Review Article


Since the approval of bolus insulin, it has been used frequently in clinical practice for the management of type 1 and 2 diabetes mellitus for postprandial control. Another new product is faster insulin aspart (Fiasp, Novo Nordisk), a fast-acting insulin with 100 units/mL. Several studies have been conducted evaluating the pharmacokinetics and pharmacodynamics of faster insulin aspart, compared with insulin aspart. This new bolus insulin provides greater glucose-lowering effect at 20 min, following subcutaneous administration. Faster insulin aspart had a greater reduction in hemoglobin A1c concentrations from baseline in patients with type 1 diabetes mellitus when compared with insulin aspart, whereas the two bolus insulins were similar in this outcome in patients with type 2 diabetes mellitus. Depending on the trial, the safety profile may differ between these two insulins with severe or confirmed hypoglycemia. Based on the clinical evidence for efficacy and safety, faster insulin aspart can be considered a viable option for those patients with type 1 and 2 diabetes mellitus who desire to inject immediately prior to a meal or within 20 min following a meal. However, additional studies should be completed to determine the role of faster insulin aspart in pregnant and pediatric patients, along with patients prescribed insulin pumps. This article evaluates and summarizes the pharmacokinetics and pharmacodynamics of faster insulin aspart for patients with type 1 or 2 diabetes mellitus, and summarizes its application to clinical practice.
