Q

Sulfonylureas- how it works and names

A

stimulate the pancreas to release more insulin

2nd generations: glipizide(glucotrol), glyburide, glimepride

Q

Biguanides- how it works and names

A

decreases hepatic glucose production and intestinal glucose absorption
Metphormin (glucophage)
Good adjunct to the sulfonylureas but can be used alone especially in obese patients

Q

How do alpha-glucosidase inhibitors work and give some names

A

bind to disaccharides more readily than sucrose, so less glucose is absorbed by the gut
acarbose (precose)
miglitol (glyset)

Q

How does Pramlintide (Symlin) work?

A

Injectable for type 1&2DM, resembles human amylin, slows the absorption of glucose and inhibits the actions of glucagons: promotes weight loss while decreased glucose levels
