Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Insulin lispro lowers blood glucose by binding to insulin receptors, increasing glucose uptake in skeletal muscle and adipose tissue, and inhibiting hepatic glucose production.
Insulin is a hormone produced by the pancreas that regulates glucose metabolism. Exogenous insulin replaces endogenous insulin, binding to insulin receptors on cell surfaces, activating tyrosine kinase activity, and promoting glucose uptake, glycogen synthesis, and lipogenesis while inhibiting gluconeogenesis and lipolysis.
Subcutaneous injection, individualize based on metabolic needs and blood glucose monitoring. Typical starting total daily insulin dose in type 1 diabetes: 0.5-1 unit/kg/day, with 50-60% as basal and 40-50% as prandial. In type 2 diabetes, initial total daily dose: 0.2-0.4 units/kg/day, with adjustments. Administer 30 minutes before meals.
Subcutaneous injection, usual starting dose 0.2 to 0.4 units/kg/day divided into two or more injections; total daily insulin requirements may range from 0.5 to 1.0 units/kg/day.

5-10 minutes (intravenous); subcutaneous: 1.5-2 hours (depot absorption-limited).
Intravenous: plasma half-life is ~5-10 minutes (distribution) and elimination half-life ~1.5-2 hours (reflecting clearance from peripheral compartments). Subcutaneous: prolonged due to absorption rate-limited kinetics; terminal half-life ~5-10 hours.
Renal: 60-80% (metabolized to inactive peptides); hepatic metabolism via insulin-degrading enzyme; remainder reabsorbed in proximal tubule.
Primarily renal (hepatic metabolism to inactive metabolites accounts for <20%); ~30-80% of dose excreted unchanged in urine via glomerular filtration.
