Randomized Controlled Trial Multicenter Study Clinical Trial
Oxcarbazepine in painful diabetic neuropathy: a randomized, placebo-controlled study.
In this multicentre, placebo-controlled, 16-week trial, the efficacy and safety of oxcarbazepine monotherapy in patients with neuropathic pain of diabetic origin was evaluated. Eligible patients had a 6-month to 5-year history of neuropathic pain symptoms of diabetic origin and a pain rating of > or =50 units on the visual analogue scale (VAS). Oxcarbazepine was initiated at a dose of 300 mg/day and titrated to a maximum dose of 1800 mg/day. ⋯ Patients on oxcarbazepine were awakened less frequently due to pain than patients on placebo. Most adverse events were mild to moderate in severity, transient, and in line with the known tolerability profile of oxcarbazepine. These observations suggest that oxcarbazepine monotherapy, pending additional trials, may be efficacious and may provide clinically meaningful pain relief in patients with neuropathic pain of diabetic origin.
