Ghrelin is Supressed by Intravenous Alcohol and is Related to Stimulant and Sedative Effects of Alcohol

What Was Tested

The paper reports a study of Ghrelin, published as a clinical trial.

Evidence indicates that feeding-related peptides, such as ghrelin, have a role in the rewarding properties of addictive substances like alcohol.

Why It Was Studied

Fasting ghrelin levels also predict subjective behavioral effects of alcohol.

Those with higher fasting ghrelin levels tend to experience alcohol effects longer and more intensely.

Who Took Part

PubMed indexes the participants as young adults and adults, both men and women.

Healthy social drinkers (N = 20) participated in three, randomly assigned, and counterbalanced laboratory sessions.

Participants were given a standardized, light breakfast 90 min before the start of the infusion.

How the Study Was Run

The researchers set it up as a randomized and placebo-controlled study.

Random assignment meant chance, not the researchers, decided who got Ghrelin and who got the comparison, which limits bias.

Some participants received a placebo instead of Ghrelin, giving a reference point.

Subjective effects of alcohol, using the BAES, were evaluated before, during and after alcohol infusion.

What Was Measured

Fasting ghrelin levels also predict subjective behavioral effects of alcohol.

Those with higher fasting ghrelin levels tend to experience alcohol effects longer and more intensely.
