A Study to Determine the Fed Bioequivalence of Reformulated OXY Tablets and Original OxyContin® (OXY) Tablets

A Randomized, Open-Label, Single-Center, Single-Dose, Two-Way Crossover Study in Healthy Subjects to Determine the Fed Bioequivalence of Oxycodone Tamper Resistant (OTR) 40-mg Tablets to OxyContin® 40-mg Tablets

To assess the bioequivalence of reformulated OXY tablets (40 mg) relative to the original OxyContin® (OXY) formulation (40 mg) in the fed state.

Study Overview

• Status: Completed
• Conditions: Healthy Volunteers
