Insulin vs NOVOLIN 70/30
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Insulin lowers blood glucose by binding to insulin receptors on target cells, activating tyrosine kinase activity, promoting glucose uptake via GLUT4 translocation, stimulating glycogen synthesis, and inhibiting gluconeogenesis and lipolysis.
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.
Individualized based on weight, insulin sensitivity, and metabolic needs. Type 1 diabetes: total daily dose (TDD) 0.3–1.5 units/kg/day, typically 50% basal (long-acting) and 50% prandial (rapid/short-acting). Type 2 diabetes: starting dose 0.1–0.2 units/kg/day or 10 units basal once daily, titrated based on fasting glucose. Intensive regimens use basal-bolus approach.
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.

Terminal elimination half-life: 5-6 minutes for regular insulin; biphasic with initial rapid phase (4-5 min) and slower phase. Clinical context: short half-life necessitates continuous infusion or multiple daily injections.
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% (degraded in kidney); hepatic: ~20-40% (degraded in liver); only a small fraction (<1%) excreted unchanged in urine.
Renal: 30-80% of administered insulin is excreted via kidneys; remainder is metabolized in liver and muscle. Biliary/fecal excretion is negligible.
