Purpose:
To study the antiinflammatory capacity of topical pranoprofen in comparison with other ophthalmological nonsteroidal antiinflammatory drugs (diclofenac and flurbiprofen) in albino rabbits.
Methods:
We have produced an endotoxin-induced uveitis by intravitreal injection of 10 ng of Salmonella typhimurium endotoxin. We have used 48 albino rabbits (4 groups of 12 animals each), first group were control group (intravitreal saline solution), which were treated unilaterally every two hours with 2 drops of: Group II, pranoprofen (1 mg/ml). Group III, diclofenac (0.2 mg/ml). Group IV, flurbiprofen (0.3 mg/ml). We determined clinical signs of inflammation and protein concentration in the aqueous humor. The rabbits were sacrificed 24 hours after the endotoxin administration.
Results:
In all treated groups we observed a significant reduction (p<0.05) in all studied parameter as compared with control group, except for ciliar hyperemia. Different treatment groups did not show differences.
Conclusion:
The antiinflammatory capacity of pranoprofen is comparable to other NSAIDs derived from propionic acid such as flurbiprofen, obtaining a good control of endotoxin-induced uveitis.
