

Treatment

Benzodiazepines

Benzodiazepines such as diazepam (Valium), lorazepam (Ativan) or oxazepam (Serax) are the most commonly used drugs used to reduce alcohol withdrawal symptoms. There are several treatment patterns in which it is used.

  1. One option takes into consideration the varying degrees of tolerance. In it, a standard dose of the benzodiazepine is given every half hour until light sedation is reached. Once a baseline dose is determined, the medication is tapered over the ensuing 3-10 days.
  2. Another option is to defer treatment until symptoms occur.[8][9] A non-randomized, before and after, observational study found that symptom triggered therapy was advantageous.[10]

Dosing of the benzodiazepines can be guided by the CIWA-Ar scale.[11] The scale is available online (see external links below).

Regarding the choice of benzodiazepine:

  • Chlordiazepoxide (Librium®) is the benzodiazepine of choice in uncomplicated alcohol withdrawal. [12]
  • Lorazepam or diazepam are available parenterally for patients who cannot safely take medications by mouth.
  • Lorazepam and oxazepam may be best in patients with cirrhosis (shorter half life).

Adrenergic antagonists

Number of treatment failures due to severe hallucinations or alcohol withdrawal.
Chlordiazepoxide
Given Not given
Propranolol Given 1 4
Not given 0 4
Notes:
1. There were 15 patients in each group.

2. Not shown is the arrhythmia scores,
which were best in the groups receiving propanolol.

Randomized controlled trials have found benefit from sympatholytics such as atenolol[13] and clonidine.[14] In the major trial, atenolol was given to patients without contraindications at a dose of 50 mg if the pulse was 50-79 and 100 mg if the pulse was 80 or more.[13] Clonidine was administered to patients without contraindications as 0.2 mg per dose with the schedule of day 1 at 9pm; day 2 at 9am, 1pm, and 6pm; day 3 9am and 6pm; and day 4 at 9am.[14]

A factorial randomized controlled trial[15] has been misinterpreted leading to concerns that beta-blockers are associated with hallucinations.[1] However, the table at right shows that in the factorial study, the hallucinations were associated with the absence of chlordiazepoxide and not the presence of propanolol. The combination of both propanolol and chlordiazepoxide gave the best combination of reduction in withdrawal symptoms and arrhythmias.[15]

A case report shows that beta-blockers may remove signs of hyperactivity of the sympathetic nervous system thus leading to overlooking a diagnosis of delirium tremens in a chronic alcholic with hallucinations after stopping alcohol.[16] Thus clinicians should not require the presence of sympathetic hyperactivity in diagnosing delirium tremens in a patient receiving beta-blockers.

Carbamazepine

A randomized controlled trial has found benefit from carbamazepine.[17]

Other drugs

Sodium oxybate is the sodium salt of gamma-hydroxybutyric acid (GHB). It has been studied for both acute alcohol withdrawal[18] and medium to long-term detoxification[19]. This drug enhances neurotransmission by the inhibitory neurotransmitter gamma aminobutyric acid (GABA) and reduces levels of the excitatory neurotransmitter glutamate.

Baclofen has been shown in animal studies and in small human studies to enhance detoxification[20] and maybe reduce craving[21]. This drug acts as a GABA B receptor agonist.

Some hospitals administer alcohol to prevent alcohol withdrawal although there are potential problems with this practice.[22]
