Growth hormone-releasing peptide 2 (GHRP-2), is a growth hormone secretagogue used as a diagnostic agent that is marketed by Kaken Pharmaceutical in Japan in a single-dose formulation for the assessment of growth hormone deficiency.
Pralmorelin is an orally-active, synthetic peptide drug, specifically, an analog of met-enkephalin, with the amino acid sequence D-Ala-D-(β-naphthyl)-Ala-Trp-D-Phe-Lys-NH2. It acts as a ghrelin/growth hormone secretagogue receptor agonist and was the first of this class of drugs to be introduced clinically. Acute administration of the drug markedly increases the levels of plasma growth hormone and reliably induces sensations of hunger and increases food intake in humans.
