Macimorelin (Macrilen) vs Pegvisomant (Somavert)
An educational, source-based comparison of Macimorelin (Macrilen) and Pegvisomant (Somavert) — how each peptide works, what it's researched for, and what to know before going deeper.
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.
Pegylated GH receptor antagonist for acromegaly.
Genetically engineered analog of human GH with site-directed mutations blocking functional dimerization of the GH receptor; pegylation extends half-life. Lowers IGF-1 without lowering GH.
- Acromegaly inadequately controlled by surgery, radiation, or somatostatin analogs
- • FDA-approved.
- • Monitor LFTs; tumor monitoring via MRI required.
- • Lipohypertrophy at injection sites.
