Randomized Controlled Trial Multicenter Study Clinical TrialTopiramate in painful diabetic polyneuropathy: findings from three double-blind placebo-controlled trials.
To evaluate the efficacy and tolerability of topiramate in patients with painful diabetic polyneuropathy. ⋯ These studies did not find topiramate to be significantly more effective than placebo in reducing pain scores in patients with painful diabetic polyneuropathy. Several design features may have precluded the studies from having sufficient sensitivity to differentiate effective and ineffective treatments. The study design and results are instructive for other investigators designing future clinical studies in neuropathic pain.
