Q

What do incretins do?

A

Incretins are gut hormones which increase insulin secretion.

22
Q

Name two incretins.

A

GLP-1 (Glucagon like peptide 1)GIP (Glucose-dependant insulinotropic peptide)

23
Q

What three primary effects does GLP-1 have on the body?

A
  • Lowers glucose levels.- Increases insulin secretion.***- Lowers glucagon.
24
Q

Incretin therapies may?

A

Inhibit GLP-1 breakdown or act as GLP-1 mimetics that are resistant to breakdown.

25
Q

What are some of the effects of incretin therapies?

A
  • Reduce blood glucose levels.- Low risk of hypoglycemia.- Weight loss- Increase/preservation of beta cell function.- Nausea and vomiting.
26
Q

What are the effects of an SGLT2 inhibitor?

A
  • Lower blood glucose.- No hypoglycemia.- Weight loss.- Lower blood pressure.- Risk of UTI / Genital infections.
27
Q

What T2DM antihyperglycemic agent causes flatulence?

A

The Alpha Glucosidase Inhibitor Acarbose.

28
Q

What T2DM antihyperglycemic agent precipitates to form microcrystals after injection?

A

Glargine (Lantus) - a long lasting insulin analog.

29
Q

What drug has an acylated at B29 to increase self association?

A

Detemir (Levamir) - a long lasting insulin analog.

30
Q

Which insulins act faster? Rapid analogs or short-acting analogs?

A
