Participant Flow

This was a single center, single dose, open-label, randomized, 2-part, 2-way crossover study. Bioequivalence (BE) between levocetirizine (levo) oral disintegrating tablet (ODT) and levocetirizine immediate release tablet (IRT) was evaluated in 72 healthy Japanese participants.

A total of 133 participants were screened, of them, 72 participants were randomized to receive study treatment. All participants except one participant randomized in Part 2 (Initial study) completed the study.

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention. A SAE is defined as any untoward medical occurrence that, at any dose may results in death or is life-threatening or requires inpatient hospitalization or results in persistent disability/incapacity or is a congenital anomaly/birth defect or any other situation according to medical or scientific judgment.

Blood samples were collected for the assessment of clinical chemistry parameters. Change from Baseline in calcium, cholesterol, chloride, glucose, high density lipids cholesterol, potassium, low density lipids cholesterol, sodium, phosphorus inorganic, triglycerides and urea/BUN levels were evaluated. The Baseline value was the latest pre-dose assessment with a non-missing value, including those from unscheduled visits.

Population: Safety Population. Only those participants with data available at the specified data points were analyzed.

Urine samples were collected to assess urine bilirubin, urine occult blood, urine glucose, urine ketones, urine protein and urine urobilinogen by dipstick test. The dipstick test gives results in a semi-quantitative manner, and results for urinalysis parameter of urine bilirubin, urine occult blood, urine glucose, urine ketones, urine protein and urine urobilinogen can be read as negative (-), trace and 1+ indicating proportional concentrations in the urine sample. Only categories with significant values have been presented.

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).

Urine samples were collected for the measurement of specific gravity. Urine specific gravity is a measure of the concentration of solutes in the urine and provides information on the kidney's ability to concentrate urine. The concentration of the excreted molecules determines the urine's specific gravity. The urinary specific gravity measurement is a routine part of urinalysis. The reference range is 1.002-1.030.
