Utilizing 3 different methods for analyzing the results, a single dose double-blind crossover study of the effectiveness of 5 analgesics and placebo against the pain of rheumatoid synovitis in 30 subjects showed all active drugs superior to placebo by 1 analysis; aspirin, codeine and acetaminophen superior to both placebo and propoxyphene by a second; and aspirin alone superior to placebo and propoxyphene by a third. More side effects were reported from pentazocine than from other agents.
