45 Summary Diabetes independently increases many serious consequences Glucose lowering clearly reduces eye & kidney disease with controversial effects on other consequences Glucose lowering drugs have important non-glycemic effects: Glargine, degludec, nateglinide, sitagliptin, alogliptin, saxagliptin, lixisenatide & acarbose safe, neutral effect on CVD Empagliflozin, canagliflozin, liraglutide, semaglutide & albiglutide reduce CVD & renal disease; exenatide may reduce death Pioglitazone reduces CVD in non-dm at risk for stroke Several nonglycemic therapies that work in people without diabetes also have protective effects in diabetes

46 Many Proven Ways to Reduce Outcomes in T2 DM We knew exactly how to reduce outcomes when we had no good data but now, after ~ 15 years of good clinical outcomes trials, we know how to reduce serious health outcomes in people with diabetes
