Purpose: We compared the efficacy of a new nonsteroidal antiinflammatory drug (NSAID) eye drop, 0.1% bromfenac sodium (Bromfenac), with that of an antiallergic agent, 0.1% pemirolast potassium (Pemirolast), in the treatment of seasonal allergic conjunctivitis in Japanese patients.
Methods: Twenty-two subjects with seasonal allergic conjunctivitis were enrolled in the study. One eye was treated with Bromfenac eye drops and the contralateral eye was treated with Pemirolast eye drops for 1 week. Subjective ocular symptoms and objective ocular signs evaluated by slit-lamp examination were scored and recorded before and after treatment.
Results: Both drugs significantly decreased ocular signs after 1 week, but not symptoms. No significant differences in subjective symptoms or objective signs were observed between the two drugs. Ten patients (45.5%) selected Bromfenac as more effective, nine patients (40.9%) selected Pemirolast, and three patients found no difference in efficacy between the two drugs.
Conclusion: Bromfenac sodium is as safe and effective for the treatment of allergic conjunctivitis as pemirolast potassium.
