Neuropathy, Pain
Conditions
Brief summary
The purpose of this study is to assess the efficacy of Gabapentin (Carbatin & Neurontin) in patients with neuropathy pain.
Interventions
DRUGCarbatin
Carbatin® or Neurontin® is initiated at 100 mg at night and slowly titrated to 300\ 800 mg three times/day over 4 to 25 days. The dose of Carbatin® or Neurontin® taken by each patient will amount to 100 to 2400 mg /day oral if the pain intensity reaches a VAS score ≧4. The maintenance dose of Carbatin® or Neurontin® will throughout for at least 14 days of the treatment period.
DRUGNeurontin
Carbatin® or Neurontin® is initiated at 100 mg at night and slowly titrated to 300\ 800 mg three times/day over 4 to 25 days. The dose of Carbatin® or Neurontin® taken by each patient will amount to 100 to 2400 mg /day oral if the pain intensity reaches a VAS score ≧4. The maintenance dose of Carbatin® or Neurontin® will throughout for at least 14 days of the treatment period.

Inclusion criteria
* Subjects who have been diagnosed the disease of neuropathy pain arising from diabetic peripheral neuropathy, postherpetic neuralgia, traumatic/surgical nerve injury, incomplete spinal cord injury, or trigeminal neuralgia and if they have a mean weekly pain score of at least 4 on the 100-mm visual analog scale (VAS) of the Short-Form McGill Pain Questionnaire (SF-MPQ) completed a screening / baseline period before randomization. Additional disease-specific inclusion criteria are listed in Table 1. * Subjects must be 20 years of age or older.
Exclusion criteria
* Subjects who are pregnant, lactating or of childbearing potential not using effective contraceptives. * Subjects who have a clinically significant or unstable medical or psychiatric condition. * Subjects who are known of hypersensitivity to Gabapentin. * Serum creatinine \> 1.5 times the upper limit of normal * Subjects who have received nerve blocks or acupuncture for pain relief within four weeks before a screening / baseline period. * Subjects who have the presence of chronic pain other than the target pain being studied (unless the chronic pain is in a different body region than the target pain and its intensity is not greater than that of the target pain). * Subjects who have received nondrug therapies or any special procedures for the relief of the target pain within two weeks before a baseline visit. * Subjects who are using the following agents within 30 days prior to screening: antidepressants, opioids, other anticonvulsants, local anaesthetic injections or any investigational drug.
