Neuropathic pain in patients with cancer often do not respond to both opioid and non-opioid analgesics. Tapentadol has two medical effects: action on the μ opioid receptor and inhibition of noradrenaline reuptake; thus, it is expected to be effective for neuropathic pain. We investigated its effect on neuropathic pain in 40 patients with cancer who received tapentadol between June 2017 and May 2020 at the Japanese Red Cross Nagoya Daini Hospital. We compared the level of neuropathic pain using an NRS before and after tapentadol administration. The NRS score(median)decreased from 7 to 4.5 within 15 days after first administration or dose increase(p<0.05). Twenty-two patients(55%)showed more than 33% improvement in the NRS score. These results suggest that tapentadol may contribute to a reduction in neuropathic pain.
