Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Biphasic insulin analog combining rapid-acting insulin aspart and intermediate-acting protamine-crystallized insulin aspart, which lowers blood glucose by stimulating peripheral glucose uptake and inhibiting hepatic glucose production.
Novolog Mix 70/30 is a biphasic insulin analog suspension containing 70% insulin aspart protamine (intermediate-acting) and 30% insulin aspart (rapid-acting). Insulin aspart binds to the insulin receptor (IR) on target cells (muscle, adipose, liver), activating tyrosine kinase signaling, which promotes glucose uptake via GLUT4 translocation, inhibits hepatic gluconeogenesis, and stimulates glycogen synthesis and lipogenesis.
Subcutaneous injection only. Typical total daily insulin dose ranges from 0.5 to 1.0 units/kg/day divided into two or three injections. Administer twice daily, with each dose given within 15 minutes before meals. Dose individualization based on glycemic targets and previous insulin regimen is required.
Subcutaneous injection, typically 0.5–1 unit/kg/day divided into two doses: two-thirds in the morning and one-third in the evening, adjusted based on blood glucose levels.

Insulin aspart (free component): ~1-2 hours; protamine-crystallized component: ~8-10 hours. Clinical context: Duration of action up to 24 hours due to the intermediate-acting component.
Biphasic: first phase (distribution) 0.5-1 h; terminal (elimination) 5-7 h (insulin aspart component). Clinical context: covers prandial and basal needs with twice-daily dosing.
Renal: 30-80% of dose excreted unchanged in urine for insulin aspart; for protamine-crystallized component, metabolism and renal elimination also occur. Biliary/fecal: Minor.
Renal: 100% (protamine and insulin are metabolized and excreted via kidneys; no unchanged drug excreted in urine). Biliary/fecal: negligible.
