Ipamorelin reading list

The bowel studies sit within a much wider ghrelin-receptor literature. These are the sources behind the discussion.

Bowel movement and gastric emptying

Venkova and colleagues’ postoperative-ileus rat study follows fecal output, intake and weight. Greenwood-Van Meerveld and colleagues’ gastric-dysmotility experiment concentrates on stomach emptying and mechanism. The published bowel-resection trial is the human test of the clinical idea.

Hormones, appetite and safety

The founding selectivity paper and human pharmacokinetic model describe the hormone response. The mouse adiposity experiment makes a usefully awkward companion to those hormone papers, along with the rat safety study of a different ghrelin agonist. They broaden the questions raised by a selective GH pulse. The full reading list follows.
