Research Overview
Neurotensin
Neurotensin has reproducible analgesic and neuromodulatory effects in preclinical studies, especially in inflammatory and neuropathic pain paradigms. It is not a standard clinical analgesic, but it is a real non-opioid peptide with pain-relevant biology.
Ziconotide
Clinical studies and post-marketing data support ziconotide as an analgesic for severe chronic pain that does not respond to conventional therapy. Research focuses on balancing analgesic efficacy with neuropsychiatric tolerability and careful dose titration.
