Exclusion Criteria

· Malignancy within the past 2 years with the exception of basal cell carcinoma.
· Patients with significant hepatic impairment (i.e. AST/ALT>2x ULN, Total bilirubin >2 x ULN)
· Clinically significant abnormal 12-lead ECG (in the opinion of the investigator).
· Neurological disorders unrelated to PHN that may confuse the assessment of neuropathic pain.
· Any pain or other condition that may confound assessment or self-evaluation of the pain due to PHN.
· History of chronic hepatitis B or C, acute hepatitis A, B or C within the past 3 months, or HIV infection.
· Skin conditions in the area affected by the neuropathy that (in the opinion of the investigator) could alter sensation.

· Postural hypotension (a fall of 20mmHg in systolic BP or 10mmHg in diastolic BP on standing).
· History of transient ischemic attack or stroke.
· Carotid bruit, unless significant carotid stenosis (e.g. >70%) has been excluded by appropriate investigation.
· History of uncontrolled narrow angle glaucoma.
· History of epilepsy or seizure disorder.
