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.
DADLE
DADLE has been studied for analgesic, neuroprotective, and receptor-selective opioid effects in animal and tissue models. It remains important as a mechanistic probe because it is more stable than endogenous enkephalins but still peptide-like in its delivery constraints.
