ACTH vs CORTICOTROPIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ACTH (corticotropin) stimulates the adrenal cortex to release cortisol, corticosterone, aldosterone, and androgenic steroids. It binds to the melanocortin 2 receptor (MC2R) in the adrenal gland, activating adenylyl cyclase and increasing intracellular cAMP.
Corticotropin (ACTH) stimulates the adrenal cortex to release cortisol, corticosterone, aldosterone, and androgens via activation of melanocortin 2 receptor (MC2R) in the zona fasciculata and reticularis.
40-80 units intramuscularly or subcutaneously every 24-72 hours for chronic conditions; 25 units intravenously over 8 hours for diagnostic use.
40-80 units IM or SC every 24-72 hours; dose adjusted based on response.

15 minutes (intravenous); rapid clearance due to enzymatic degradation; clinical effect persists 2-4 hours due to steroidogenesis
15-30 minutes (intravenous); clinically, duration of action (via adrenal stimulation) exceeds half-life due to sustained cAMP-mediated effects.
Renal: <5% unchanged; hepatic metabolism via proteolysis; <1% biliary/fecal
Primarily metabolized in tissues via proteolysis; negligible renal excretion of intact hormone (<5%); urinary metabolites include small peptide fragments.
