Research Overview
Nociceptin
Nociceptin is a major pain-pathway peptide in the spinal cord, brainstem, and trigeminal system. Its relevance to migraine and neuropathic pain is mainly preclinical, where receptor-selective tools are being explored.
Cosyntropin
Cosyntropin is not a standard pain drug, but it appears in headache literature because ACTH analogs can help some patients with difficult migraine attacks. The analgesic rationale is partly tied to steroidogenic and anti-inflammatory effects.
