title: Initiation and Intensification Strategies in Type 2 Diabetes Management: A Comparison of Basal Plus and Premix Regimens.
abstract: The progressive nature of type 2 diabetes (T2D) often results in the need for initiation and subsequent intensification of insulin treatment to achieve glycemic control. The aim of this review is to examine published clinical evidence that has directly compared two recommended treatment approaches in patients with T2D: (1) a 'basal plus' regimen, whereby 1-2 injections of prandial insulin are added to basal insulin; or (2) the use of once- or twice-daily premix insulin analogs, which contain both basal and prandial insulin in a single injection. Broadly, the available evidence suggests that both basal plus and premix regimens are comparable in terms of efficacy and safety when used for insulin initiation in insulin-naïve patients and intensification in patients who have failed on basal insulin; instances of greater glycemic control are observed with premix insulin; however, these are often accompanied by increases in hypoglycemia and/or weight relative to basal plus treatment, and results should be interpreted within the context of total insulin doses used. Relatively low numbers of patients achieved glycemic control when both regimens were used for insulin intensification following failure of basal insulin, suggesting that a full basal-bolus regimen and/or the use of different treatments is clinically indicated in certain patients. In summary, the current review argues that both basal plus and premix insulin regimens are relatively efficacious and safe options for patients with T2D during both insulin initiation in insulin-naïve patients and intensification in patients who have failed on basal insulin. This emphasizes the important role of patient-centered factors in clinical decision-making.
