Abstract

Purpose: To study the antiinflammatory effect of topical pranoprofen on the lipoxygenase metabolism of the arachidonic acid in albino rabbits.

Methods: Endotoxin-induced uveitis (EIU) was produced in albino rabbits by intravitreal injection in the right eye with 10 microg of Salmonella typhymurium lipopolysacharide A in 5 microl saline solution. We have used 5 groups of 12 animals each. Control group (G-I) was injected with 5 microl of saline solution and 5 microl of ET solution were injected in the remaining groups. Groups III, IV and V were treated with topical pranoprofen 2 hours before intravitreal injection, immediately after and every 6, 4 and 2 hours respectively. The animals were sacrificed 24 hours after the ET administration. Cellular and B4 leukotrien concentration in the aqueous humour was determined.

Results: The groups treated with pranoprofen showed a significant decrease in the cellular concentration in relation to the group of endotoxin (G-II). We did not observe any difference in the B4 leukotriene concentration between ET group and topical pranoprofen groups.

Conclusion: Topical pranoprofen has not increased the lipoxygenase metabolism of the arachidonic acid.
