In neuropathic pain, what common characteristic makes management challenging compared to acute pain responsive to traditional medications?

Answer

Insensitivity to opioid analgesics like morphine

Neuropathic pain often displays resistance to opioid treatment. This resistance is sometimes attributed to reduced expression of mu-opioid receptors or increased counter-modulatory action from neuropeptides like cholecystokinin (CCK).
