Effects of Gabapentin in the Treatment of Neuropathic Pain on Driving Performance and Cognition

Effects of Pain and the Treatment of Pain With Gabapentin (900-3600 Mg) on Driving Ability, Attentional Capacity and Psychomotor Performance in Chronic Neuropathic Pain Patients

• Status: Terminated
• Phase: Phase 4
• Study type: Interventional
• Enrollment: 24 (planned)

• Healthy volunteers: Not accepted

Summary

The aim of this study was to explore the effects of pain on the one hand and the effects of treatment of pain with gabapentin (900, 1200, 1800 or 2400 mg) on the other hand on actual driving performance and several laboratory tests in patients with neuropathic pain. It was hypothesized that gabapentin might influence performance after acute but not after subchronic administration.

Detailed description

Numerous studies demonstrate neuropsychological impairment in patients with chronic pain, particularely on measures assessing attentional capacity, processing speed and psychomotor speed. About 50% of the patients suffering from neuropathic pain are treated with anticonvulsants, as a treatment against serious pain complaints, and experience good pain relief. Gabapentin is one of the most prescribed anticonvulsants for the treatment of neuropathic pain. An important disadvantage of treatment with gabapentin could be the occurrence of side effects, such as somnolence and fatigue. These side effects can constitute a crucial problem for patients treated with gabapentin who must operate a motor vehicle or other dangerous machinery. However, pain affects cognition negatively, and possibly also driving. Therefore, another possibility is that treatment with gabapentin for these pain complaints can improve driving because the pain has less influence. Since driving is an activity of daily living that is important in maintaining independency in the community, such as access to employment and social activities, it is important to establish the effects of using gabapentin on these abilities. No studies have been conducted so far to investigate driving abilities of patients with neuropathic pain, treated with gabapentin.The aim of this study was to explore the effects of pain on the one hand and the effects of acute (Day 1) and subchronic (Day 15) treatment of pain with gabapentin (900, 1200, 1800 or 2400 mg) on the other hand on actual driving performance and several laboratory tests in patients with neuropathic pain. It was hypothesized that gabapentin might influence performance after acute but not after subchronic administration. This study is a two-period double-blind, placebo-controlled, cross-over randomised study.
