Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticotropin (ACTH) stimulates the adrenal cortex to release glucocorticoids, mineralocorticoids, and androgens. In gel formulation, zinc complex prolongs absorption, providing sustained adrenocortical stimulation.
Corticotropin (ACTH) stimulates the adrenal cortex to release cortisol, corticosterone, and aldosterone; used diagnostically to assess adrenal function.
40-80 units subcutaneously or intramuscularly every 24-72 hours, titrated to individual patient 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.

Terminal half-life: 16-24 hours; clinical context: prolonged due to zinc complex, allows once-daily dosing
Terminal half-life approximately 1.5 hours (dose-dependent: 1.1-2.2 h). Rapid clearance limits duration of action.
Renal: ~90% as metabolites; biliary/fecal: ~10%
Primarily renal (90% as metabolites, 10% unchanged); negligible biliary/fecal.
