The systemic and topical antiinflammatory activities of budesonide (B) were studied in rats and mice and compared with those of commercially available steroids. Betamethasone 17-valerate (BV) was used as the main reference compound, and fluosinolone acetonide (FA), hydrocortisone 17-butyrate (HB) and hydrocortisone 21-acetate (HA) were also used. B given systemically had stronger antiinflammatory effect than BV on carrageenin edema, cotton pellet granuloma, adjuvant arthritis, croton oil edema, PCA reaction, Arthus reaction, contact hypersensitivity and histamine or serotonin skin reaction. The potency of antiinflammatory activity of the 5 compounds in carrageenin edema, croton oil edema and contact hypersensitivity tests was in the order of FA, B, BV, HB and HA. B given locally also produced stronger antiinflammatory effects than BV on carrageenin edema, cotton pellet granuloma, croton oil edema and contact hypersensitivity. The order of potency of the 5 compounds in carrageenin edema, croton oil edema and contact hypersensitivity tests was the same as by systemic application. In general, the ratio of the dose required to cause atrophy of the thymus and adrenals to the dose required to produce the antiinflammatory effect was the greatest with B by both systemic and local application. The results suggest that B has a stronger antiinflammatory activity with fewer systemic side effects than conventional steroid compounds.
