assess duration of action, patients were challenged with allergen 16 hours after dosing. The percentage of eyes with zero itching in both studies was assessed at 3 minutes post allergen challenge. Results: The percentage of eyes with zero itch at the 3 minutes timepoint after the onset of action allergen challenge was 60.0% for OLO-treated eyes compared with 5.9% for vehicle-treated eyes (P , .0001, OLO vs vehicle). The percentage of eyes with zero itch at 3 minutes post allergen challenge following the 16-hour dosing was 59.8% for OLO-treated eyes compared with 22.0% for vehicle-treated eyes (P , .0001, OLO vs vehicle). Conclusions: In bilateral CAC studies, ocular itching was prevented in a higher percentage (P , .0001) of eyes treated with 0.2% olopatadine hydrochloride ophthalmic solution when compared with vehicle as early as 30 minutes and for at least 16 hours post dosing.
