The effects of topical S(+)-ibuprofen on interleukin-1 induced ocular inflammation in a rabbit model.

Topical non-steroidal anti-inflammatory drugs may serve as an alternative or adjunct to topical corticosteroid therapy for iritis. We have tested the efficacy of topically given S(+)-ibuprofen in a rabbit model of uveitis secondary to the intravitreal injection of human recombinant interleukin 1-alpha. Topically administered S(+)-ibuprofen was found to inhibit increased vascular permeability associated with this model. These results with topical S(+)-ibuprofen compare favorably to the results seen with topical prednisolone and are significantly superior to the results seen with topical flurbiprofen. Topical S(+)-ibuprofen did not significantly reduce the cellular infiltration associated with interleukin-1 induced inflammation. These findings suggest a potential role for topical S(+)-ibuprofen in the treatment of ocular inflammation and, in this animal model, it appears to be superior to an alternative non-steroidal compound, but further studies are indicated to assess its activity in alternate models of ocular inflammation.
