HUMALOG vs Insulin
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.
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.
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.
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: 0.5-1.0 hour (insulin lispro); longer with renal impairment (up to 1.5-3 hours).
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.
Renal: 60-80% as unchanged drug; biliary/fecal: minor (<10%).
Renal: ~60-80% (degraded in kidney); hepatic: ~20-40% (degraded in liver); only a small fraction (<1%) excreted unchanged in urine.
