Research Overview
Calcitonin
Calcitonin has been evaluated in randomized trials and reviews for pain associated with vertebral compression fractures and other bone-related conditions. The signal is strongest for short-term analgesia rather than long-term chronic pain control.
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.
