Bioequivalence Study Between Levocetirizine Oral Disintegrating Tablet (ODT) and Levocetirizine Immediate Release Tablet (IRT)

Study Overview
=================
Brief Summary
-----------------
This study will be an open-label, randomized 2-way cross-over study to evaluate bioequivalence study between levocetirizine ODT and levocetirizine IRT in healthy Japanese male subjects. Approximately 48 subjects will participate in this study to receive a single dose treatments of levocetirizine ODT 5 milligram (mg) or levocetirizine IRT 5 mg. In Part 1, subjects will randomized in 1:1 ratio (12 in each Period) in Period 1 and 2 to receive single dose of levocetirizine ODT 5 mg with water or single dose levocetirizine IRT 5 mg with water in fasted state. In this part, comparison of bioavailability of levocetirizine ODT and levocetirizine IRT when taken with water in the fasted state will be assessed. In Part 2, subjects will be randomized in 1:1 ratio (12 in each Period) in Period 1 and 2 to receive single dose levocetirizine ODT 5 mg without water or single dose levocetirizine IRT 5 mg with water in fasted state. In this part, comparison of bioavailability of levocetirizine ODT without water and levocetirizine IRT with water in the fasted state will be assessed. There will be at least a 5-day wash out period between the intervention periods. The duration of each subject's participation in each part will be approximately 7 weeks from screening to follow-up.

| Part 1: Urine Potential of Hydrogen (pH) | Urine samples were collected for the measurement of urine pH. Urine pH is an acid-base measurement. pH is measured on a numeric scale ranging from 0 to 14; values on the scale refer to the degree of alkalinity or acidity. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic. Normal urine has a slightly acid pH (5.0 - 6.0). | Pre-dose (Day 1) and 48 hours post-dose |
