Indication |
Used in the treatment of active, progressive or destructive forms of inflammatory arthritis, such as adult rheumatoid arthritis. |
Pharmacodynamics |
Auranofin is a gold salt used in treating inflammatory
arthritis. Gold salts are called second-line drugs because they are
often considered when the arthritis progresses in spite of
antiinflammatory drugs (NSAIDs and corticosteroids). |
Mechanism of action |
Exactly how auranofin works is not well understood. It may act as
an inhibitor of kappab kinase and thioredoxin reductase which would lead
to a decreased immune response and decreased free radical production,
respectively. In patients with inflammatory arthritis, such as adult and
juvenile rheumatoid arthritis, gold salts can decrease the inflammation
of the joint lining. This effect can prevent destruction of bone and
cartilage. |
