Does alcohol absorb to activated charcoal?

Area of Science:

• Toxicology
• Pharmacology

Background:

• Activated charcoal is rarely used for alcohol poisoning, as it is poorly adsorbed by the gut and initially found to adsorb alcohol inefficiently.
• Previous research in dogs suggested that co-administration of activated charcoal and alcohol could significantly reduce blood alcohol concentration.

Purpose of the Study:

• To investigate the clinical efficacy of activated charcoal in reducing blood alcohol concentrations.
• To determine if activated charcoal has value in managing alcohol poisoning in a human clinical setting.

Main Methods:

• A randomized cross-over study was conducted in two phases.
• Participants consumed 88 g of alcohol, followed 30 minutes later by either 20 g of activated charcoal or an equal volume of water.

Main Results:

• No statistically significant differences were observed in plasma alcohol concentrations between the group that received activated charcoal and the control group that received water.
• The findings contradict earlier animal studies suggesting a significant reduction in blood alcohol levels.

Conclusions:

• Activated charcoal does not appear to be effective in reducing blood alcohol concentrations when administered clinically alongside alcohol.
• Further research may be needed to explore alternative methods or specific conditions where activated charcoal might be beneficial in alcohol intoxication.
