ACTH vs CORTROPHIN-ZINC
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 glucocorticoids, mineralocorticoids, and androgens. In gel formulation, zinc complex prolongs absorption, providing sustained adrenocortical stimulation.
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 subcutaneously or intramuscularly every 24-72 hours, titrated to individual patient response.

15 minutes (intravenous); rapid clearance due to enzymatic degradation; clinical effect persists 2-4 hours due to steroidogenesis
Terminal half-life: 16-24 hours; clinical context: prolonged due to zinc complex, allows once-daily dosing
Renal: <5% unchanged; hepatic metabolism via proteolysis; <1% biliary/fecal
Renal: ~90% as metabolites; biliary/fecal: ~10%
