Objectives Review current criteria for the diagnosis of diabetes mellitus, especially with the updated use of HbA1C Describe current and upcoming therapies for Type 2 Diabetes Construct an algorithm for diabetes therapy.
Current criteria for diagnosis Fasting plasma glucose 126 mg/dl Two-hour plasma glucose 200 mg/dl post OGTT Random plasma glucose 200 mg/dl with symptoms HbA1C 6.5 % NGSP standard, nonfasting, hemoglobinopathies In the absence of unequivocal hyperglycemia, repeat test ADA 2011 Diabetes Care, 34 : S1

Objectives Review current criteria for the diagnosis of diabetes mellitus, especially with the updated use of HbA1C Describe current and upcoming therapies for Type 2 Diabetes CLASSICS, NEW, ODD Construct an algorithm for diabetes therapy.
Pharmacotherapy for diabetes: CLASSICS Decrease Glucose absorption α-glucosidase inhibitors Acarbose miglitol Decrease Insulin demand Biguanides Metformin TZD Rosiglitazone Pioglitazone Increase Insulin supply Sulfonylureas Glimepiride Gliclazide Glyburide Glipizide Meglitinides Repaglinide Nateglinide Insulin Plasma glucose
Pharmacotherapy for diabetes: NEW GLP-1 agonists Secreted by intestine in response to glucose Slows gastric emptying, increase insulin, decrease glucagon Levels are low in diabetes DPP-IV inhibitors Prevents breakdown of endogenous GLP-1 Amylin analogs Co-secreted with insulin
Pharmacotherapy for diabetes: NEW Decrease Glucose absorption α-glucosidase inhibitors Decrease Insulin demand Biguanides TZD Increase Insulin supply Sulfonylureas Meglitinides Insulin GLP-1 agonists Exenatide, liraglutide DPP-IV inhibitors Sitagliptin, saxagliptin,vildagliptin Amylin analogs Pramlintide Plasma glucose
Pharmacotherapy for diabetes: ODD Decrease Glucose reabsorption Decrease Glucose absorption Decrease Insulin demand Increase Insulin supply SGLT2 inh Dapagliflozin α-glucosidase inhibitors Colesevelam Biguanides TZD Sulfonylureas Meglitinides Insulin GLP-1 agonists DPP-IV inhibitors Bromocriptine Amylin analogs Plasma glucose
Degree of HbA1C lowering MILD, MODERATE, HIGH Decrease Glucose reabsorption Decrease Glucose absorption Decrease Insulin demand Increase Insulin supply SGLT2 inh α-glucosidase inhibitors Colesevelam Biguanides TZD Sulfonylureas Meglitinides Insulin GLP-1 agonists DPP-IV inhibitors Bromocriptine Amylin analogs Plasma glucose
Effect on weight INCREASE, MILD/NEUTRAL, DECREASE Decrease Glucose reabsorption Decrease Glucose absorption Decrease Insulin demand Increase Insulin supply SGLT2 inh α-glucosidase inhibitors Colesevelam Biguanides TZD Sulfonylureas Meglitinides Insulin GLP-1 agonists DPP-IV inhibitors Bromocriptine Amylin analogs Plasma glucose
Customizing therapy Risk factor control Certain side-effects Additional points Metformin and vitamin B 12 deficiency Pioglitazone and bladder ca Pioglitazone and osteoporosis Dapagliflozin and breast and bladder ca DPP IV inhibitors and pancreatitis GLP-1 agonists and pancreatitis GLP-1 and medullary ca thyroid http://secure.medicalletter.org 2011 Drugs for T2D
