Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Insulin lispro is a rapid-acting insulin analog that lowers blood glucose by binding to insulin receptors on skeletal muscle and adipocytes, leading to increased glucose uptake and reduced hepatic glucose production.
Novolin 70/30 is a biphasic insulin analog consisting of 70% insulin aspart protamine suspension (intermediate-acting) and 30% insulin aspart (rapid-acting). It lowers blood glucose by promoting peripheral glucose uptake, inhibiting hepatic gluconeogenesis, and suppressing lipolysis and proteolysis.
Subcutaneous injection: 0.2-1.0 units/kg/day divided into 3 or more doses, given within 15 minutes before or immediately after a meal. Typical total daily dose range 0.5-1.0 units/kg/day.
Subcutaneous injection, 0.5-1 unit/kg/day divided into 2-3 doses, typically before meals and at bedtime; adjust based on blood glucose monitoring.

Subcutaneous: 0.5-1.0 hour (insulin lispro); longer with renal impairment (up to 1.5-3 hours).
Terminal half-life for NPH component is approximately 13 hours; regular insulin component half-life is 5-6 hours. Clinical context: Provides basal coverage for 18-24 hours.
Renal: 60-80% as unchanged drug; biliary/fecal: minor (<10%).
Renal: 30-80% of administered insulin is excreted via kidneys; remainder is metabolized in liver and muscle. Biliary/fecal excretion is negligible.
