Hormonal comparison

Glucagon (GlucaGen / Baqsimi) vs Insulin Lispro (Humalog)

An educational, source-based comparison of Glucagon (GlucaGen / Baqsimi) and Insulin Lispro (Humalog) — how each peptide works, what it's researched for, and what to know before going deeper.

Counter-regulatory Hormone · Endocrine
Glucagon (GlucaGen / Baqsimi)

29-amino-acid peptide hormone for severe hypoglycemia.

Mechanism

Pancreatic alpha-cell peptide hormone that activates hepatic glucagon receptors, stimulating glycogenolysis and gluconeogenesis to raise blood glucose; also relaxes GI smooth muscle (used in radiology).

Research areas
  • Severe hypoglycemia (T1D/T2D)
  • Beta-blocker overdose
  • GI motility (imaging adjunct)
Considerations
  • FDA-approved.
  • Nausea/vomiting common after recovery.

Insulin Analog · Endocrine
Insulin Lispro (Humalog)

Rapid-acting mealtime insulin analog.

Mechanism

Recombinant insulin analog with reversed lysine and proline at B28/B29, reducing self-association so it acts within ~15 minutes for postprandial glucose control.

Research areas
  • Prandial coverage in T1D/T2D
  • Insulin pump therapy
  • Hyperglycemic crises (with caution)
Considerations
  • FDA-approved.
  • Hypoglycemia risk if meal delayed or skipped.

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.
