What are the Key Steps in the metabolism of alcohol
Alcohol -> Acetaldehyde (via alcohol dehydrogenase)
Acetaldehyde -> Acetic Acid (via acetaldehyde dehydrogenase)

What is the meaning of Zero-Order Kinetics?
The Rate of metabolism remains constant and is independent of concentration or amount of the chemical
What to look for in acute alcohol intoxication ?
- monitor respiratory depression and aspiration of vomitus
- Glucose can treat metabolic alterations such as hypoglycemia and ketosis

- reduces the craving for alcohol and the rate of relapse
- must be opioid-free before initiating therapy
What is the MOA of Acamprosate?
It is a weak NMDA receptor antagonist and GABA A receptor agonist
-Reduces short-term and long-term relapse rates
What is the MOA for Disulfiram?
Irreversibly inhibits aldehyde dehydrogenase and causes extreme discomfort in patients who drink alcohol
