A 55-year-old patient with numbness in the feet and a history of type 2 diabetes; which medication is licensed for diabetic peripheral neuropathy pain?

• A. Ibuprofen
• B. Gabapentin
• C. Duloxetine
• D. Amitriptyline

Answer: (C)

Diabetic peripheral neuropathy pain is a neuropathic pain condition that benefits from medications with established licensed indications for that specific problem. Duloxetine is licensed for diabetic peripheral neuropathy pain, and clinical trials show it reliably reduces neuropathic pain and can improve sleep and function. It works as a serotonin-norepinephrine reuptake inhibitor, enhancing descending pain inhibition in the spinal cord, which helps explain its effectiveness in this type of pain. Because of its approved status for this indication, it stands out as the best answer when the question asks for a medication with a licensed use for DPN pain. Ibuprofen mainly targets inflammatory pain, not neuropathic pain, so it isn’t the appropriate licensed option for DPN. Gabapentin is effective for many neuropathic pains and is used widely, but licensing for diabetic peripheral neuropathy varies by country, so it isn’t universally the licensed choice for this indication. Amitriptyline, a tricyclic antidepressant, can help neuropathic pain but carries anticholinergic and cardiovascular risks and is not specifically licensed for diabetic peripheral neuropathy in many settings.
