Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   Yes
Criteria

Inclusion criteria:

Subjects must meet the following inclusion criteria at Visit 1, Visit 2 and Visit 3.

Inclusion criteria for Group A (overweight postmenopausal females with high-normal blood pressure/ mild Stage I hypertension)

  1. Non-smoking female outpatients diagnosed as postmenopausal based on age (48 - 65 years) and self-reported absence of menstrual periods for at least one year.
  2. Mean blood pressure between 130 - 149 mm Hg systolic and/or 85 - 94 mm Hg diastolic

    • When systolic blood pressure and diastolic blood pressure fall into different categories (high normal versus mild stage I hypertension), the higher category should be selected to classify or group the subject.

  3. Body mass index greater than or equal to 26 but less than or equal to 41 kg/m2
  4. Subjects who agree not to alter their diet or exercise routine during the study and comply with study specific restrictions 24 hours prior to the next scheduled study visit
  5. Subjects who have read, signed and received a copy of the informed consent form prior to the initiation of any study procedures and who agree to participate in all aspects of the study

Exclusion Criteria:

  • 1. Non-smoking female outpatients diagnosed as postmenopausal based on age (48 - 65 years) and self-reported absence of menstrual periods for at least one year.

    2. Mean blood pressure between 90 - 129 mm Hg systolic and/or 50 - 84 mm Hg diastolic.

    3. Body mass index greater than or equal to 26 but less than or equal to 41 kg/m2
