BACKGROUND: Neuropathic pain is often severe and adversely affects patients’ quality of life.

OBJECTIVE: To perform a retrospective, observational study investigating the efficacy and safety of treating refractory chronic neuropathic pain with 5% lidocaine-medicated plaster, in patients attending pain centres.

METHODS: Medical records from 467 patients treated with 5% lidocaine-medicated plaster were evaluated for efficacy (maximum and minimum pain intensities and coanalgesic consumption) and adverse events. Data from an initial assessment and at least one follow-up visit had to be available, and separate analyses were conducted for the general population and the subpopulation older than 70 years of age.

RESULTS: Of the patients enrolled, 25.0% were older than 70 years of age. While 20.6% had postherpetic neuralgia, 76.3% had other types of peripheral pain. Approximately 78.1% of cases of peripheral neuropathic pain followed surgery, and 23% were post-traumatic pain. The time from onset to referral was more than one year in two-thirds of cases. All patients experienced pain of at least moderate severity (mean [± SD] 11-point numerical rating scale score 5.2±2.4 to 8.2±1.6). Treatment with 5% lidocaine-medicated plaster reduced pain intensity by more than 50% in 45.5% of patients, and by at least 30% in 82.2%. Of note, the consumption of analgesics and coanalgesics was significantly reduced. Results were similar in both the general population and the subpopulation older than 70 years of age, at high risk and often receiving multiple medications.

CONCLUSIONS: Treatment of refractory neuropathic pain with 5% lidocaine-medicated plaster clearly demonstrated efficacy and an excellent safety profile in patients with refractory neuropathic pain.
