COMPLETE DESCRIPTION Field of the invention The present invention relates to the pharmaceutical composition comprising the combination of lornoxicam and diacerein, which provide the patients a better and faster relief from osteoarthritic pain. The composition can be applied to symptomatic treatments of various febrile illnesses, various arthritises and inflammatory rheumatic diseases, soft tissue rheumatisms, neuralgia, arthralgia and pains, wounds relevant to degenerative diseases of spines, or postoperative pains. Backaround of the invention Osteoarthritis is the most common joint disorder in world. It is one of the most frequent causes of pain, loss of function and disability in adults. Till recently osteoarthritis was classified as a mechanical wear and tear disorder of articular cartilage for which only pain modifying therapies such as analgesics were prescribed with little scientific attention focused on modification of course of disease leading to musculoskeletal disability and affecting quality of life. The current treatment of osteoarthritis is primarily focused on symptomatic relief by use of rapid action drugs (analgesics and NSAIDS) and newer cycloxygenase (COX-2) specific inhibitors. Analgesics/NSAIDS use increases the risk of upper gastrointestinal adverse effects and does not affect the underlying pathogenesis of articular diseases, thus have minimal role in modifying disease course and improving quality of life. Although COX -2 inhibitors have reduced incidence of gastrointestinal adverse events but may have significant renal and cardiovascular toxicities. Hence, there is continuous search of new and better drug for OA. Recently there has been Increase in the use of symptomatic slow acting drugs /chondroprotective drugs /connective tissue structure modifying agents (e.g. chemically modified tetracyclines, glucosamine or chondritin sulphate and diacetylrhein/diacerein. These drugs have gradual onset of action (4-6 weel
