Study Arms (2)
1- Lidoderm®
EXPERIMENTALLidoderm (lidocaine patch 5%), up to three patches applied topically once daily (q24h) to the area of maximal peripheral pain
2-Placebo
PLACEBO COMPARATORMatching placebo, up to three patches applied topically once daily (q24h) to the area of maximal peripheral pain
Interventions
Eligible patients were randomized equally to one of two groups: lidocaine patch 5% or matching placebo patch. During the 6-week treatment period, patients used up to three patches daily applied q24h.
Eligibility Criteria

- Were currently experiencing moderate/severe pain despite current analgesic treatment
- Had daily moderate-to-severe LBP for at least 3 months duration
- Had a mean daily pain intensity score of \>6 on a 0 to 10 scale, with 0 being no pain and 10 being pain as bad as the patients have ever imagined (Question 5 of BPI) during the baseline week; patients had to complete daily diary assessments at least 5 of 7 days during the baseline week
You may not qualify if:
- Had a history of greater than one back surgery, or one back surgery within 3 months of study entry
- Had severe spinal stenosis
- Had chronic back pain of \>12 months duration with an undefined spinal diagnosis
- Had radicular symptoms with radiation into the thigh or below (i.e., knee, calf, foot, etc.)
- Had received an epidural steroid/local anesthetic injection within 2 weeks prior to study entry
- Had received trigger point injections within 2 weeks prior to study entry
- Had received Botulinum Toxin Injections for LBP within 3 months prior to study entry
- Were taking a lidocaine-containing product that could not be discontinued while receiving study medication
- Were taking class 1 anti-arrhythmic drugs (e.g., mexiletine, tocainide)
- Had received Lidoderm for LBP in the past
