Clinical Pharmacology:
12 clinical pharmacology 12.1 mechanism of action zerviate, an antihistamine, is a histamine-1 (h1) receptor antagonist. the antihistaminic activity of cetirizine has been documented in a variety of animal and human models. in vivo and ex vivo animal models have shown negligible anticholinergic and antiserotonergic activity. in vitro receptor binding studies have shown no measurable affinity for other than h1 receptors. 12.3 pharmacokinetics in healthy subjects, bilateral topical ocular dosing of one drop of zerviate⢠(cetirizine ophthalmic solution) 0.24% 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.

Clinical Studies:
14 clinical studies the efficacy of zerviate was established in three randomized, double-masked, placebo-controlled, 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. table 1 displays data from the mean ocular itching severity scores after ocular administration of an antigen using the cac model. a one unit difference compared to vehicle is considered a clinically meaningful change in the ocular itching severity score. patients treated with zerviate demonstrated statistically and clinically significantly less ocular itching compared to vehicle at 15 minutes and 8 hours after treatment. table 1 itching scores in the
