Abstract

Lobenzarit disodium (LBZ) is an immunomodulator and antioxidative drug developed and used successfully in Japan for the treatment of rheumatoid arthritis (RA). Studies in animals and humans have shown striking differences between the pharmacological profile of LBZ and nonsteroidal antiinflammatory drugs commonly used in the treatment of RA. LBZ does not inhibit the biosynthesis of prostaglandins and leukotrienes and is ineffective on acute inflammatory reactions induced in animals. Therefore, its usefulness in RA is ascribed to immunopharmacological properties of the drug. Currently, evidence is available that B- and T-lymphocytes are targets of LBZ's actions which regulates the functions of these cells. LBZ reduces IgE titers in serum of sensitized mice by activating suppressor T-lymphocytes and inhibiting anaphylactic shock induced by ovalbumin. These results provide evidence in favor of the potential use of LBZ in the treatment of allergic diseases, which must be elucidated in controlled double-blind clinical trials. The suppressive effects of LBZ on the function of activated B cells as well as in the production of anti-DNA antibody have been reported. These findings suggest that LBZ may be effective in the treatment of othe...Continue Reading

Autoimmune hepatitis formerly called lupoid hepatitis, is a chronic, autoimmune disease of the liver that occurs when the body's immune system attacks liver cells causing the liver to be inflamed. Discover the latest research on autoimmune hepatitis here.

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
