osteoarthritis is a debilitating disease that develops gradually. Pharmacological treatment is one of the ways to alleviate its symptoms and slow its progression. Cesanal reports estimate that the US population over 65 years of age will increase by 55% by the year 2030 (it will pass from 12.9% in 2005 to 20% in 2030). If the current incidence rates of Osteoarthritis and other chronic joint diseases are applied, the number of patients with these diseases will double in that period (Morbidity and Mortality Weckly report, 2004).
