GENERIC NAME: thalidomide

BRAND NAME: Thalomid

DRUG CLASS AND MECHANISM: Thalidomide is an oral medication used for treating the skin conditions of leprosy, a disease caused by a parasite, Mycobacterium leprae. The mechanism of action of thalidomide is not well understood. The immune system reaction to Mycobacterium leprae plays an important role in producing the skin manifestations of leprosy. Scientists believe that thalidomide modifies the reaction of the immune system to Mycobacterium leprae and thereby suppresses the skin reaction. Thalidomide also is being evaluated as a treatment for HIV. Thalidomide was approved by the FDA in July, 1998.
