ACTH vs CORTROSYN
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, and aldosterone; used diagnostically to assess adrenal function.
40-80 units intramuscularly or subcutaneously every 24-72 hours for chronic conditions; 25 units intravenously over 8 hours for diagnostic use.
For diagnostic testing of adrenal function: 250 mcg intramuscularly or intravenously as a single dose. For infants and children: 125 mcg intramuscularly or intravenously as a single dose.

15 minutes (intravenous); rapid clearance due to enzymatic degradation; clinical effect persists 2-4 hours due to steroidogenesis
Terminal half-life approximately 1.5 hours (dose-dependent: 1.1-2.2 h). Rapid clearance limits duration of action.
Renal: <5% unchanged; hepatic metabolism via proteolysis; <1% biliary/fecal
Primarily renal (90% as metabolites, 10% unchanged); negligible biliary/fecal.
