Histamine activates pain-transmitting nerve fibres, releases pain-related neuropeptides, and is painful when injected into the skin. Histamine agonists mimic these effects, suggesting that histamine plays a role in mediating the signal transduction of tissue damage or other painful stimulus. Certain 'antihistamines' (histamine H-1 receptor antagonists) and other antihistaminics are 'analgesic' in preclinical or clinical models. Potential sites of action of these agents include the brain and spinal cord and a specific histamine receptor subtype might be involved (three subtypes have been identified). However, it is possible that other mechanisms account for the analgesic effect.
