After teaching a group of nursing students about antidiabetic drugs, the instructor determines that the teaching was successful when the students identify
which of the following as producing the glucose-lowering effects by delaying the digestion and absorption of carbohydrates in the intestine? Select all that apply.
A) Glimepiride (Amaryl)
B) Metformin (Glucophage)
C) Pioglitazone (Actos)
D) Miglitol (Glyset)
E) Acarbose (Precose)
Ans: D, E
Feedback:
The alpha-glucosidase inhibitors, acarbose (Precose) and miglitol (Glyset), produce their glucose-lowering effects by delaying the digestion and absorption of carbohydrates in the intestine. Glimepiride is a sulfonylurea. Metformin sensitizes the liver to circulating insulin levels and reduces hepatic glucose production. Pioglitazone decreases insulin resistance and increases insulin sensitivity by modifying several processes, resulting in decreased hepatic glucogenesis (formation of glucose from glycogen) and increased insulin-dependent muscle glucose uptake.
