Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Visual Analogue Scale (VAS) of pain is higher than 40 mm.
* Pain is sustained for more than 3 months after healing of herpes zoster skin rash.

Exclusion Criteria

* Malignancy within the past 2 years.
* Patients who have undergone neurolytic or neurosurgical therapy for postherpetic neuralgia.
* Creatinine clearance \</= 30 mL/min (estimated from serum creatinine, body weight, age, and sex using the Cockcroft and Gault equation, by omitting any decimal fractions).
