  Main functions:
  Diacerein works by blocking the actions of interleukin-1 beta, a protein involved in the inflammation and destruction of cartilage that play a role in the development of symptoms of degenerative joint diseases such as osteoarthritis. Due to its specific mode of action, which does not involve the inhibition of prostaglandin synthesis, diacerein has been shown to have anti-osteoarthritis and cartilage stimulating properties in vitro and animal models.
