ABSTRACT
The progressive nature of type 2 diabetes mellitus (T2DM) renders the shifting of patients from oral drugs to insulin therapy an inevitability in most patients especially in those with long duration of diabetes. At the turn of the last millennium, neutral protamine Hagedorn (NPH) insulin was still the only long-acting insulin available for people with diabetes. The advent of the first truly long-acting basal insulin, i.e. insulin glargine 100 U/mL (Gla-100) brought to the table a remarkably long duration of action and a very minimal risk of hypoglycemia by due to less pronounced peaks in their action profile. Further, in trying to achieve fasting normoglycemia, Gla-100 has demonstrated remarkably more holistic glucose-lowering efficacy in several pivotal trials compared to other insulin formulations, such as premixed insulin and coformulations-apart from NPH insulin. This article delineates clinical data on the effectiveness of Gla-100 vs. other insulin formulations in the context of T2DM.
