(ACE) 2009 glycemic control algorithm. Pathways are provided for patients with hemoglobin Ale (A1C) in 3 ranges: 6.5% to 7.5%, >7.6% to 9.0%, and >9.0%. There is a progression from rnonotherapy, to dual therapy, to triple therapy, to insulin therapy with or without additional agents. The order of presentation of regimens indicates general priorities that should be customized to the individual patient, with consideration of contraindications and precautions, allergies, comorbid conditions, drug-drug interactions, and drug-laboratory interactions. Physicians must be thoroughly familiar with complete prescribing information before selection of therapy. In each case, response to therapy should be monitored closely (determination of A1C every 2 to 3 months), and titration of dosages or changes of regimen should be implemented in a timely manner. Rx = treatment. Note accompanying Table of Annotated Abbreviations for Figure 1.

Table Al. Outline of Various Types of Insulin
Type of insulin
Rapid-acting insulin analogues
with reduced risk of hypoglycemia 2-5 hours after a meal or overnight Premixed insulin/protamine
breakfast and dinner; provides postprandial coverage with 2 injections per day; less flexible than use of basal-bolus therapy with a combination of rapid-acting and long-acting analogues Long-acting insulin analogues
patients with type 2 diabetes; excellent reproducibility of absorption profile within individuals; possibly less weight gain than with other insulins Not recommended
persistence of effect is too long to mimic a normal prandial physiologic profile; the result is impaired efficacy and increased risk of delayed hypoglycemia "peakless" basal insulin; highly variable absorption even within individuals; increased risk of hypoglycemia compared with the long-acting insulin analogues glargine or detemir TableA2 Summary of Insulin Regimens
