Cochrane Review: Group Based Diabetes Education in People with T2DM Hemoglobin A1C Difference -1.4% -0.8% -1.0% Type 2 DM: What About Medications? Deakin T, et al. Cochrane. 2009. Medications to Treat Type 2 Diabetes Mellitus Metformin vs. Metformin ER: Reduced GI Side Effects Metformin 1946 1995 2005 2013 Metformin ER 1921 1957 Adapted from Nathan D. N Engl J Med 2007;356:437-440 Type 2 Diabetes Medications Oral s T2DM: Sulfonylureas and Meglitinides Metformin Failure: What s Next? Sulfonylureas (glyburide, glipizide, glimepiride) Meglitinides (repaglinide, nateglidnide) -1 to 2% Binds sulfonylurea receptor on -cells, stimulates insulin -1 to 1.5% Binds sulfonylurea receptor on -cells, stimulates insulin Extensive experience, improved microvascular outcomes Short acting, targets postprandial glucose Hypoglycemia, weight gain Hypoglycemia, weight gain
Sulfonylureas and Meglitinides: DPP IV inhibitors An inexpensive, oral medication with a well-known risk profile. Relatively strong in its A1C lowering effect and has a higher risk of hypoglycemia Elderly or others at risk of hypoglycemia Erratic eating habits Beta cell mass preservation (not fully proven) Sitagliptin (Januvia) Saxagliptin (Onglyza) Linagliptin (Tradjenta) -0.5 0.9% Inhibit degradation of GLP-1 and GIP Minimal hypo risk No weight gain 1. Pancreatitis / Pancreatic CA (?) 2. Nasopharyngitis and UTI 3. Renal Adjustment except Linagliptin Alogliptin (Nesina) Kahn SE, et al. NEJM 2006 DPP IV Inhibitors = Pills DPP IV Inhibitors: GLP-1 Receptor Agonists An oral medication with a modest A1C lowering effect and no associated weight gain. There is no risk of hypoglycemia (elderly) and probably negligible other side effects. Those concerned about cost or theoretical risk of pancreatitis & pancreatic cancer Exenatide (Byetta) Liraglutide (Victoza) Exenatide LAR (Bydureon) -0.5 1.5% GLP-1 receptor agonist Minimal hypo risk Weight Loss 1. Nausea, diarrhea, vomiting 2. Acute pancreatitis / Pancreatic CA (?) 3. Acute renal failure 4. Thyroid C-Cell tumors 5. Contraindications: (a) Gastroparesis (b) Cr Clearance < 30 Albiglutide (Tanzeum) Dulaglutide (Trulicity) GLP-1 RA = Injectables 25 GLP-1 Receptor Agonists: Thiazolidinediones (TZDs) Those aiming for weight loss in addition to a relatively strong A1C lowering effect. Additionally, little to no hypoglycemia. Those concerned about cost (brand name), using an injectable medication or the possibility of pancreatitis & pancreatic cancer Pioglitazone (Actos) Rosiglitazone (Avandia) -1 to 2% Activates PPAR-, increase peripheral insulin sensitivity No Hypoglycemia Improves insulin sensitivity Possibly beta cell sparing 1. Edema 2. Weight gain 3. Fractures 4. Monitor LFTs 5. Symptomatic heart failure 6. Liver dysfunction 7. Bladder Cancer
Thiazolidinediones (TZD): Sodium Glucose Co-transporter 2 (SGLT2) Inhibitors In those wishing for a relatively strong A1C lowering effect from an oral medication without hypoglycemia. It is also low-cost. Who might not want to use this medication? In patients concerned about weight gain or at higher risk for heart failure, fracture risk. Dapagliflozin (Farxiga) Canagliflozin (Invokana) Empagliflozin (Jardiance) Mechanism of -0.5 to 1% Enhance renal glucose excretion No hypoglycemia Blood pressure reduction Weight neutral / weight loss Genitourinary Infections *Dapagliflozin use not recommend GFR < 60 *Canagliflozin use not recommend GFR < 45 (100 mg if GFR <60) SGLT2 Inhibitors: In patients looking for a pill that is relatively efficacious in A1C lowering without weight gain or hypoglycemia risk. Additionally, those looking for a positive CVD effect. Patients concerned about new medications without a long-term track record. Additionally, patients worried about the diuretic effect or GU infections. What Basal Insulin to add? NPH Glargine Detemir Glargine U300 Degludec
