Further study details as provided by Odense University Hospital:

Primary Outcome Measures:
  • Pain relief [ Time Frame: After 1 month treatment ]

Secondary Outcome Measures:
  • Pain intensity measured daily on numeric rating scales [ Time Frame: During treatment periods ]

Enrollment: 25
Study Start Date: March 2004
Study Completion Date: September 2006
Intervention Details:
    Drug: Levetiracetam (drug)
    The starting dose of levetiracetam was 500 mg/day and the dose was increased with 500 mg every other day to 6 tablets of 500 mg (Keppra, UCB, Belgium), divided into two doses daily corresponding to 3000 mg/day. The dose was kept at this level throughout the remaining treatment period - 4 weeks total. Six placebo tablets with identical appearance were dosed similarly to levetiracetam in the placebo phase.
    Other Name: Keppra, Levetiracetam
Detailed Description:
This study is a randomised, placebocontrolled, doubleblind study on the effect of the antiepileptic drug, levetiracetam, in patients suffering from PMPS. The treatment periods are 1 month each and the periods are separated by a 1-week washout period. The daily dose of levetiracetam is increased over a 2-week period to 3.000 mg/day. The primary effect variable is pain relief by the use of numeric rating scale. Secondary parameters are daily registration of pain performed by the patients during the treatment periods and the amount of escape medicine used (paracetamol and tramadol). Sensory testing is performed at baseline and after each treatment period.
