Q

Agents used in the management of diabetes:

A

a. False, Metformin decreases blood glucose levels by decreasing hepatic glucose production (gluconeogenesis), decreasing the intestinal absorption of glucose, and increasing insulin sensitivity by increasing peripheral glucose uptake and utilization

20
Q

Oral hypoglycaemic agents
e.
glibenclamide causes an increase in plasma glucose levels

A

e. False, Sulfonylureas and Meglitinides are insulin secretagogues and therefore will decrease plasma glucose levels
