To describe the characteristics of patients treated with the capsaicin 8% patch, prescribing conditions, long-term effects of repeat treatment on pain intensity and perception, quality of life, and impact on concomitant medication. ⋯ The data of this post-marketing study meets the request by the French authorities for additional data on conditions of use in everyday practice. They confirmed the tolerance and long-term effect of capsaicin 8% patch in patients with peripheral neuropathic pain in real-world conditions.

[Effect of autophagy on N-methy-D-aspartate receptor and hyperalgesia in a rat model of neuropathic pain].
To investigate the effects of autophagy on N-methy-D-aspartate (NMDA) receptor and its subunit NR2B and behavioral test in a rat model of neuropathic pain (NP). ⋯ NP could regulate the variety of NMDA/NR2B and hyperalgesia via increasing autophagy.

Pregabalin has been approved for the treatment of the neuropathic pain following spinal cord injury (SCI). We performed a systemic review and meta-analysis of randomized, controlled, multicenter trials to evaluate the efficacy and safety of pregabalin for SCI-induced neuropathic pain. ⋯ Our results showed pregabalin was efficacious and might be safe treatment for chronic pain followed SCI.

Injury to peripheral nerves often leads to abnormal pain states (hyperalgesia, allodynia and spontaneous pain), which can remain long after the injury heals. Although opioid agonists remain the gold standard for the treatment of moderate to severe pain, they show reduced efficacy against neuropathic pain. In addition to analgesia, opioid use is also associated with hyperalgesia and analgesia tolerance, whose underlying mechanisms share some commonalities with nerve injury-induced hypersensitivity. ⋯ Finally, some combined therapies that can increase opioid analgesic effectiveness in neuropathic pain treatment are highlighted. SIGNIFICANCE: This review provides evidence of the low benefit of opioid monotherapy in neuropathic pain and analyses the reasons of this reduced effectiveness. Opioid agonists along with drugs targeted to block the sensitization processes induced by MOR stimulation might result in a better management of neuropathic pain.
