GENERIC NAME: gold sodium thiomalate; aurothiomalate
BRAND NAME: Myochrysine
DRUG CLASS AND MECHANISM: Gold sodium thiomalate is a gold-containing chemical (salt) used in treating rheumatoid arthritis. Other gold salts available include injectable aurothioglucose (Solganal) and oral auranofin (Ridaura). It is not well understood exactly how gold salts work. In patients with inflammatory arthritis, such as adult and juvenile rheumatoid arthritis, gold salts decrease the inflammation of the joint lining and also prevent the inflammation from destroying the bone and cartilage surrounding the joint. Because they prevent destruction of joints (in contrast to antiinflammatory drugs that just treat symptoms and signs of arthritis but do not prevent the destruction) gold thiomalate is known as a disease-modifying antirheumatic drug (DMARD). Gold salts also may be referred to as second-line drugs because they are often considered when the arthritis persists in spite of the use of antiinflammatory drugs (NSAIDs and corticosteroids) which are not DMARDs. The term, second line, may be misleading, however, since anti-inflammatory drugs and DMARDs in general should be used together because of their different mechanisms of action and additive effects.
PRESCRIBED FOR: Gold sodium thiomalate is used in the treatment of active, progressive, or destructive forms of inflammatory arthritis, such as adult and juvenile rheumatoid arthritis. Off label (non-FDA approved) uses include Felty's Syndrome (a rare disorder that includes rheumatoid arthritis, a swollen spleen, and decreased numbers of white blood cells) and psoriatic arthritis.
