[Controlled clinical trial of parsalmide]

A double-blind, between-patients comparison between parsalmide (a new drug) and phenylbutazone in 55 patients with postraumatic joint and muscle pain showed that the two compounds possessed about the same anti-inflammatory and analgesic activity, though parsalmide gave greater relief of pain and local swelling. Tolerance was excellent for both drugs. Slight gastric disturbances noted in 2 subjects with both compounds were easily corrected by symptomatic management.
