[New basic preparations with prolonged action in the treatment of rheumatoid arthritis].

A long-term comparative study of the classic basic drug-d-Penicillamin and 2 new sulfa drugs: sulfasalazin and salazopyridazin used for the first time in rheumatology, was conducted. Both drugs were shown to produce a "basic" effect in rheumatoid arthritis and to exceed d-Penicillamin in their therapeutic action. Better results were obtained with salazopyridazin. The tolerance to the new antirheumatic sulfa drugs was quite satisfactory; no severe side-effects were noted. Both drugs extend the potentialities of antirheumatoid therapy of prolonged action and warrant further use and study.
