To Test Bioequivalence Between Two Tablet Formulations in the Treatment of Allergy

A Randomized, Open-Label, Single-Dose, Three-Period Crossover Bioequivalence Study to Compare an Orodispersible Tablet (ODT) Formulation of Cetirizine HCl 10 mg Taken With and Without Water Compared With a Standard Marketed 10 mg Tablet Taken With Water

This study is designed to assess bioequivalence between two products used for treatment of allergy.

This study is designed to evaluate if a test formulation of cetirizine 10 mg orodispersible tablet (ODT) taken with and without water is bioequivalent to a marketed reference formulation of cetirizine 10 mg tablet (Benadryl One A Day, McNeil Products Ltd, UK) taken with water. This study will also evaluate the tolerability of test and reference formulations.
