Microneedle-Based Intradermal Versus Subcutaneous Administration of Regular Human Insulin or Insulin Lispro: Pharmacokinetics and Postprandial Glycemic Excursions in Patients with Type 1 Diabetes

Abstract

PPG with RHI administered ID via microneedle was improved versus SC delivery when dosed 17 min premeal. ID RHI provided similar control of PPG as SC IL immediately premeal. Further studies of ID insulin delivery via steel microneedles are warranted.
