Understanding Alcohol: Effects, Metabolism, and Treatment

TLDRAlcohol activates GABA and serotonin receptors while inhibiting glutamate receptors, leading to sedation. The enzyme alcohol dehydrogenase metabolizes alcohol to acetyl aldehyde, which is then broken down by aldehyde dehydrogenase. People of Asian descent have less aldehyde dehydrogenase, making them more susceptible to alcohol intoxication. Screening tools for alcohol use disorder include MAST, ADI Screening Inventory, AUDIT, and CAGE questionnaire. Absorption and elimination rates of alcohol depend on factors like age, gender, weight, and speed of consumption. Blood alcohol levels impact physiological states. Treatment for alcohol dependency includes AA meetings, Smart Recovery, aversion therapy with disulfiram, and medication like naltrexone.

Key insights

🍷Alcohol activates GABA and serotonin receptors, leading to sedation

🍺Alcohol inhibits glutamate receptors, further contributing to sedating effects

🍾Alcohol metabolism involves alcohol dehydrogenase converting it to acetyl aldehyde

🥃Aldehyde dehydrogenase breaks down acetyl aldehyde into acetate or acetic acid

🍹People of Asian descent have lower aldehyde dehydrogenase levels, making them susceptible to alcohol intoxication

Q&A

What are the screening tools for alcohol use disorder?

—Screening tools for alcohol use disorder include MAST, ADI Screening Inventory, AUDIT, and CAGE questionnaire.

What factors influence the absorption and elimination rates of alcohol?

—Factors like age, gender, weight, speed of consumption, presence of food in the stomach, nutritional status, chronic alcoholism, and cirrhosis of the liver influence the absorption and elimination rates of alcohol.

What are the risks of alcohol intoxication?

—Alcohol intoxication can result in facial flushing, extreme nausea, impaired thought and judgment, motor function depression, confusion, stupor, and even coma or death.

What treatment options are available for alcohol dependency?

—Treatment options for alcohol dependency include AA meetings, Smart Recovery, aversion therapy with disulfiram, and medication like naltrexone.

What are the side effects of disulfiram and naltrexone?

—Disulfiram can cause facial flushing, headache, tachycardia, and vomiting. Naltrexone can cause nausea, vomiting, decreased appetite, and local reactions at the injection site.
