Which medications are commonly used for managing neuropathic pain in diabetes?

• A. Amitriptyline and duloxetine
• B. Gabapentin and pregabalin
• C. Ibuprofen and acetaminophen
• D. Metformin and glyburide

Answer: (B)

Neuropathic pain in diabetes responds best to medicines that directly dampen nerve signaling in the pain pathways. Gabapentin and pregabalin, belonging to the gabapentinoid class, do this by binding to the alpha-2-delta subunit of voltage-gated calcium channels in the spinal cord. This reduces the release of excitatory neurotransmitters that drive abnormal pain signals, leading to meaningful pain relief for many people with diabetic neuropathy. These drugs are commonly started as first-line therapy because of their proven effectiveness, tolerability, and straightforward dosing, with manageable side effects such as dizziness, somnolence, and possible edema that can be adjusted for kidney function. While antidepressants like amitriptyline or duloxetine can also treat neuropathic pain, gabapentinoids are among the most frequently used options in practice for diabetic neuropathy. Non-neuropathic analgesics like ibuprofen or acetaminophen don’t address the underlying abnormal nerve signaling and offer limited relief for neuropathic pain. Metformin and glyburide, on the other hand, manage blood glucose rather than pain signaling.
