4. History of cardiac disorders (other than hypertension) including but not limited to valvular disease, congestive heart failure, angina pectoris, myocardial infarction, or arrhythmia.

5. Any significant cardiovascular disease, hepatic, renal, respiratory, gastrointestinal, endocrine, immunologic, dermatologic, hematologic, neurologic, or psychiatric disease.

6. Any surgical or medical condition that may interfere with the absorption, distribution, metabolism, or excretion of the test article (eg, resection of liver, kidney, gallbladder, or gastrointestinal tract).

7. Acute disease state (eg, nausea, vomiting, infection, fever, or diarrhea) within 7 days before study day 1).

8. History of drug abuse within 1 year before study day 1.

9. Admitted alcohol abuse or history of alcohol use that may interfere with the subject's ability to comply with the protocol requirements.

Physical and Laboratory Findings

10. Clinically significant electrocardiogram (ECG) abnormalities.

11. Any clinically important deviation from normal limits in physical examination findings, vital sign measurements, 12-lead ECGs, or clinical laboratory test results.

12. Positive serologic findings for human immunodeficiency virus (HIV) antigen and antibodies, hepatitis B surface antigen (HBsAg), and hepatitis C virus (HCV) antibodies.

13. Positive findings of urine drug screen (eg, amphetamines, barbiturates, benzodiazepines, cannabinoids, cocaine, opiates, and phencyclidine [PCP]).

14. Troponin T or CK-MB levels above reference range at screening. Allergies and Adverse Drug Reactions

15. History of any clinically important drug allergy (eg, relapsing dermatitis, drug hypersensitivity, drug allergy, hypersensitivity to ingredient in the test articles, angioedema).

Prohibited Treatments

16. Use of any investigational drug within 90 days before study day 1 or prescription drug within 30 days before study day 1.

17. Tobacco use or the consumption of any caffeine-containing products (eg, coffee, tea, chocolate, or carbonated beverages) or alcoholic beverages within 72 hours before study day 1 until the end of the inpatient confinement period.

18. Consumption of grapefruit or grapefruit-containing products within 72 hours before study day 1 until the end of the inpatient confinement period.
