- Negative screen for alcohol and drugs of abuse at screening and at admission to each inpatient period,
- Non-smokers or ex-smokers for at least 3 months,
- Able to participate, and willing to give written informed consent and comply with the study restrictions,
- Able to swallow a high number of capsules within a short time frame,
- If female:
- Was not of childbearing potential by reason of surgery or, if of childbearing potential, used an effective non-hormonal method of contraception (intrauterine device or intrauterine system; condom or occlusive cap \[diaphragm or cervical or vault caps\] with spermicidal foam or gel or film or cream or suppository; true abstinence; or vasectomized male partner, provided that he was the sole partner of that subject) for the entire duration of the study,
- Negative serum pregnancy test at screening and a negative urine pregnancy test at admission to each inpatient period.
You may not qualify if:
- Any clinically relevant history or presence of respiratory, gastrointestinal, renal, hepatic, haematological, lymphatic, neurological, cardiovascular, psychiatric, musculoskeletal, genitourinary, immunological, dermatological, endocrine, connective tissue diseases or disorders, or had a clinically relevant surgical history,
- Any personal or family history of haemostatic disorder,
- Any personal or family history of bleeding complications after surgery or tooth extraction, nose or gingival bleeding, or haemorrhagic diathesis,
