Overview

Brief Summary

Research is being conducted to better understand the physiologic effects (relating to the action of a drug when taken by a healthy person) of opioid use on oculomotor (relating to the motion of the eye) dynamics and to identify the presence of characteristics consistent with a specific drug or class of drugs.

Arms & Interventions

Oxycodone, Then Placebo

Participants first receive initial dose of oxycodone 5 mg tablet followed by a 30-minute rest period to allow for onset of medication effect. This rest period will be followed by a standardized set of oculomotor testing for 40 minutes. After the initial testing, a second dose of oxycodone 5 mg tablet will be administered followed by a 30-minute rest period to allow for the onset of the second dose. The second rest period will be followed by a second round of standardized oculomotor testing for 40 minutes. Participants will then return approximately 4 to 6 days to repeat the standardized oculomotor testing with placebo.
