Primary Objective: Characterize the pharmacokinetics of ethanol in participants receiving maintenance Glucagon-like peptide-1 (GLP-1) receptor agonist (RA) therapy (tirzepatide).
Secondary Objectives:
- Determine the effects of GLP-1 RA therapy on alcohol-induced impairment, as measured by
- objective performance
- subjective impairment assessments
- risk perception
Correlative Objectives
- Define the exposure-response relationship between biological alcohol concentrations (breath and blood) and functional impairment to determine if Primary Objective
- Characterize the pharmacokinetics of ethanol in participants receiving maintenance GLP-1 RA therapy (tirzepatide).

Eksperimentel: Healthy adults on Tirzepatide
Participants will complete a screening and enrollment visit, one study visit, and a follow-up correspondence over the course of approximately 4 weeks.
|
Time 0, participants will self-administer an oral ethanol beverage (vodka and sugar-free cherry Kool aid) calculated to reach a peak Breath Alcohol Concentration (BrAC) of 0.08 g/dL using the Widmark formula.
A total time of 30 minutes will be given for completion of beverage consumption.
This will be followed by a breakfast.

Biphasic Alcohol Effects Scale (BAES) Score
Tidsramme: 5 minutes, 35 minutes, 65 minutes, 95 minutes, 125 minutes, 185 minutes, 245 minutes, 290 minutes, 340 minutes
|
The BAES has 2 subscales: Stimulant scored from 0-70 and Sedative scored from 0-70.
Higher scores indicate higher stimulant or sedative effects.

Tidsramme: 5 minutes, 35 minutes, 65 minutes, 95 minutes, 125 minutes, 185 minutes, 245 minutes, 290 minutes, 340 minutes
|
To quantify cognitive and affective dimensions of risk perception, participants will complete the RPSA questionnaire assessing cognitive and affective risk perception, behavioral risk willingness, metacognitive calibration, and consequence awareness.
This RPSA has been designed by the study team to provide a low burden (12-item), repeatable measure of cognitive, affective, and behavioral dimensions of risk perception, and direct quantification of willingness to engage in safety sensitive behavior.
Scores range from 0-100 where higher scores indicate increased risk perception.

Divided Attention Task (DAT)
Tidsramme: prior to dosing (-20 minutes), 10 minutes, 100 minutes, 220 minutes
|
Participants will be asked to complete a computer-based DAT on a laptop in their room.
The DAT requires participants to track a moving stimulus on a computer screen while simultaneously monitoring numbers located in the corners of the screen.
Participants must respond to target numbers as they appear, and the task quantifies the mean distance of the mouse cursor from the center of the target stimulus.

Digital Symbol Substitution Task (DSST)
Tidsramme: prior to dosing (-20 minutes), 10 minutes, 100 minutes, 220 minutes
|
Participants will be asked to complete a computer-based DSST on a laptop in their room.
The DSST asks participants to recreate patterns of various shapes presented on a computer screen using the keyboard.
The total number of correct patterns are recorded within 90 seconds.
