Primary Outcome Measures:
  • Buprenorphine effects on Healthy volunteers [ Time Frame: up to 96 hours ] [ Designated as safety issue: No ]
    These outcomes will be measured by blood and urine collection, and pupil measurements taken during the study days and follow-ups.


Secondary Outcome Measures:
  • Buprenorphine clearance from the body [ Time Frame: Up to 96 hours ] [ Designated as safety issue: No ]
    These outcomes will be measured by blood and urine collection, taken during the study days and follow-ups.

  • Buprenorphine metabolism [ Time Frame: up to 96 hours ] [ Designated as safety issue: No ]
    These outcomes will be measured by blood and urine collection, taken during the study days and follow-ups.

  • Buprenorphine bio-availability [ Time Frame: up to 96 hours ] [ Designated as safety issue: No ]
    These outcomes will be measured by blood and urine collection taken during the study days and follow-ups.

  • Buprenorphine pupil diameter changes [ Time Frame: up to 96 hours ] [ Designated as safety issue: No ]
    These outcomes will be measured by pupil measurements taken during the study days and follow-ups.
