Abstract
Insulin degludec/insulin aspart (IDegAsp) is the first soluble co-formulation which combines two insulin analogues, and provides effective basal and prandial glycemic coverage. It has been assessed as basal insulin in type 2 diabetes mellitus (T2DM), and as part of basal-bolus regime in both type 1 diabetes mellitus and T2DM. Insulin degludec has also been assessed as flexibly administered basal insulin in terms of time of administration. This review discusses data pertaining to the efficacy, safety, tolerability, and clinical potential of IDegAsp. The discussion includes comparisons of IDegAsp with basal as well as premixed insulin.
