Desmopressin (DDAVP) vs Macimorelin (Macrilen)
An educational, source-based comparison of Desmopressin (DDAVP) and Macimorelin (Macrilen) — how each peptide works, what it's researched for, and what to know before going deeper.
Synthetic vasopressin analog for diabetes insipidus and nocturnal enuresis.
Synthetic analog of arginine vasopressin with enhanced antidiuretic activity and negligible vasopressor effect. Acts on renal V2 receptors to increase water reabsorption; also increases factor VIII and vWF release.
- Central diabetes insipidus
- Primary nocturnal enuresis
- Hemophilia A
- von Willebrand disease type 1
- • FDA-approved.
- • Risk of hyponatremia — limit fluids around dosing.
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.
