简要总结
The purpose of this study is to evaluate the pain relief effect of Co-administration of Diacerein with Celecoxib in patients with knee osteoarthritis compared with single administration of each drug.
详细描述
A large epidemiological study in Europe reported that over four-thirds of patients with osteoarthritis received combination therapy with two or more drugs. Approximately 1.5% of patients with osteoarthritis using three or more drugs are using COX-2(Cyclo-oxygenase-2) inhibitors and SYSADOA(Symptomatic slow acting drug), And it has been investigated that much more patients are using the two classes of drugs when the range is extended to other oral NSAIDs other than COX-2 inhibitors. Therefore, considering the characteristics of patients with osteoarthritis, such as basal disease and treatment effects on each type of drug, it is important to find the optimal combination of drugs for each patient characteristics.
There is a previous study using osteoarthritis rat model as a biological basis of diacerein and celecoxib administration. Previous studies have shown that the combined use of Diacerein and Celecoxib improves osteoarthritis.
The purpose of this study is to evaluate the pain relief effect of Co-administration of Diacerein with Celecoxib in patients with knee osteoarthritis compared with single administration of each drug.
