Abstract

An 8-mm needle length is commonly used for insulin injections; however, recent recommendations suggest shorter needles may help patients avoid intramuscular injections and reduce pain, while maintaining adequate glucose control. The goal of these analyses was to compare the pharmacokinetics (PK) and glucodynamics (GD) of insulin lispro after a 5-mm or an 8-mm injection depth administration in 2 populations: normal weight (study 1) or obese (study 2).
