Primary outcome measures

In each period, a total of 18 blood samples will be drawn from each subject for pharmacokinetic analyses. Blood samples will be collected prior to drug administration and 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 8, 12, 24, 36, 48, and 72 hours post-dose (3 mL for each sampling time).

Blood pressure and heart rate will also be measured prior to dosing and approximately 2, 4, 8, and 24 hours post-dose. Oral temperature will be measured at screening and at study exit.

A urine drug screen (amphetamines, methamphetamines, barbiturates, benzodiazepines, tetrahydrocannabinol, cocaine, opiates, phencyclidine, MDMA, methadone) and a urine cotinine test will be performed at screening. A urine drug screen, a urine cotinine test, and an alcohol breath test will be performed before dosing of each period

Secondary outcome measures

1. Blood pregnancy
2. Test demographic datamedical and medication histories
3. Physical examination
4. Body measurements
5. Electrocardiogram (12-lead ECG)
6. Vital signs (blood pressure, heart rate, and respiratory rate)
7. Oral temperature
8. Hematology - HIV, hepatitis B and C tests
9. Biochemistry
10. Urinalysis
