Arms and Interventions

Arm Intervention/Treatment
Experimental: Treatment A

Single dose of 5 mg PF-00345439 under naltrexone block (50 mg of naltrexone administered by mouth 12 hours before, 30 minutes before, and 12 hours after study drug administration).

Drug: Oxycodone
One capsule of 5 mg PF-00345439 Formulation K, single dose, under fed conditions

Experimental: Treatment B

Single dose of 20 mg PF-00345439 under naltrexone block (50 mg of naltrexone administered by mouth 12 hours before, 30 minutes before, and 12 hours after study drug administration).

Drug: Oxycodone
One capsule of 20 mg PF-00345439 Formulation K, single dose, under fed conditions

Experimental: Treatment C

Single dose of 40 mg PF-00345439 under naltrexone block (50 mg of naltrexone administered by mouth 12 hours before, 30 minutes before, and 12 hours after study drug administration).

Drug: Oxycodone
One capsule of 40 mg PF-00345439 Formulation K, single dose, under fed conditions

Outcome Measures

Primary Outcome Measures

  1. Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - 8)] [0,0.5,1,2,3,4,5,6,8,10,12,16,24,36,48]

    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).

  2. Maximum Observed Plasma Concentration (Cmax) [0,0.5,1,2,3,4,5,6,8,10,12,16,24,36,48]

Secondary Outcome Measures

  1. 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]

    Area under the plasma concentration time-curve from zero to the last measured concentration (AUClast)

  2. Concentration at time 24 hours (C24) [0,0.5,1,2,3,4,5,6,8,10,12,16,24,36,48]

  3. Time to Reach Maximum Observed Plasma Concentration (Tmax) [0,0.5,1,2,3,4,5,6,8,10,12,16,24,36,48]

  4. Plasma Decay Half-Life (t1/2) [0,0.5,1,2,3,4,5,6,8,10,12,16,24,36,48]

    Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.
