- Healthy male and/or female subjects between the ages of 18 and 55 years, inclusive.
Healthy is defined as no clinically relevant abnormalities identified by a detailed
medical history, full physical examination, including blood pressure and pulse rate
measurement, 12-lead ECG or clinical laboratory tests.
- Body Mass Index (BMI) of 17.5 to 30.5 kg/m^2; and a total body weight >50 kg (110
lbs).
- Evidence or history of clinically significant hematological, renal, endocrine,
pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, or
allergic disease (including drug allergies, but excluding untreated, asymptomatic,
seasonal allergies at the time of dosing).
- Any condition possibly affecting drug absorption (eg, gastrectomy).
- A positive urine drug screen.
- History of regular alcohol consumption exceeding 14 drinks/week for females or 21
drinks/week for males (1 drink = 5 ounces (150 mL) of wine or 12 ounces (360 mL) of
beer or 1.5 ounces (45 mL) of hard liquor) within 6 months of screening.
- Treatment with an investigational drug within 30 days (or as determined by the local
requirement, whichever is longer) or 5 half-lives preceding the first dose of study
medication.
- 12-lead ECG demonstrating QTc >450 msec or a QRS interval >120 msec at screening. If
QTc exceeds 450 msec, or QRS exceeds 120 msec, the ECG should be repeated two more
times and the average of the three QTc or QRS values should be used to determine the
subject's eligibility.
- Pregnant or nursing females; females of childbearing potential, including those with
tubal ligation.
- Use of prescription or nonprescription drugs and dietary supplements within 7 days or
5 half-lives (whichever is longer) prior to the first dose of study medication. Herbal
supplements and hormonal replacement therapy must be discontinued 28 days prior to the
first dose of study medication. As an exception, acetaminophen/paracetamol may be used
at doses of ?1 g/day. Limited use of non-prescription medications that are not
believed to affect subject safety or the overall results of the study may be permitted
on a case-by-case basis following approval by the sponsor.

within 56 days prior to dosing.
- History of sensitivity to heparin or heparin-induced thrombocytopenia.
- Unwilling or unable to comply with the Lifestyle Guidelines described in this
protocol.
- Subjects who are investigational site staff members or subjects who are Pfizer
employees directly involved in the conduct of the trial.
- Other severe acute or chronic medical or psychiatric condition or laboratory
abnormality that may increase the risk associated with study participation or
investigational product administration or may interfere with the interpretation of
study results and, in the judgment of the investigator, would make the subject
inappropriate for entry into this study.
- A positive serology for Hepatitis B or Hepatitis C.
- Subjects who currently smoke.
