CORTICOTROPIN vs CORTROSYN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Corticotropin (ACTH) stimulates the adrenal cortex to release cortisol, corticosterone, and aldosterone; used diagnostically to assess adrenal function.
40-80 units IM or SC every 24-72 hours; dose adjusted based on response.
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.

15-30 minutes (intravenous); clinically, duration of action (via adrenal stimulation) exceeds half-life due to sustained cAMP-mediated effects.
Terminal half-life approximately 1.5 hours (dose-dependent: 1.1-2.2 h). Rapid clearance limits duration of action.
Primarily metabolized in tissues via proteolysis; negligible renal excretion of intact hormone (<5%); urinary metabolites include small peptide fragments.
Primarily renal (90% as metabolites, 10% unchanged); negligible biliary/fecal.
