Outcome Measures
Primary Outcomes (2)
Percentage of Participants With Reduction in Pain Intensity
The percentage of participants with extent of reduction in pain intensity greater than or equal to 30 percent was reported. Pain intensity change rate was calculated by Visual Analog Scale (VAS) score at baseline minus VAS score at Day 29 divided by VAS score at Baseline. VAS is a 10 centimeter (cm) scale. Intensity of pain range: 0 cm=no pain to 10 cm=worst possible pain.
Baseline up to Day 29
Change From Baseline in Pain Intensity at Day 29
Change in pain intensity experienced by participants over the last 48 hours was measured on Day 29 against Baseline with VAS. VAS is a 10 cm scale. Intensity of pain range: 0 cm=no pain to 10 cm=worst possible pain.

Study Arms (2)
Tramadol Hydrochloride (HCl)/acetaminophen
EXPERIMENTALParticipants will receive 1 tablet containing fixed dose of combination of tramadol hydrochloride (HCl) 75 milligram (mg) /acetaminophen Extended Release (ER) 650 mg orally once daily on Days 1 to 3, 1 tablet twice daily (tramadol HCl 150 mg/acetaminophen 1300 mg) on Days 4 to 7, then 1 or 2 tablets twice daily on Days 8 to 28.
Placebo
PLACEBO COMPARATORPrticipants will receive 1 tablet matching placebo once daily orally on Days 1 to 3, 1 tablet twice daily on Days 4 to 7, then 1 or 2 tablets twice daily on Days 8 to 28.
Interventions
Participants will receive 1 tablet containing 75 mg of tramadol HCl and 650 mg of acetaminophen, once daily on Days 1to 3, then 1 tablet twice daily on Days 4 to 7
Participants will receive 1 matching placebo tablet once daily on Days 1 to 3, then 1 tablet twice daily on Days 4 to 7
Eligibility Criteria
You may qualify if:
- Participants diagnosed with low back pain at least 3 months before the screening or washout period
- Participants who have taken a stable dose of Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) (drugs used for reducing inflammation and pain ) or Cyclo-Oxygenase 2 (COX-2) selective inhibitors (an anti-inflammatory drug that fights pain) from 7 days before investigational product administration, and could maintain the same dose during the period of the study
- Participants whose average pain intensity is more than or equal to 4.0 centimeters on Visual Analog Scale over the last 48 hours after the completion of screening
- Postmenopausal or surgically sterile or abstinent women or practicing a highly effective method of birth control
- Women with childbearing potential must have negative pregnancy test
You may not qualify if:
- Participants who have taken tramadol or tramadol HCl or acetaminophen, or narcotic (strong habit-forming drug that stops pain and depresses the central nervous system) analgesic tablet within 30 days before investigational product administration
- Participants who have taken acetaminophen tablet within 7 days before investigational product administration
- Participants with tumor or infection in meninges or spinal cord
- Participants who have fibromyalgia (neurosensory disorder characterized by muscle pain, joint stiffness, and fatigue), reflex sympathetic dystrophy (feeling of pain associated with evidence of minor nerve injury) or causalgia (persistent, severe burning sensation of the skin), acute spinal cord compression, acute nerve root compression, severe lower extremity weakness or numbness, regional pain syndrome, meningitis (inflammation of the meninges), diskitis (nonbacterial inflammation of an intervertebral disk or disk space), back pain because of secondary infection or tumor, or pain caused by a confirmed or suspected neoplasm
- Participants who have taken analgesic (including local agents or anesthetics), sedative-hypnotic (e.g., diazepam), or muscle relaxant other than a stable dose of NSAIDs or COX-2 selective inhibitors within 5 times the half-life of the concerned agent before investigational product administration
