Insulin Lispro (Humalog) Mechanism of Action
Recombinant insulin analog with reversed lysine and proline at B28/B29, reducing self-association so it acts within ~15 minutes for postprandial glucose control.

Insulin Lispro (Humalog) — Frequently Asked Questions
Insulin aspart vs lispro — are they equivalent?+
Insulin aspart (Novolog) and insulin lispro (Humalog) are both rapid-acting mealtime insulin analogues with very similar pharmacokinetics — onset ~10–15 minutes, peak ~1–2 hours, duration ~3–5 hours. Randomized crossover studies show broadly comparable HbA1c reduction, postprandial glucose control, and hypoglycemia rates when used equivalently in basal-bolus regimens. Choice is often driven by insurance coverage and delivery-device preference (pen vs pump compatibility).
Humalog vs Novolog — is there a clinical difference?+
In head-to-head comparisons the two rapid-acting analogues perform similarly on postprandial glucose excursion and rates of severe hypoglycemia. Small differences in absorption kinetics exist but rarely change clinical outcomes. Most guidelines treat them as clinically interchangeable within rapid-acting analogue insulin therapy.
