- Subject is in good general health with (in the opinion of the investigator) no clinically significant and relevant abnormalities as assessed by medical history, physical examination, electrocardiogram (ECG) and clinical laboratory test results (hematology, biochemistry and urinalysis) are within normal limits.
- If female, subject of childbearing potential is practicing a reliable method of contraception in the opinion of the investigator.
- Subject understands and is willing, able, and likely to comply with all study procedures and restrictions.

- A medical history which, in the opinion of the investigator, might impact the validity of the study results and may require pharmacotherapy or prevent the subject from finishing the study.
- Oral surgery within 4 weeks of dosing, dental work or extractions within 2 weeks of dosing, or presence of any clinically significant (as determined by the principal investigator) oral pathology including lesions, sores or inflammation.

- Subject has participated in another clinical study or received an investigational drug within 30 days of the first study session or previously participated in this study.
- Subject has donated or experienced significant blood loss within 56 days of Visit 2, donated plasma within 7 days of Visit 2, or has a hemoglobin value of <12.0g/dL.
- Subject has been treated with any known enzyme-altering agents (e.g., barbiturates, phenothiazines, cimetidine, theophyllines) within 30 days prior to the first study session.
- Subject has used any nicotine replacement therapy within 21 days prior to the first study session.
- Subject has used any over-the-counter (OTC) medication or herbal supplements within 48 hours prior to administration of study treatment.
