Ridaura: Full Drug Profile

Medically reviewed by Min Clinic Staff | Updated: January 2026

Ridaura - General Information

Ridaura is a organogold compound classified by the World Health Organization as an antirheumatic agent. Ridaura appears to induce heme oxygenase 1 (HO-1) mRNA. Heme oxygenase 1 is an inducible heme-degrading enzyme with anti-inflammatory properties.

 

Pharmacology of Ridaura

Ridaura 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).

 

Ridaura for patients

Unlike anti-inflammatory medications, Auranofin does not take effect immediately. In fact, you may have to wait for 3 to 6 months to get any benefit from Auranofin. Auranofin prevents or suppresses joint swelling, but does not cure rheumatoid arthritis.

 

Ridaura Interactions

Auranofin should be avoided by patients with a history of serious reaction to any gold medication, including Solganal and Myochrysine. Auranofin should not be used together with penicillamine (Depen, Cuprimine), another arthritis medication. It should also be avoided in patients with blood, liver or kidney diseases, recent radiation treatment, or uncontrolled diabetes. Patients should report to their practitioners any new rashes, itching, mouth sores, or unusual taste while taking auranofin. Gold is excreted slowly from the body. Safety and effectiveness in children has not been established.
