• •Subject has a history of seizures and/or significant head trauma.
• •Subject has an abnormal cardiac condition including any of the following:
• •* Medically significant disorders of cardiac rate and/or rhythm
• •* QTc interval \> 450 msec (calculated using Fridericia's correction) or uncorrected QT interval \> 500 msec, PR interval \> 240 msec or ≤ 110 msec, evidence of second or third degree atrioventricular block, pathological Q-waves (defined as Q-wave \> 40 msec or depth \> 0.5 mV), evidence of ventricular pre-excitation, complete left bundle branch block, and/or resting heart rate outside the range of 40 to 120 beats per minute
• •Subject has evidence of clinically significant abnormal laboratory values including the following:
• •* Impaired kidney function (i.e., serum creatinine ≥ 1.5 mg/dL)
• •* Impaired liver function (laboratory test values ≥ 3 times the upper limit of normal \[ULN\] for aspartate aminotransferase or alanine aminotransferase, or values \> 2 times the ULN for alkaline phosphatase), or total bilirubin level \> 1.5 times the ULN or, in the opinion of the investigator, liver function impairment to the extent that the subject should not participate in this study
• •* Presence of Gilbert's Syndrome or any known hepatobiliary abnormalities
• •* Any other laboratory values judged as clinically significant by the investigator
• •Subject has a history of chronic or sustained intake of opioid drugs in the preceding 12 months, or has taken any medication containing opioid compounds in the month preceding entry to this trial.
• •Subject has a history of alcohol or substance abuse or addiction within 2 years before screening and/or routine consumption of 3 or more alcohol-containing beverages per day. Subject has consumed alcohol within 3 days before administration of study drug or cannot abstain for the duration of confinement to the clinical unit.
• •Subject has a prior history of intolerance to opioid drugs, their excipients, or related compounds.
• •Subject has positive urine test for alcohol, cotinine, or drugs of abuse at screening or check-in. If a subject is excluded for a positive drug screen due to prescribed medication for pain from an infected molar, the subject may be rescreened after the appropriate washout period.
• •Subject has used any medication (with the exception of vitamins and contraceptives), including over-the-counter medications, herbal and/or mineral supplements, dietary supplements, or has ingested grapefruit-containing foods or beverages within 3 days before administration of study drug, or cannot abstain for the duration of confinement to the clinical unit.
• •Subject has ingested caffeine-containing foods or beverages (e.g., coffee, tea, chocolate, and colas) within 24 hours before administration of study drug or cannot abstain for the duration of confinement to the clinical unit.
• •Subject has smoked or used other nicotine products within 3 days before study drug administration or cannot abstain for the duration of confinement to the clinical unit.
• •Subject has the presence of any conditions possibly affecting drug absorption (e.g., gastrectomy or malabsorption) or has taken oral medications that affect gastric acid availability (including H2 antagonists, proton-pump inhibitors, and antacids) within 3 days before administration of study drug.
• •Subject has any current dental or medical condition that could prevent safe participation in this study.
• •Subject has significant medical or psychiatric symptoms, cognitive impairment, or other factors which, in the opinion of the investigator, would preclude compliance with the protocol, adequate cooperation in the study, or obtaining informed consent.
