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.
Regular insulin lowers blood glucose by promoting peripheral glucose uptake, especially in skeletal muscle and adipose tissue, and by inhibiting hepatic glucose production. It binds to insulin receptors on cell membranes, activating tyrosine kinase activity and downstream signaling pathways that regulate glucose transport and metabolism.
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: 0.5-1 unit/kg/day divided into 2-3 doses; intravenous: continuous infusion starting at 0.05-0.1 units/kg/hr adjusted based on blood glucose.

Subcutaneous: 0.5-1.0 hour (insulin lispro); longer with renal impairment (up to 1.5-3 hours).
Intravenous: 5-10 minutes (short due to rapid distribution and degradation). Subcutaneous: 1-2 hours (terminal half-life after absorption).
Renal: 60-80% as unchanged drug; biliary/fecal: minor (<10%).
Renal (tubular reabsorption and metabolism). Approximately 50-80% of insulin is degraded in the liver and kidneys; the remainder is excreted in urine as metabolites and intact hormone (<1%).
