Excluding oral contraceptives (combination oestrogen/progesterone pills), injectable progesterone or subdermal implants.

18. Is not permitted to use strong inhibitors and/or inducers of CYP450 within 21 days prior to the planned first drug administration

19. Subjects have veins unsuitable for intravenous puncture or cannulation on either arm (e.g. veins that are difficult to locate, access or puncture veins with a tendency to rupture during or after puncture)

20. Blood ALT, AST and bilirubin should be in the normal range at screening and on admission

21. Donation of more than 500 mL of blood within 90 days prior to drug administration
