Study to Determine the Effects of Co-Administration of Alcohol on the Absorption of Oxycodone From a Proprietary Controlled-Release Formulation

This study has been completed.
Information provided by (Responsible Party):
Pfizer Identifier:
First received: August 29, 2012
Last updated: December 10, 2012
Last verified: December 2012
The study is designed to test whether or not the rate and extent of absorption of oxycodone from a proprietary controlled-release formulation is significantly affected by co-administration of alcohol compared with controlled conditions (when the formulation is administered with water). The primary pharmacokinetic parameters are the peak concentration of oxycodone (Cmax) and the overall exposure level of oxycodone as represented by the area under the plasma concentration-time curve (AUC).

Condition Intervention Phase
Drug: Test formulation administered with water
Drug: Test formulation administered with 20% ethanol
Drug: Test formulation administered with 40% ethanol
Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Open Label
Primary Purpose: Basic Science
Official Title: An Open-label, Single-dose, Randomized, Three-way Crossover Study to Estimate the Effects of Ethanol 20% and 40% on the Bioavailability a Controlled Release Formulation of Oxycodone 20 Mg With Sequestered Naltrexone 2.4 Mg in Healthy Volunteers
