Elevation of BP, ie, supine systolic BP >145 mmHg and/or diastolic BP >92 mmHg, or heart rate >100 beats per minute at rest (Screening or Day -1). Readings that fall outside these ranges will be allowed to enter the study if they are health candidates at the Investigator's discretion. Have gastrointestinal malabsorption.
