Brief Summary  
This study is designed as a Prospective, Randomized, Parallel Group, Open Label, Multi-centric, Active Controlled Study to Evaluate the Efficacy and Safety of fixed dose combination of Etoricoxib(60mg) +Thiocolchicoside (4mg) vs Chlorzoxazone(500mg) +Diclofenac(50mg) +Paracetamol(325mg) in Low Back Pain. The Primary objective is to evaluate the efficacy of fixed dose combination of Etoricoxib(60mg) +Thiocolchicoside (4mg) vs Chlorzoxazone(500mg) +Diclofenac(50mg) +Paracetamol(325mg) in low back pain post 4 weeks of treatment.

Subjects will be recruited from out-patient departments of study sites. On the randomization visit of Day 0 a written informed consent will be obtained from subjects fulfilling the inclusion/exclusion criteria described in the study protocol. In cases of subjects who have taken NSAIDs or muscle relaxants during the last 3 days a washout period (minimum 2 days for all medications that have an elimination half-life of less than 10 hours or at least 5 times the elimination half-life for medications with longer half-lives1 ). An initial or baseline pain assessment (the day of randomization prior to dosing) will be recorded. Subjects will undergo a physical examination. Subjects will be instructed to fill the Wong Bakers Face Pain Scale and Oswestry disability index (ODI) Subjects will be randomized to one of the two arms as per predefined randomization list. Subject diary will be provided to all enrolled subjects. Baseline laboratory investigations (Complete Hemogram, Liver function and renal function test) will be performed. Subjects will be contacted telephonically at Day 14 and enquired about drug compliance, relief of low back pain and occurrence of any adverse event. At end of study visit subjects will be evaluated physically at site. A complete physical examination will be carried out (Finger to floor distance/ Lasegue’s manuevre). Subjects will be guided to fill the Wong Bakers Face Pain Scale and Oswestry disability index (ODI) for study end assessment. Subject diary will be reviewed. IP compliance will be checked and adverse events experienced would be evaluated. End of study laboratory investigations will be carried out.
