Brief Summary:
Acute low back pain is a common cause for emergency department visits. Controversy remains regarding the optimal medication for acute low back pain relief. The investigators hypothesized that administration of pharmacological anxiolysis in addition to analgesia will improve pain relief and patient management in the emergency department.

Condition or disease Intervention/treatment Phase
Low Back Pain Drug: Morphine-Promethazine Drug: morphine Phase 4

Detailed Description:

Acute low back pain is a common problem in the emergency department and pain relief is usually the first step in patients' management. Numerous medication options are available for acute LBP relief,each class of medication has its associated benefits and harms.Controversy remains regarding the optimal analgesic treatment.Anxiety has been found to be a predictive factor of pain intensity in patients with acute low back pain and anxiolysis by non-pharmacological measures has been shown to have a positive effect on pain management in the ED setting.

Promethazine is a first-generation H1 receptor antagonist of the phenothiazine chemical class used commonly as an antihistamine antiemetic. It has a strong anxiolytic-sedative effect and its safety and efficacy in managing anxiety related to medical procedures is well documented.It may be reasonable to assume that pharmacological anxiolysis with promethazine may assist in alleviation of acute pain in the strenuous environment of the ED.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 200 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Care Provider)
Primary Purpose: Treatment
Official Title: Pharmacological Anxiolysis With Promethazine as an Adjunctive Therapy for Acute Low Back Pain in the Adult Emergency Department
Study Start Date : May 2010
Estimated Primary Completion Date : December 2011
Estimated Study Completion Date : January 2013

Arm Intervention/treatment
Experimental: Morphine-Promethazine
Pain relief by administration of morphine-promethazine combination
Drug: Morphine-Promethazine
administration of intravenous morphine 0.1mg/kg and promethazine 12.5 mg in a 500 Ml 0.9% saline
Other Name: morphine-phenergan

Active Comparator: morphine
pain relief by administration of morphine
Drug: morphine
Administration of intravenous morphine 0.1 mg/kg
Other Name: morphine as a single drug

Primary Outcome Measures :
  1. Pain relief [ Time Frame: Up to 24 hours (before analgesia administration and on discharge from the ED or admission to the hospital) ]
    Pain scores before and after treatment will be assessed on a 100mm VAS. The difference will be regarded as pain relief.

Secondary Outcome Measures :
  1. Ambulatory status [ Time Frame: Up to 24 hours (before analgesia administration and on discharge from the ED or admission to the hospital) ]
    Most patients who suffer from acute LBP are in severe pain and are unable to ambulate. The ambulatory status of every patient (e.g., able to walk independently, using a can, wheelchair, laying down and unable to sit or stand up)will be recorded before and after treatment.
