Pharmacokinetics and pharmacodynamics of the novel H1-receptor antagonist emedastine in healthy volunteers

Objective: Emedastine is a novel H1-receptor antagonist with pre-clinically well-documented anti-allergic effects. Here, we set out to study the relationship between emedastine pharmacokinetics and the suppressive effect on histamine-induced wheals and flares, and to compare these effects to placebo and cetirizine.
