Efficacy Safety of a Combination Thiocolchicoside+Ketoprofen Compared to Thiocolchicoside Twice a Day for 7 Days in Patients Suffering From Acute Non Specific Low Back Pain

Study Overview
=================
Brief Summary
-----------------
Primary Objective : To demonstrate the superiority of the oral fixed - combination of a muscle relaxant, thiocolchicoside (TCC) to a non steroidal anti-inflammatory drug, ketoprofen, over oral TCC, on average pain within the last 24 hours in adults suffering from acute non specific low back pain with an episode of recent onset Secondary Objective : To compare the safety of the oral combination to that of oral TCC alone

Eligibility Criteria
-----------------
List of Inclusion and Exclusion criteria : Inclusion Criteria: Non specific low back pain with an acute episode of recent onset (<48 hours) defined by average pain within the last 24 hours equal or more than 50 mm on the Visual Analogue Scale (VAS) Low back pain of diagnosis category 1 (low back pain radiating no farther than the intergluteal fold) or 2 (low back pain radiating no farther than the knee), as defined by the International Paris Task Force on Back Pain Exclusion Criteria: Exclusion criteria related to study methodology: Low back pain due to vertebral collapse or of no mechanical origin (suspected by history taking and physical examination), such as neoplasm, infection or inflammatory disorders, Low back pain of diagnosis category 3 (low back pain radiating beyond the knee, with no neurologic signs) or 4 (low back pain radiating to a precise and entire leg dermatome, with or without neurologic signs), as defined by the International Paris Task Force on Back Pain History of inflammatory arthritis of large joints, History of seizure disorders, History of malignant tumour, Treatment with steroidal agents (including aspirin) during the two days prior to prospective inclusion, prolonged used of corticosteroids, Treatment with NSAIDs or muscle relaxant or opioid analgesics within 3 days of admission, Psychiatric or mental diseases, Immunosuppression, HIV, Inclusion in another study in the past six months or previous inclusion in this study, History of alcohol, drugs or narcotics abuse Recent history of violent trauma, Constant progressive, non mechanical pain (no relief with bed rest), Thoracic pain, Patient systemically unwell, Unexplained weight loss, Widespread neurological symptoms (including cauda equine syndrome), Structural deformity Fever, Clinical significant renal dysfunction defined by Creatinine > 1.5 UNL, Clinically significant hepatic dysfunction defined by: Total Bilirubin > 2 UNL SGOT (AST) > 1.5 UNL SGPT (ALAT) > 1.5 UNL Alkaline Phosphatase > 1.5 UNL Patients who have received other therapy (physiotherapy, physical manipulations, invasive intervention, acupuncture therapy...) within the last 48 hours. Exclusion criteria related to trial drugs: Pregnancy, breast feeding or women of childbearing potential not using efficient contraception. Patient with Intra Uterine Device should use another form of contraception as the efficacy of the IUD may be reduced by ketoprofen. Exclusion criteria related to thiocolchicoside: Known or suspected hypersensitivity to thiocolchicoside Exclusion criteria related to ketoprofen: Uncontrolled heart failure, Arterial Hypertension (SBP>140 mmHg or DBP >90 mmHg), Stroke or myocardial infarction in the past, Myopathy Myasthenia, History of active peptic ulcer or gastrointestinal (GI) bleeding, history of gastric pain with NSAIDs, History of NSAID/aspirin-induced asthma, Known or suspected hypersensitivity to ketoprofen.
