Gabapentin for pain control in cancer patients' wound dressing care

A patient with mycosis fungoides illustrates the problem of pain management during wound care and suggests the utility of a novel treatment, gabapentin. Skin lesions, be they induced through necrosis of tumor, therapy (e.g., radiotherapy), or by pressure ulceration, are often the cause of continuous pain or acute wound dressing pain. Optimizing the analgesic treatment in those patients is thus of major importance. Anti-inflammatory drugs and opioids are the cornerstones in the treatment of cancer pain but are rarely sufficient to control wound pain. Different adjuvant techniques can be used, including topical analgesics, psychological distraction techniques, anxiolytics, and co-analgesics. There is growing evidence that anticonvulsants, and sodium channel blockers in particular, are effective not only in neuropathic but also in inflammatory pain. Gabapentin, a voltage sensitive sodium and calcium channel blocker, was used as a co-analgesic to supplement morphine in this case of cancer wound dressing pain.
