Brief Summary:
Aim of this prospective, single-blind, randomized study was to compare the efficacy of the combination of celecoxib and pregabalin and celecoxib only monotherapy for treatment of chronic low-back pain.

Condition or disease Intervention/treatment Phase
Spinal Stenosis Lumbar Drug: Pregabalin 75mg Drug: Celebrex 200Mg Capsule Phase 4

Detailed Description:

The efficacy and safety of the association of celecoxib [a selective cyclooxygenase-2 (COX-2) inhibitor] and pregabalin (commonly used to control neuropathic pain), compared with monotherapy of each, were evaluated for the treatment of chronic low-back pain, a condition known to be due to neuropathic as well as nociceptive pain mechanisms.

We will compare the efficacy of the combination of a selective COX-2 inhibitor (celecoxib) and an antineuropathic drug, pregabalin, versus celecoxib only monotherapy, in the treatment of spinal stenosis.

Each treatment lasted 8 weeks

Primary outcome is mean pain reduction following different treatments regimes. Secondary outcomes are the changes of pain sensitivity, Oswestry disability index, adverse effects due to the treatments under study.
