Ulimorelin (INN, USAN) (developmental code name TZP-101) is a drug with a modified cyclic peptide structure which acts as a selective agonist of the ghrelin/growth hormone secretagogue receptor (GHSR). Unlike many related drugs, ulimorelin is peripherally selective and has little or no effect on growth hormone (GH) release,[1] instead having a specific laxative effect.[2][3] It has been researched for enhancing gastrointestinal motility, especially in gastroparesis[4] and in aiding recovery of bowel function following gastrointestinal surgery, where opioid analgesic drugs used for post-operative pain relief may worsen existing constipation.[5][6][7][8] Human trial results have been promising, however a common side effect of reduced blood pressure led to the discovery that ulimorelin also acts as an antagonist of α1-adrenoceptors in addition to its intended mechanism of ghrelin receptor agonism.[9]
