A follicle stimulating hormone (FSH) level will be performed to confirm a post-menopausal status. For this study, FSH levels of \> 40 MlU/ml is confirmatory. For females on hormone replacement therapy (HRT) and whose menopausal status is in doubt, HRT should be discontinued for 2 weeks and then the subject rescreened, as HRT can suppress FSH.

- Body weight ≥ 50 kg for men and ≥ 45 kg for women and BMI within the range 18.5-31.0 kg/m2 (inclusive).
- Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.
- AST, ALT, alkaline phosphatase and bilirubin ≤ 1.5xULN (isolated bilirubin \>1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin \<35%). A single repeat is allowed for eligibility determination.
Exclusion
- A positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody result within 3 months of screening
- A positive test for HIV antibody.
- A positive pre-study drug/alcohol screen. A minimum list of drugs that will be screened for include amphetamines, barbiturates, cocaine, opiates, cannabinoids, and benzodiazepines.

- The subject has participated in a clinical trial and has received an investigational product within the following time period prior to the first dosing day in the current study: 30 days, 5 half-lives or twice the duration of the biological effect of the investigational product (whichever is longer).
- Use of prescription or non-prescription drugs, including vitamins, herbal and dietary supplements (including St John's Wort) within 7 days (or 14 days if the drug is a potential enzyme inducer) or 5 half-lives (whichever is longer) prior to the first dose of study medication, unless in the opinion of the Investigator and GSK Medical Monitor the medication will not interfere with the study procedures or compromise subject safety.

- Subjects with a pre-existing condition interfering with normal gastrointestinal anatomy or motility, hepatic and/or renal function, that could interfere with the absorption, metabolism, and/or excretion of the study drugs. Subjects with a history of cholecystectomy, peptic ulceration, inflammatory bowel disease or pancreatitis should be excluded.
- Serum creatinine values greater than the upper limit of normal. A single repeat is allowed for eligibility determination.
- The subject's systolic blood pressure is outside the range of 90-140mmHg, or diastolic blood pressure is outside the range of 45-90mmHg or heart rate is outside the range of 50-100bpm for female subjects or 45-100bpm for male subjects.
