• To determine the relative bioavailability of a single oral dose of cetirizine HCl Gummy 10 mg administered under fasted conditions with and without water in healthy adult male and female subjects;
• To determine the relative bioavailability of a single oral dose of cetirizine HCl Gummy 10 mg administered under fasted conditions and chewed or swallowed whole in healthy adult male and female subjects.

   3. Postmenopausal (no menstruation for a minimum of 12 months and confirmed by FSH and estradiol at Screening);

5. Medically healthy based on medical history, vital sign measurements, clinical laboratory test results, and physical examination;

6. Non-smokers (including nicotine-containing products) for at least 6 continuous months prior to the first dose.

7. Be willing and able to consume all contents of the standardized high calorie, high fat breakfast within 30 minutes prior to dosing.

2. Life-time history and/or recent evidence of alcohol or drug/substance abuse disorder;
3. Subjects with history of hypersensitivity to cetirizine or hydroxyzine, or any component of the test and reference formulations;
4. Subjects who test positive at Screening for human immunodeficiency virus (HIV), Hepatitis B surface antigen (HBsAg), or Hepatitis C virus (HCV) antibody;
5. Subjects who test positive at Screening or at Check-in for alcohol and/or drugs of abuse;
6. Subjects who donated ≥ 500 mL of blood within 56 days prior to the first dose of study drug or ≥ 50 mL and ≤ 499 mL of blood within 30 days or plasma (e.g. plasmapheresis) within 14 days prior to the first dose of study drug;
