Use of 50/50 Premixed Insulin Analogs in Type 2 Diabetes: Systematic Review and Clinical Recommendations

Introduction Premixed insulin analogs represent an alternative to basal or basal–bolus insulin regimens for the treatment of type 2 diabetes (T2D). “Low-mix” formulations with a low rapid-acting to long-acting analog ratio (e.g., 25/75) are commonly used, but 50/50 formulations (Mix50) may be more appropriate for some patients. We conducted a systematic literature review to assess the efficacy and safety of Mix50, compared with low-mix, basal, or basal–bolus therapy, for insulin initiation and intensification.
