Ethanol (EtOH)
A CNS depressant that activates GABA receptors, producing sedation and impaired motor function.
GABA Receptor Activation
Enhancement of inhibitory neurotransmission leading to CNS depression; mechanism shared by alcohol and benzodiazepines.
Alcohol Intoxication
Clinical state marked by slurred speech, ataxia, stupor, or coma after excessive drinking.
Alcohol Intoxication Management
Supportive care plus thiamine and folate; gastric evacuation only if large ingestion occurred within the last hour.
Benzodiazepines
Sedative–hypnotic drugs that potentiate GABA-A chloride channels to reduce anxiety and induce sleep.
Benzodiazepine Intoxication
Drowsiness, confusion, slurred speech, incoordination, and ataxia resembling alcohol intoxication.
Flumazenil
A competitive benzodiazepine antagonist used to reverse benzodiazepine overdose.
Alcohol Withdrawal
Symptom spectrum occurring after cessation of heavy drinking, ranging from tremors to delirium tremens.
Mild Alcohol Withdrawal
Anxiety, tremors, diaphoresis, palpitations, and insomnia appearing 6–24 hours after last drink.
Alcoholic Seizures
Generalized tonic–clonic seizures that emerge 24–48 hours after alcohol cessation.
Alcoholic Hallucinosis
Visual, auditory, or tactile hallucinations with normal orientation and stable vitals, 24–48 hours after last drink.
Delirium Tremens
Severe alcohol withdrawal (48–96 h) featuring confusion, hallucinations, fever, and hypertension.
CIWA Scale
Clinical Institute Withdrawal Assessment tool used to gauge alcohol withdrawal severity and guide benzodiazepine dosing.
Diazepam
Long-acting benzodiazepine preferred for alcohol withdrawal in patients with normal liver function.
Lorazepam
Intermediate-acting benzodiazepine used for alcohol withdrawal in liver-impaired patients.
Banana Bag
IV mixture of thiamine, folate, and vitamins given to chronic alcohol users to prevent deficiency complications.
Benzodiazepine Withdrawal
Alcohol-like symptoms (anxiety, tremors, seizures, hallucinations) requiring slow taper with a long-acting benzodiazepine.
Alcohol Use Disorder
Maladaptive pattern of alcohol use causing impairment or distress, characterized by tolerance, cravings, and failed obligations.
Wernicke’s Encephalopathy
Thiamine-deficiency triad of nystagmus, ophthalmoplegia, and ataxia with confusion; precipitated by glucose administration.
Korsakoff Syndrome
Chronic amnestic disorder with confabulation and apathy due to untreated Wernicke’s; usually irreversible.
Naltrexone
Opioid receptor antagonist that reduces alcohol craving and reward; contraindicated in severe hepatitis.
Acamprosate
Glutamate modulator started after detox to prevent relapse; safe in liver disease but avoided in severe CKD.
Disulfiram
Aldehyde dehydrogenase inhibitor causing flushing, headache, vomiting, and palpitations if alcohol is consumed.
CAGE Questionnaire
Four-item screening tool (Cut down, Annoyed, Guilty, Eye-opener) for identifying problem drinking.
AUDIT
