• Current evidence or history of significant medical illness or organic brain impairment, including syndrome of inappropriate antidiuretic hormone secretion (SIADH), diabetes insipidus (DI), stroke, epilepsy, CNS tumor, demyelinating disease, cardiac, pulmonary, gastrointestinal, renal or hepatic impairment that would likely interfere with the action, absorption, distribution, metabolism, or excretion of SRX246, or influence psychophysiological responses.
• Current evidence of median nerve entrapment or carpal tunnel syndrome.
• Any laboratory abnormality that in the investigators' judgment is considered to be clinically significant (ECG, TSH, LFT, etc.).
• Abnormal urine specific gravity (below 1.00 or above 1.03) as documented by urine sample refractometry.
• Subject who has resting blood pressure outside of a systolic blood pressure range of 90-140 mmHg or a diastolic blood pressure outside a range of 50-90 mmHg on two consecutive measurements taken up to 10 minutes apart.
• Subject who has resting pulse rate greater than 100 bpm or less than 50 bpm on two consecutive measurements taken up to 10 minutes apart.

• Lack of measurable startle response (3 times the baseline EMG activity) for all 9 startles used during the habituation visit.
• Subjects who would be noncompliant with the visit schedule or study procedures. Possible noncompliance may include planned vacations or planned hospitalizations during the study.
• For women who are able to get pregnant and men who are able to father a child, unwillingness to use at least two effective birth control methods for 15 days prior to the time they enroll in the study, and for 15 days after their last exposure to the study drug.
