Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate the analgesic efficacy and safety of two doses of oxymorphone immediate release (IR) compared to placebo and oxycodone in post-surgical pain.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Following abdominal surgery and after sufficient washout from post-surgical analgesia, patients were randomized to one of the following four treatment groups; 1) oxymorphone IR 10 mg, 2) oxymorphone IR 20 mg, 3) oxycodone IR 15 mg, or 4) placebo. Total duration of treatment was 48 hours. Patients were required to take the study medication every 4-6 hours. After the first dose, periodic pain assessments were performed for the first six hours. Subsequently, patients were required to assess their current pain intensity and average pain intensity since the last dose of study medication just prior to every dose.
