A1C (%) Normal: 4-6% Fasting/Preprandial (mg/dL)(plasma equivalent) Postprandial (mg/dL) (2-hour) ADA <7.0 90-130 <180* ACE <6.5 <110 <140 * Peak Targets for Glycemic Control Goals for individual patients may vary. Aim for the Lowest A1C Possible without Hypoglycemia. American Diabetes Association. Clinical Practice Recommendations.

Relative Contribution of FBG and PPG Varies With A1C Range Inc PPG increases Micro- and macro- vascular disease Thus , to get to glycemic goals, one must control PPG as well as FBS. (incretins, alpha-glucosidase inhibitors, TZDs, glinides, fast-insulin analogues) Adapted from Monnier L, et al. Diabetes Care. 2003;26:881-885.
Non-Insulin Therapy for Hyperglycemia in Type 2 Diabetes,Treating Defronzo’s Octet: Match Patient Characteristics to Drug Characteristics - - - Peripheral glucose uptake 1.Pancreatic insulin Secretion: Incretin, ranolazine 5.Gut CHO Absorption: Incretin, Pramlintide, Glucosidase inh. 7.Brain- TZD,INCRETIN, bromocryptine 2.Pancreatic glucagon Secretion- Incretin 8.Kidney- SGLT2 HYPERGLYCEMIA De 3.Muscle- TZD, Incretin Hepatic glucose production: Metformin, incretin 4.Liver 6.Fat- TZD, metformin
Revised Treatment Algorithm At diagnosis: Lifestyle + metformin STEP 1 Tier 1* Tier 2† HbA1C >7.0% STEP 2 Add basal insulin Add sulfonylurea Add GLP-1 agonist Add pioglitazone ± SU Intensive insulin STEP 3 The New ADA Guidelines for Type 2 Diabetes:AKA- David Nathan’s Regimen- DNR NOT Glyburide, chlorpropamide NOT Rosiglitazone
Simplified- AACE/ACE:Recommendations Based on A1C at Diagnosis Lifestyle Modifications Monotherapy Dual therapy Triple therapy A1C 6.5%-7.5% A1C 7.6%-9.0% A1C >9.0% If under treatment If drug naive Symptoms No symptoms Dual therapy Insulin plus other agent(s)* Insulin plus other agent(s)* Triple therapy Triple therapy *Pramlintide can be used with prandial insulin, but insulin secretagogues should be discontinued with multidose insulin Therapeutic Choice, based on Safety/ Efficacy, Should Match The Drug Characteristics With Patient Characteristics Rodbard HW, et al.

Summary Treat aggressively-benefit on cost and complications Treat elements of pathophysiology Resistance-glycemia,endothelial dysfunction,lipids,BP,coag. Secretion-first phase,incretin,importance of PPG Multi-hormonal issues Use SIDE-BENEFITS of the various agents Treat to new goals using combinations that make pathophysiologic sense Guidelines should help pick right drug(s) for right patients
