Efficacy of carprofen, administered by different routes, was studied in experimental uveitis in dogs. Anterior chamber paracenteses was accomplished at two different moments (M0 and M1), with a five hour interval between them. At M0 and M1, 0.2mL of aqueous humor was collected and quantitation of total protein and prostaglandin E2 (PGE2) were determined. Four groups were formed (n=8), which received carprofen at the end of M0, by the following routes subcutaneous (GIm), subconjunctival (GII), and topical (GIII). A fourth group that received no treatment was instituted (Control). Conjunctival histopathology of the GII animals was performed. In all groups, values of protein and PGE2 significantly enhanced at M1; however, they did not significantly change among groups at M1. Inflammatory exudate of acute character and mild hemorrhage were seen at histopathology after carprofen administration. Carprofen was unable to inhibit PGE2 synthesis and the protein influx to the anterior chamber by any of the tested routes. However, the reduction of 44 percent in protein levels (topical) suggests that the agent can be used by this route as an adjuvant to control uveitis in dogs.
