Conditions

Healthy

Keywords

food effect; pharmacokinetics; bioavailability; oxycodone; management of moderate to severe pain

Outcome Measures

Primary Outcomes (2)

• Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - 8)]

  AUC (0 - 8)= Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0 - 8). It is obtained from AUC (0 - t) plus AUC (t - 8).

  0,0.5,1,2,3,4,5,6,8,10,12,16,24,36,48 hours post-dose

• Maximum Observed Plasma Concentration (Cmax)

  0,0.5,1,2,3,4,5,6,8,10,12,16,24,36,48 hours post-dose

Secondary Outcomes (4)

• Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast)

  0,0.5,1,2,3,4,5,6,8,10,12,16,24,36,48 hours post-dose

• Concentration at time 24 hours (C24) of oxycodone, as data permit.

  0,0.5,1,2,3,4,5,6,8,10,12,16,24,36,48 hours post-dose

• Time to Reach Maximum Observed Plasma Concentration (Tmax)

  0,0.5,1,2,3,4,5,6,8,10,12,16,24,36,48 hours post-dose

• Plasma Decay Half-Life (t1/2)

  0,0.5,1,2,3,4,5,6,8,10,12,16,24,36,48 hours post-dose
