Significant: Gold toxicity (e.g. decreased haemoglobin, leukocytes [WBC <4000/mm³], granulocytes [<1500/mm³], or decreased platelets [<150,000/mm³]), nephrotic syndrome or glomerulitis with proteinuria and haematuria, pruritus, rash, stomatitis, persistent diarrhoea/loose stools. Rarely, gold bronchitis, interstitial pneumonitis, fibrosis; ulcerative enterocolitis, cholestatic jaundice.

PO: C

Avoid exposure to sunlight or artificial UV light during treatment.

Monitor CBC with differential, platelet count, urinalysis (baseline and monthly during treatment); renal function tests and LFTs (baseline). Assess for signs and symptoms of gastrointestinal bleeding, skin rash, pruritus, bruising, oral ulceration, stomatitis, or metallic taste.

Description:
Mechanism of Action: Auranofin, an orally active gold compound, is a disease-modifying anti-rheumatic drug (DMARD) that exhibits anti-inflammatory, antiarthritic, and immunomodulating properties. Its exact mechanism is not fully understood; however, it is presumed to act primarily through immunomodulation and by reducing lysosomal enzyme release. Gold salts decrease antibody and cytokine release, reduce cellular proliferation, and inhibit collagenase.
Onset: Delayed (as long as 6 months).
Duration: Prolonged.
Pharmacokinetics:
Absorption: Incompletely absorbed from the gastrointestinal tract. Time to peak plasma concentration: Approx 2 hours.
Distribution: Penetrates into synovial fluid. Plasma protein binding: 60%.
Metabolism: Rapidly metabolised.
Excretion: Via urine (approx 60% of the absorbed gold); faeces. Elimination half-life: 21-31 days.
