Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Insulin analog that lowers blood glucose by binding to insulin receptors, enhancing peripheral glucose uptake, and inhibiting hepatic glucose production.
Insulin aspart is a rapid-acting recombinant human insulin analog. It lowers blood glucose by binding to insulin receptors on skeletal muscle and adipose tissue, promoting glucose uptake, and inhibiting hepatic glucose production via glycogenolysis and gluconeogenesis.
Subcutaneous injection: 0.5-1 unit/kg/day divided into 3 or more doses given within 15 minutes before or after meals. Typical total daily dose range 0.5-1.5 units/kg.
Subcutaneous injection: 0.5-1 unit/kg/day divided into multiple doses (e.g., basal-bolus regimen). Individualized based on glucose monitoring.

Terminal elimination half-life is 1.2-1.5 hours in healthy individuals, reflecting rapid clearance. In renal impairment (e.g., eGFR <30 mL/min), half-life may be prolonged up to 2-3 hours due to reduced degradation.
~5-7 minutes (free insulin aspart); clinical effect duration correlates with SC absorption half-life ~1-2 hours
Renal excretion accounts for approximately 60-80% of insulin aspart degradation products; unchanged drug is minimally excreted. Biliary/fecal excretion is negligible (<10%).
Renal: 60-80% as metabolites; unchanged drug excreted minimally. Fecal: <10%
