Diabetes Mellitus T2 (Chapter 56) Oral Hypoglycemic Agents for Type 2 Diabetes

What is the mechanism of action for Alpha-glucosidase inhibitors?

Acts on Small Intestines
Works by reducing the amount of glucose that the intestines absorb from food. This prevents the sharp rise in blood sugar levels that people with diabetes typically experience after meals. One medication in this class, acarbose, may also help increase the body's insulin sensitivity, further helping to reduce blood sugar levels.

What is the mechanism of action for Sulfonylureas?
The "Ides"

Acts on Beta Cells of Pancreas & Tissues
↑insulin release from pancreas,
↑tissue response to insulin
[as the duration of diabetes ↑, beta cell function ↓ and these drugs become ↓effective]

What is the mechanism of action for Meglitinides?
The "Ides"

Acts on Beta Cells of Pancreas
↑insulin release from pancreas,
acts more rapidly and ↓duration of action than Sulfonylureas

What is the mechanism of action for Thiazolidinediones (TZDs)?

Acts on Liver & Target Cells
Decreases hepatic blood glucose production
Improves target cell response to insulin
↑insulin sensitivity of adipose tissue, skeletal muscle,
liver (↓ insulin resistance at receptor sites on cells)

What are the side effects of Sulfonylureas?

Hypoglycemia (especially with elderly with renal or liver failure), cardiac ischemia, weight gain

What is the mechanism of action for Biguanides?

Acts on Liver, Small Intestines, & Target Cells
Biguanides work by:
decreasing the liver's production of glucose
decreasing the small intestines' absorption of glucose
improving your body's ability to use insulin, improves glucose transport into cells.
