Tabimorelin (INN) (developmental code name NN-703) is a drug which acts as a potent, orally-active agonist of the ghrelin/growth hormone secretagogue receptor (GHSR) and growth hormone secretagogue, mimicking the effects of the endogenous peptide agonist ghrelin as a stimulator of growth hormone (GH) release.

It was one of the first GH secretagogues developed and is largely a modified polypeptide, but it is nevertheless orally-active in vivo.

[1] Tabimorelin produced sustained increases in levels of GH and insulin-like growth factor 1 (IGF-1), along with smaller transient increases in levels of other hormones such as adrenocorticotropic hormone (ACTH), cortisol, and prolactin.

[2][3] However actual clinical effects in adults with growth hormone deficiency were limited, with only the most severely GH-deficient patients showing significant benefit,[4] and tabimorelin was also found to act as a CYP3A4 inhibitor which could cause it to have undesirable interactions with other drugs.
