title: [Anti-inflammatory action of 2-(2-fluoro-4-biphenylyl) propionic acid (flubiprofen].
abstract: 2-(2-fluoro-4-biphenylyl) propionic acid (flurbipofen, FP-70), a newly synthesized anti-inflammatory agent, was examined for its effects and then compared with the actions of other standard drugs. Inhibition of capillary permeability in mice: the activity of FP-70 was 7.8 times as potent as ibuprofen (IP), 61 times that of acetylsalicylic acid (AS), 5.7 times that of indomethacin (IM) and 25 times that of phenylbutazone (PB). Inhibition of carrageenin-induced edema in rat paw: the activity of FP-70 was 52 times as potent as IP, 250 times that of potent as AS, 14 times that of potent as IM and 110 times that of potent as PB. Inhibition of heat-induced coagulation of BSA: the activity of FP-70 showed the marked effects much the same as IP. In adrenalectomized rat, FP-70 was also effective. Inhibition of the ultra-violet erythema in guinea-pigs, the activity of FP-70 was 26 times as potent as IP, 790 times that of AS, 25 times that of IM and 68 times that of PB. Regarding the inhibition of CMC induced pouch in rats, the potency of FP-70 was to the same degree as that of predonisolone. In adjuvant induced arthritis in rats, FP-70 reduced and cured inflammatory syndromes and activity was the same or more effective than that of IM. From these results, FP-70 appears to be a most potent nonsteroidal anti-inflammatory agent.
