ZERVIATE

In healthy subjects, bilateral topical ocular dosing of one drop of ZERVIATE ® resulted in a mean cetirizine plasma C max of 1.7 ng/mL following a single dose and 3.1 ng/mL after twice-daily dosing for one week. The observed mean terminal half-life of cetirizine was 8.6 hours following a single dose and 8.2 hours after twice-daily dosing of ZERVIATE ® for one week.

The efficacy of ZERVIATE ® (cetirizine ophthalmic solution) 0.24% was established in three randomized, double-masked, placebocontrolled, conjunctival allergen challenge (CAC) clinical trials in patients with a history of allergic conjunctivitis. Onset and duration of action were evaluated in two of these trials in which patients were randomized to receive ZERVIATE ® or vehicle ophthalmic solutions. Patients were evaluated with an ocular itching severity score ranging from 0 (no itching) to 4 (incapacitating itch) at several time points after CAC administration.

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trial of a drug cannot be directly compared to rates in clinical trials of another drug and may not reflect the rates in practice. In seven clinical trials, patients with allergic conjunctivitis or those at a risk of developing allergic conjunctivitis received one drop of either cetirizine (N=511) or vehicle (N=329) in one or both eyes. The most commonly reported adverse reactio...
