Measure
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. Oxycodone: 5 mg tablet Placebo: Oxycodone-matched placebo tablet EyeLink 1000 Plus: Non-invasive video-based eye tracking system Oculo-Cognitive Addition test (OCAT): Subject will have to look for numbers on a screen and add these numbers together. OCAT will be presented on a computer screen with attached eye tracking device at the bottom part. VT3mini - Eye Tracking Technology for OEMs: Non-invasive eye-tracking device
