Abstract:Pain is an unpleasant subjective sensory and emotional experience associated with tissue damage or the underlying tissue damage. The number of patients worldwide suffering from pain is increasing year by year, but clinically effective means to treat pain are still lacking. Therefore, it is urgent to further find safe and effective novel analgesic strategies. It is known that oxytocin is a hypothalamic neuropeptide with various physiological and social functions, and its role in pain regulation has gained spiked attention besides the classical effects such as deliver and lactation. A key pattern of its potent analgesic effects is mediated by a neural network system composed of oxytocin and oxytocin receptors that are widely linked in the central and peripheral nervous systems, but the specific analgesic mechanisms remain unclear. This paper will briefly introduce oxytocin and oxytocin receptor, and review its preclinical and clinical research progress in pain in recent years, comb through the mechanisms involved of oxytocin and oxytocin receptor system in analgesia, and reveal its value for pain treatment.
