Study Description

Brief Summary

The purposes of this study are 1) to determine the pharmacokinetics of alcohol after experimental administration of alcohol simulating a "binge-drinking" episode in young adults 2) to determine the profile of biomarkers of acute damage and exposure/consumption to alcohol 3) to determine the pharmacokinetic parameters and evaluate the acute effects alcohol and its relationship with biomarkers.

Detailed Description

Binge drinking (BD) has become trendy among adolescents and young adults. It is defined as a pattern of drinking that reach blood alcohol concentration (BAC) to 80 mg/dl in a short period of time (2 hours), that typically occurs after 4 drinks for women and 5 drinks for men. Despite its high prevalence and association with morbidity and mortality, there are no previous experimental studies evaluating alcohol concentrations after a "binge drinking" episode neither its effects on biomarkers of acute damage and exposure/consumption.

The aims of this study are 1) to determine the pharmacokinetics of alcohol after experimental administration of alcohol simulating a "binge-drinking" episode in young adults 2) to determine the profile of biomarkers of acute damage and exposure/consumption to alcohol 3) to determine the pharmacokinetic parameters and evaluate the acute effects alcohol and its relationship with biomarkers.

Calculation of AUC of the concentrations of alcohol in blood.

Secondary Outcome Measures

Area Under the Concentration-Time Curve (AUC 0-24h) of biomarkers of acute damage and exposure/consumption in blood. [From pre-dose (base-line, 0 hour), to 2.33 hour (h), 4 h, 6 h, 8 h, 24 h post-dose. Additional samples will be collected at 7,14 and 21 days post-administration]
Calculation of AUC of the concentrations of other biomarkers of exposure/consumption in blood.
Cumulative amount of biomarkers of exposure/consumption excreted into urine up to collection time of last measurable concentration. [From pre-dose (base-line, 0 hours (h)) and following intervals 0-2h, 2-4h, 4-6h, 6-8h, 8-10h, 10-12h and 12-24h to 24h post-administration]
Urine will be collected in intervals and the total amount of biomarkers of exposure/consumption will be calculated (ethylglucuronide and ethylsulfate)

Daily consumption >20 grams of alcohol in women and >40 grams of alcohol in men.
