| E.1 Medical condition or disease under investigation |
| E.1.1 | Medical condition(s) being investigated |
| Post herpetic hyperalgesia |
|
| MedDRA Classification |
| E.1.3 | Condition being studied is a rare disease | No |
| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| The aim is to study the hypothesis, that PHZ hyperalgesia is reversed by intravenous remifentanil at a plasma target concentration of 18ng/ml for 60 minutes. |
|
| E.2.2 | Secondary objectives of the trial |
| Secondary outcome parameters as area of secondary hyperalgesia assessed by pinprick, area of dynamic allodynia, numeric rating scale (NRS), mechanical pain threshold, heat pain perception threshold (HPPT), heat pain tolerance threshold (HPTT) at baseline and +140min., coolness, warmth, and laser doppler perfusion imaging (LDPI, PeriScan PIM II System, Perimed, Stockholm, Sweden) will be analyzed analogously. |
|
| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
• Patients suffering from PHN. • Pain ≥ 4 out of 10 in numeric rating scale (NRS) • Female and male patients above the age of 18 • Ability to understand/write/read german
|
|
| E.4 | Principal exclusion criteria |
• Any of the following will exclude a subject from the study: • Zoster affecting trigeminal-, opticus region • Any somatic pain which is stronger than the neuropathic pain • Severe progressive disease • Acute cardiac decompensation • Known cardiac valve dysfunction • Known pulmonary hypertension • Cardiac conduction disturbance • Active herpetic lesion • Analgesic or antitussive opioid therapy • Bronchial asthmal • Known chronic obstructive pulmonary disease (COPD) >GOLD II • Severe psychiatric condition • Abuse of alcoholic beverages, drug abuse • Negative neuropathic symptoms • Pregnancy or breast feeding • Participation in a clinical trial in the 2 weeks preceding the study • Allergy against any medication used in the study protocol

|
| E.5 End points |
| E.5.1 | Primary end point(s) |
| Our primary outcome parameter being S/R function, we will analyze the within-subject difference at baseline -20min versus 140min (80min after the end of remifentanil). |
