Inflammation is a process in which the body’s white blood cells and substances they produce would normally protect us from the infection of foreign organisms, such as bacteria and viruses.  However, with arthritis, the body’s immune system triggers an inflammatory response when there are no foreign invaders in your system to fight off.  And thus, the body’s normal protective immune system can cause damage onto itself, and damages its own tissues.

This medication works to reverse that, and to stop your body’s production of substances are causes the inflammation.
