How do other rheumatologic drugs work?

Other rheumatologic drugs are medications that are not categorized into any of the specific classes of rheumatologic drugs. Each of the other rheumatologic drugs works in unique ways and they are used in the treatment of conditions that include autoimmune and arthritic diseases.

The medications that are grouped under other rheumatologic drugs include:

  • Belimumab: Belimumab is a biological drug used to treat different forms of lupus, a group of inflammatory autoimmune diseases. Belimumab controls inflammation by inhibiting the activity of B-lymphocyte stimulator (BLyS), a protein that stimulates immature B-cells to become mature plasma B cells that produce antibodies.
  • Collagenase clostridium histolyticum: Collagenase clostridium histolyticum is a medication used to treat Dupuytren’s and Peyronie’s diseases, which are caused by tissue hardening from the buildup of collagen, a structural protein in connective tissue. Collagenase clostridium histolyticum is an enzyme that breaks up collagen.
  • Pegloticase: Pegloticase is a medication used to treat gout, a painful condition caused by excess uric acid in the blood getting deposited as crystals in the joints. Pegloticase is an enzyme that converts uric acid into a more soluble compound that is easier to excrete.
  • Hyaluronic acid and derivatives: Hyaluronic acid is a naturally occurring substance in the body that provides moisture and lubrication throughout the body. Hyaluronic acid and its derivatives are purified extracts from animal tissue or bacteria, injected into the knee to lubricate the joint and relieve pain from osteoarthritis.
  • Sodium hyaluronate: Sodium hyaluronate is a sodium salt of hyaluronic acid and works as a lubricant in the knee joint and relieves osteoarthritic pain. Sodium hyaluronate is also used in the eye during certain eye procedures and in the management of wounds and ulcers.


The term arthritis refers to stiffness in the joints. See Answer

    • Cellulite, fat deposits under the skin
  • Pegloticase
    • Gout, a painful condition caused by excessive uric acid in the blood which gets deposited as crystals in joints
  • Hyaluronic acid and derivatives
    • Osteoarthritis of the knee is an age-related degenerative disease caused by the wearing out of cartilage in the knee
    • Emphysema (lung disease) due to alpha1-antitrypsin deficiency (orphan designation), an inherited disorder
