Tác dụng
Description: Penicillamine in rheumatoid arthritis has an unknown mechanism but, it suppresses the disease activity. It also decreases circulating IgM rheumatoid factor and T-cell activity. It interacts w/ cystine to form a more soluble complex thereby reducing urinary concentration of cystine and preventing renal calculi development. It is a chelating agent which aids the removal of heavy-metal ions including copper, lead, arsenic and mercury from the body by forming complexes that are readily excreted by the kidney.
Onset: Rheumatoid arthritis: 2-3 mth; Wilson’s disease: 1-3 mth.
Absorption: Rapidly but incompletely absorbed from the GI tract. Decreased absorption w/ food. Time to peak plasma concentration: W/in 1-3 hr.
Distribution: Plasma protein binding: >80% mainly to albumin; binds also to α-globulins, ceruloplasmin, erythrocytes, macrophages.
Metabolism: Metabolised in the liver to S-methyl-D-penicillamine.
Excretion: Via urine (approx 80%, mainly as mixed disulfides; some as penicillamine copper complex and S-methyl-D-penicillamine). Elimination half-life: 1.7-7 hr.
