Insulin degludec (IDeg) is a basal insulin with an ultralong duration of action. Upon injection into the subcutaneous tissue, it forms a depot of soluble multihexamers from which insulin monomers are slowly and continuously absorbed into the circulation (19). This mechanism of protraction results in a half-life of 25.4 hours, a flatter pharmacokinetic and pharmacodynamic profile, and a significantly decreased within-patient day-to-day variability compared with IGlar (20,21). Thus, IDeg has attributes which would be expected to have a lower risk for hypoglycemia than IGlar.
