Pharmacokinetics of commonly used insulin preparations

Pharmacokinetics of commonly used insulin preparations
(A) Prandial insulin
Insulin type Approximate onset of action Effective peak Approximate duration of action*
Lispro, lispro-aabc, aspart, faster aspart, glulisine 15 to 30 minutes 1 to 3 hours 4 to 6 hours
Regular 30 minutes 1.5 to 3.5 hours 8 hours
(B) Basal insulin
Insulin type Half-lifeΔ Effective peak Approximate duration of action*
NPH 4.4 hours 4 to 6 hours 12 hours
Insulin glargine
U-100 12 hours No pronounced peak 20 to >24 hours
U-300 19 hours No pronounced peak 20 to >24 hours
Insulin detemir 5 to 7 hours 3 to 9 hours 6 to 24 hours
Insulin degludec (U-100, U-200) 25 hours No pronounced peak >24 hours
* Glucose-lowering action may vary considerably in different individuals or within the same individual; the duration of action is dose dependent.
¶ Lispro-aabc and faster aspart have quicker pharmacokinetic profiles than standard lispro and aspart.
Δ In general, it takes 4 half-lives to reach steady state. Dose adjustments should not be made until after steady state is achieved.
◊ At higher doses (≥0.8 units/kg), mean duration of action is longer and less variable (22 to 23 hours).
