[Comparative effectiveness of the basic drugs used in rheumatoid arthritis (long-term randomized study)].

Study of the comparative efficacy of the basic slow-acting drugs for the treatment of rheumatoid arthritis permits considering randomization as necessary for obtaining objective data. It has been established that gold salts (chrisanol and myochrysin) are the most efficacious drugs for the treatment of RA. D-Penicillamine and delagil, in particular, are less efficacious. Administration of levamisole is rather dangerous because of the frequency and intensity of side effects.
