False - metformin rarely induces hypoglycemia

Q

How does Pioglitazone (Actos) work?

A

decreases hepatic glucose output and increases uptake in skeletal muscle, liver, and adipose tissue

65
Q

How do GLP-1 receptor agonists work?

A

enhance insulin secretion by pancreas

Name 2 GLP-1s

A

exenatide (Byetta)

liraglutide (Victoza)

When should you use liraglutide (Victoza)

A

as adjunct to diet and exercise (not studied in combination with insulin)

69
Q

How does amylin analogue pramlintide (Symlin) work?

A

a naturally occurring hormone made in pancreatic beta cells

  • slows gastric emptying
  • suppresses postprandial glucagon secretion
  • decreases appetite
70
Q

When should you take pramlintide (Symlin)

A

In addition to insulin

-before mealtime

71
Q

How do dipeptidyl peptidase IV (DPP-4) inhibitors work?

A

block the action of DPP-4 which is known to degrade incretin (hormone that stimulates pancreas to release insulin)

72

Januvia- monotherapy, metformin, thiazolidinediones
Onglyza- diet and exercise

74
Q

How do insulins work?

A

act on target tissues (liver, skeletal muscle, adipose) to regulate metabolism of carbs, protein, and fats.
