Women of childbearing potential (WOCBP) and men must be using an acceptable method of contraception to avoid pregnancy throughout the study, and for women 30 days and men 90 days after the last dose of investigational product in such a manner that the risk of pregnancy and risk to pregnancy is minimized. 8.

Subjects who have experienced a seizure while taking isoniazid (INH), phenothiazines, chlorpromazine, thioridazine, theophylline, or tricyclic antidepressants such as amitriptyline. 11. Use of any analgesic up to 2 days prior to screening or has a need to use these drugs during the screening period and throughout the time period of the trial. This includes NSAIDs such as ibuprofen, diclofenac, indomethacin, sulindac, tolmetin, ketoprofen, flurbiprofen, naprozen, opioids such as codeine, hydrocodone, hydromorphone, morphine, oxycodone and aspirin, or acetaminophen. 12.

Use of MAO Inhibitor drugs up to14 days prior to screening or has a need to use these drugs during the screening period and throughout the time period of the trial. 14. Subjects who have experienced a seizure while taking isoniazid (INH), phenothiazines, chlorpromazine, thioridazine, theophylline, or tricyclic antidepressants such as amitriptyline.

Uncontrolled hypertension is defined as systolic blood pressure greater than or equal to 140 mm Hg or diastolic blood pressure greater than or equal to 90 mm Hg. 16. Has a known personal or family history of hereditary pseudocholinesterase deficiency. Study participants will be screened by asking about personal or family history of anesthetic reaction, anesthetic death, and previous diagnosis of psuedochloinesterase deficiency in a relative or personally. Subjects identified with pseudocholinesterase deficiency are at risk for delayed recovery with certain anesthetics (e.g. succinylcholine and ester-based anesthetics). 17. Has a known personal or family history of pheochromocytoma. Study participants will be specifically asked if they have been treated for a pheochromocytoma previously or if they have a family member who has been diagnosed with pheochromocytoma (since 10% of these are familial). 18. Has a known personal or family history of adrenal tumor. 19.

Has screening 12-lead ECG findings of any abnormalities. Generally, these are current or prior myocardial ischemia or infarction, dysrhythmia, or risk of serious dysrhythmia (such as prolonged QT interval). An exception to this would be if sinus bradycardia or sinus tachycardia is present, the Investigator must determine whether this finding is clinically relevant and exclusionary 21.
