| Sglt2 sodium-glucose cotransporter-2 | Empagliflozin(Jardiance), canagliflozin (Invokana), dapagliflozin ( Farxiga) |
| MOA SGLT2 | Proximal tubule excrete glucose |
| Effects of SGLT2 | A1c .5-.7, Wt loss 2-3 kg, lower BP, Positive CVD outcome and with Nephropathy, No hypoglycemia |
| SGLT2 Contraindication | GFR< 30, Bladder cancer risk, Prior DKA |
| Side Effects of SGLT2 | Lactic acidosis, GU infection, foot infection, bone fx, increase LDL, bladder cancer. Monitor Cr q 3 mo. |
| Insulin - When to start? | A1c > 9, FBG> 250, RBG> 300, Ketone in urine |
| Insulin replacement | 0.6-1.0 U/kg as 50% basal (Glargine) and 50% prandial( Aspart/Lispro). Gen: Start 10 U Glargine at night and titrate up 2 U Q 3 days until FBG b/w 90-140. Can add Apart to largest meal at 2-3 U and titrate to PPG goal of < 180 |
| Insulin types | Long acting : Glargine : (Lantus, Basaglar, Toujeo up to 36 hours, Degludec, Tresiba up to 42 hours. Insulin vials 1000 Units last 1 mo, Pens ( 300 U: Box of 5 pens ( 1500 U /box) |
| Sulfunylureas | 2nd generation: glyburide and glipizide - renal , 3rd generation: glimepiride- once a day with no renal clearance and 5x potent Short acting glipizide and glimepiride reduce hypoglycemia |
| SU MOA and SE | Increase insulin sensitivity SE: wt gain, hypoglycemia |
