===Alcohol withdrawal delirium===
Alcohol withdrawal delirium 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. It was formerly called delirium tremens".

Alcohol withdrawal is a group of syndromes that may occur after cessation of drinking ethanol alcohol.[1]

Classification

Alcohol withdrawal associated autonomic hyperactivity

Alcohol withdrawal 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".[2][3]

Alcohol withdrawal delirium

Alcohol withdrawal delirium 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. It was formerly called delirium tremens".[4][5]

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. The first 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 give a standard dose of benzodiazepine based on history and adjust based on withdrawal phenomenon.
  3. A third option is to defer treatment until symptoms occur. This method should not be used in patients with prior alcohol related seizures. This has been effective in randomized controlled trials.[6][7] A non-randomized, before and after, observational study found that symptom triggered therapy was advantageous.[8]

Dosing of the benzodiazepines can be guided by the CIWA-Ar scale.[9] The scale is available online.[10]

Regarding the choice of benzodiazepine:

  • Chlordiazepoxide (Librium®) is the benzodiazepine of choice in uncomplicated alcohol withdrawal. [11]
  • 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).

Sympatholytics

Randomized controlled trials have found benefit from atenolol[12] and clonidine.[13]

Carbamazepine

A randomized controlled trial has found benefit from carbamazepine.[14]

Other drugs

Some hospitals administer alcohol to prevent alcohol withdrawal although there are potential problems with this practice.[15]

Various vitamins, especially from the B group, are often used during withdrawal treatment.

Sodium oxybate is the sodium salt of gamma-hydroxybutyric acid (GHB). It is used for both acute alcohol withdrawal and medium to long-term detoxification. This drug enhances GABA neurotransmission and reduces glutamate levels. It is used in Italy in small amounts under the trade name Alcover.

Baclofen has been shown in animal studies and in small human studies to enhance detoxification. This drug acts as a GABA B receptor agonist and this may be beneficial.
