Double-blind study with liposteroid in rheumatoid arthritis.

A multicentre double-blind comparative trial was performed in 138 patients with rheumatoid arthritis (RA) after biweekly intravenous or intramuscular injections of liposteroid (containing 2.5 mg of dexamethasone), which had been developed as a drug for targeting therapy of RA, and Decadron (containing 3.3 mg of dexamethasone) as a reference drug. The results showed a tendency to a significantly higher rate of improvement with lower frequency of side-effects in the liposteroid group than in the Decadron group. This study indicates that liposteroid is more useful for RA and that the separation of the efficacy and side-effects of steroids could be clinically confirmed to some extent.
