Analgesic effect of corticotropin-releasing hormone: involvement of the hypothalamic-pituitary-adrenocortical axis into its realization

Bull Exp Biol Med. 2006 Feb;141(2):184-6. doi: 10.1007/s10517-006-0123-2.

Abstract

Involvement of hypothalamic-pituitary-adrenocortical axis into the analgesic effect of corticotropin-releasing hormone after its systemic administration was studied in experiments on rats. Pharmacological blockade of the hypothalamic-pituitary-adrenocortical axis decreased the duration and degree of the analgesic effect of corticotropin-releasing hormone. This analgesic effect can be mediated via two pathways: related to hormones of the hypothalamic-pituitary-adrenocortical axis and independent of these hormones.
