Ibutamoren is a non-peptidic, potent, long-acting, orally-active, and selective agonist of the ghrelin receptor and a growth hormone secretagogue. It mimicks the growth hormone (GH)-stimulating action of the endogenous hormone ghrelin. It stimulates GH release from rat pituitary cells in vitro (EC50 = 1.3 nM) and enhances GH plasma levels in vivo.
