Neuropathic pain in cancer patients is often difficult to treat, requiring a combination of several different pharmacological therapies. We describe two patients with complex neuropathic pain syndromes in the form of phantom limb pain and Brown-Sequard syndrome who did not respond to conventional treatments but responded dramatically to the addition of levorphanol. Levorphanol is a synthetic strong opioid that is a potent N-methyl-d-aspartate receptor antagonist, mu, kappa, and delta opioid receptor agonist, and reuptake inhibitor of serotonin and norepinephrine. It bypasses hepatic first-pass metabolism and thereby not subjected to numerous drug interactions. Levorphanol's unique profile makes it a potentially attractive opioid in cancer pain management.
