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.

Maximum Observed Plasma Concentration
Maximum Observed Plasma Concentration (Cmax), which is the maximum (peak) concentration (amount of drug) measurable in blood plasma after a dose is administered, measured in nanograms/milliliter (ng/mL)
Time frame: During 32 hours post-dose
Bioavailability [AUC(0-t)]
Bioavailability \[AUC(0-t)\] is a measure of how much of the drug reaches the person's bloodstream within a given period of time for the body to use. The extent of product bioavailability is estimated by the area under the blood concentration vs time curve. The Area Under the Curve (AUC) is calculated by plotting the drug's blood levels on a graph at different times during the set period. The area under this curve reflects the amount of drug exposure in the set time period, calculated as hour \* nanograms (ng) per milliliter (mL).
Time frame: During 32 hours post-dose
Bioavailability Extrapolated to Infinity [AUC (0-∞)]
Bioavailability Extrapolated to Infinity \[AUC (0-∞)\] is a calculated measure of how much of the drug will ever reach the person's bloodstream for the body to use. AUC (0-∞) stands for the area under the plasma concentration versus time curve from time zero (pre-dose) to extrapolated infinite time (forever). It is obtained from calculating AUC (0-t) plus AUC (t-∞).
Time frame: 32 hours post-dose
Time of Maximum Concentration
The time at which maximum concentration is reached (Tmax)
Time frame: During 32 hours post-dose
Terminal Elimination Rate Constant
The Terminal Elimination Rate Constant (Lamda z) is the time required to eliminate half the administered dose
Time frame: During 32 hours post-dose

Terminal Phase Plasma Half-Life
Terminal phase plasma half-life (t ½) is the time required to divide the plasma concentration by two after reaching pseudo-equilibrium, rather than the time required to eliminate half the administered dose.
Time frame: During 32 hours post-dose
Area under the Curve to the Tmax of the Reference Products
Area under the plasma concentration versus time curve to the time of the maximum concentration of the reference products (AUCReftmax)
Time frame: During 32 hours post-dose
Relative percentage of AUCT with respect to AUC∞ (AUCT/∞)
AUCT is the area under the plasma concentration verses time curve from start of drug administration until the time of the last measurable plasma concentration. AUC∞ is the area under the plasma concentration versus time curve from start of drug administration until extrapolated infinite time. AUCT/ AUC∞ is an inversed measure of how large the extrapolated area under the curve is.
Time frame: During 32 hours post-dose
Mean Residence Time
The average amount of time a particle (e.g., a drug substance molecule) remains in a compartment or system.
Time frame: During 32 hours post-dose
