PT150 Drug for Use in Alcohol Use Disorder

During the alcohol administration session participants will receive a single administration of alcohol (0.5 g/kg) mixed with lemon lime soda. Participants will consume the drink within 5 min.

The stress-induction procedure is the Cold Pressure Test \[CPT\]) stressor. The bilateral foot CPT requires participants to submerge both feet in ice-cold water (24°C) for 3 minutes.

Participants will ingest PT150 (0, 225, 450 mg) twice daily (e.g., 0800, 2000h) for 5 five days prior to the conduct of the experimental sessions. The sequence of PT150 doses will be quasi-random such that participants will be maintained on the lower dose of PT150 (i.e., 225 mg twice/day) before the higher dose.
