Cosyntropin (Cortrosyn) vs Macimorelin (Macrilen)
An educational, source-based comparison of Cosyntropin (Cortrosyn) and Macimorelin (Macrilen) — how each peptide works, what it's researched for, and what to know before going deeper.
Synthetic peptide containing the first 24 amino acids of ACTH — retains full corticotropic activity. Stimulates adrenal cortisol release for diagnostic testing.
- Primary and secondary adrenal insufficiency diagnosis
- • FDA-approved.
- • Single diagnostic dose; very well tolerated.
Oral ghrelin agonist for diagnosing adult growth hormone deficiency.
Oral ghrelin receptor (GHSR-1a) agonist that stimulates pituitary GH release; peak GH response is measured to evaluate adult GH deficiency.
- Diagnostic test for adult GH deficiency
- • FDA-approved.
- • Avoid with QT-prolonging drugs.
- • Hold strong CYP3A4 inducers prior to test.
