title: Pyrithioxine and thiopronine: new penicillamine-like drugs in rheumatoid arthritis.
abstract: Two new SH-CH3-containing drugs have been studied as penicillamine-like agents. Pyrithioxine--retrospectively compared to a D-penicillamine series--was associated with fewer side effect-related withdrawals (14 vs 39) but with more non-responses and withdrawals for relapse. A review of the literature shows that thiopronine and D-penicillamine have a similar "score" of side effects and good responses. More extensively-controlled trials are needed for a better assessment of these new drugs.
