ClinicalTrials.gov Identifier:
NCT01028079
First received: December 8, 2009

History: No changes posted
  Purpose

The purpose of this study is to determine the efficacy and safety of 1000 mg Aspirin (the study medication) by comparing it to placebo (the control group without active substance) or 400 mg Ibuprofen (the control group with an active substance) in treating the symptoms of back pain. The study is designed to develop a treatment method against back pain which will have more advantages for patients than the methods that are currently available.
