Open-Label Study of Oxycodone/APAP to Treat Post-Operative Pain Following Arthroscopic Knee Surgery

Open-Label Parallel Group Flexible Dosing & Titration Study to Evaluate the Efficacy, Safety of Oxycodone/APAP Extended Release Formulation Xartemisxr® in the Management of Post-Operative Pain Following Outpatient Arthroscopic Knee Surgery

This is a pilot trial using this product in patients for the management of pain after outpatient arthroscopic knee surgery. This is an open-label study and the two active ingredients are well known pharmacologic entities.

The objective of this single center is to evaluate the safety and efficacy of Oxycodone Extended Release (MNK-795) in postoperative pain following common musculoskeletal surgical procedures. Knee surgery being the most common surgery performed in the US, the investigators chose the model. The investigators also want to look at the flexible-dosing and titration which is the common way pain managed by clinicians. This is an open-label study of MNK 795 to be described in the procedures section.
