[Acadione, a new long-term treatment of rheumatoid polyarthritis].

This article summarizes the authors' experience and data from the literature regarding acadione, a medication like D-penicillamine with a thiol radical, in the treatment of rheumatoid arthritis. Two control studies versus placebo and two control trial versus D-penicillamine prove the effectiveness of the treatment and demonstrate a similar activity between 1 g of acadione and 600 mg of D-penicillamine. The side-effects of acadione are similar of those of D-penicillamine, essentially rash, toxic dermatitis, agueusia, proteinuria, which disappear upon discontinuation of the treatment. The fact that the patient exhibited a side effect with D-penicillamine, increases, the risk with acadione, but this is not systematic, which is the main advantage of this product.
