IDegLira: Redefining insulin optimisation using a single injection in patients with type 2 diabetes

With complementary modes of action, glucagon-like peptide-1 receptor agonists (GLP-1RAs) and a basal insulin in combination offer an alternative to basal-bolus therapy in T2D. This review describes the rationale behind this treatment combination and presents clinical data available for IDegLira, the first basal insulin (insulin degludec) and GLP-1RA (liraglutide) co-formulation available in one pen for a single injection daily.
