Other possible mechanisms includeinhibition of phagocytic activity of macrophages and polymorphonuclear leukocytes,alteration of biosynthesis of collagen, and alteration of the immune response. Gold willnot reverse damage to joints caused by disease. Approximately 25% of an oral dose isabsorbed. Plasma t1/2 of auranofin gold: 26 days. Onset: 3-4 months(up to 6 months in certain clients).
