There are many classes of oral diabetes medications, all of which help in lowering blood glucose levels. These different classes of diabetes medications can be used in combination or with insulin to achieve control of the blood sugar.
Classes and actions of medications:
- Sulfonylureas stimulate the pancreas to make more insulin. The second- and third-generation ones are the best.
- Biguanides shut off the liver’s excess glucose production
- Alpha-glucosidase Inhibitors slow absorption of carbs in the intestine
- Thiazolidinediones increase the body’s sensitivity to insulin
- Meglitinides stimulate the pancreas to make more insulin
- DPP-4 Inhibitors help increase insulin release after meals and when glucose levels are high
- GLP-1 Agonist lowers both glucagon and glucose levels
- SGL2 Inhibitors causes glucose to be excreted in the urine
