Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Insulin replacement therapy. Human insulin is a recombinant DNA-derived polypeptide hormone that regulates glucose metabolism. Insulin binds to the insulin receptor, activating tyrosine kinase activity, which leads to increased glucose uptake in peripheral tissues (e.g., skeletal muscle, adipose tissue), inhibition of hepatic gluconeogenesis, and promotion of glycogen synthesis and lipogenesis.
Insulin lispro and insulin lispro protamine suspension. Insulin lispro lowers blood glucose by binding to insulin receptors on skeletal muscle and adipose tissue, facilitating glucose uptake, and inhibiting hepatic glucose production. Insulin lispro protamine provides intermediate-acting basal coverage.
Subcutaneous injection, 0.5-1.0 units/kg/day divided into two doses (before breakfast and before dinner), adjusted based on blood glucose monitoring.
Subcutaneous injection, individualized based on metabolic needs and blood glucose monitoring; typical starting dose for type 1 diabetes: 0.5 to 0.6 units/kg/day in divided doses (usually twice daily with 70% intermediate-acting NPH and 30% regular insulin); for type 2 diabetes: 0.2 units/kg/day initially, adjusted per glycemic response.

0.5-1 hour (free insulin); 8-12 hours (prolonged due to NPH component, reflecting duration of action).
The terminal elimination half-life of insulin in Humulin 70/30 is approximately 1.5 hours for the regular insulin component and 4-6 hours for the NPH component due to protamine suspension, resulting in a prolonged duration of action.
Renal: 100% (metabolized to inactive fragments; negligible excretion of intact insulin).
Insulin is primarily eliminated via renal metabolism and excretion; approximately 30-80% is cleared by the kidneys, with the remainder undergoing hepatic metabolism. Biliary/fecal excretion is negligible (<1%).
