Appropriateness of clinical criteria for the use of symptomatic slow-acting drug for osteoarthritis (SYSADOA). A Delphi method consensus initiative among experts in Italy
OsteoArthritis (OA) is a theme currently representing an emerging topic for its increasing incidence. It is well known that it is a chronic disease that could lead to important long-lasting disability; this generates increasing costs for the health care system. OA treatment options vary: localization, aetiology, grading and symptomatology should be considered before choosing the most adequate therapy. Currently, a modern approach to managing OA involves SYmptomatic Slow Acting Drugs in Osteo-Arthritis (SYSADOAs). However, while all preparations may claim to deliver a therapeutic level of glucosamine or chondroitin, not all of them are supported by clinical evidence. Recently the European Society for Clinical and Economic aspects of Osteoporosis, Osteoarthritis and musculoskeletal diseases (ESCEO), produced an evidenced based document providing practitioners with the latest clinical and economic informations, thereby allowing them to optimize the management of knee OA. According to this report, only crystalline glucosamine sulphate and the pharmaceutical-grade chondroitin sulphate are considered as effective in the first line approach to treating knee OA as an alternative drug to acetaminophen. However, some OA guidelines do not agree are not concordant in recommending the use of SYSADOA, perhaps because they are generally considered as a class and distinctions among formulations aren't made
