3 Clinical Trials for Various Conditions
The purpose of this study is to investigate if 28 days of treatment with AZD2066 compared to placebo can relieve the pain arising from the nervous system when the patients are touched by something that should not cause pain or have severe pain when they are touched by something that should only cause a little pain.
Chronic pain in patients following total hip replacement seems to be a significant problem. Previous research has shown that more effective pain management in the early postoperative period may decrease the incidence of the development of chronic pain states. This study will evaluate whether ketorolac (a non steroidal anti-inflammatory drug) given into the spinal fluid before surgery will reduce the area of sensitivity (or pain to light touch) following surgery. Patients will be monitored during their postoperative hospital stay and then contacted by telephone at 8 weeks and 6 months after surgery and questioned about any pain they are having at their surgical site. Patients that are still experiencing pain at 6 months will be asked to return to the medical center for the study staff to assess their pain or sensitivity at the surgical site.
