What this trial studies

This clinical trial investigates the effectiveness of Haloperidol for pain control in patients aged 18-65 who present to the emergency department with acute, non-traumatic back pain. A total of 150 participants will be enrolled and randomly assigned to receive either Haloperidol or Ketorolac Tromethamine. Pain levels will be assessed at 30, 60, and 90 minutes after administration, with follow-up conducted via telephone 24 hours later. The study aims to provide insights into alternative pain management strategies in emergency settings.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-65 presenting with acute, non-traumatic back pain and a pain score greater than 5 cm on the VAS.

Not a fit: Patients with traumatic back pain, neurological abnormalities, or certain medical conditions such as glaucoma or Lewy Body Dementia may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could offer a new approach to managing acute back pain in emergency department settings.

How similar studies have performed: While the use of Haloperidol for pain management is not widely tested, similar studies have explored its efficacy in various pain conditions, indicating potential for success.
