Q

Primary action of Secretagogue Medications?

A

Increase insulin secretion from beta cells

THESE CAUSE PROGRESSION OF DM by burning out the beta cells

22
Q

What are 3 primary negative effects of secretagogue medications?

A

THESE CAUSE PROGRESSION OF DM by burning out the beta cells

Weight Gain

Severe Hypoglycemia

23
Q

What are the 2 classes of secretagogues?

A

Meglitinides

Sulfonylureas

24
Q

MOA of Meglitinides?

A

Stimulate insulin release from the beta cells in the pancreas

25
Q

What has longer duration of action, Meglitinides or Sulfonylureas?

A

Sulfonylureas-can be given once daily

26
Q

Name 2 Meglitinides

A

Repaglinide (Prandin)

Nateglinide (Starlix)

27
Q

What suffix do most Meglitinides end in?

A

-GLINIDE

28
Q

DDI with Repaglinide (Prandin)? (5)

A 
Gefibrozil
Itraconazole
Clopidogrel (Plavix)
Cyclosporine
Atazanavir (protease inhibitor for HIV treatment)
29
Q

What drug is Repaglinide (Prandin) often combined with?

A

Metformin

30
Q

Dosing consideration for Nateglinide (Starlix)? (1)

A

Must be given before meals

31
Q

MOA Sulfonylureas?

A

Stimulate insulin release from pancreatic beta cells

+/- reduces hepatic glucose output

32
Q

How are second generation Sulfonylureas dosed?

A

Before each meal

33
Q

Give drug names for second 2nd Generation Sulfonylureas? (3)

A

Glimepiride
Glipizide
Glyburide

34
Q

What drug classes are

Non-Secretagogues? (6)

A 
Alpha-glucosidase Inhibitors
Biguanides
DDP-4 Inhibitors
GLP-1 Agonists
SGLT2 Inhibitors
TZD
35
Q

What is the primary function of non-secretagogues?

A

Augment pancreatic insulin

36
Q

MOA of Alpha-glucosidase inhibitors?

A

Delay breakdown of complex carbs and absorption of glucose (work within GI
Tract)

*SLOWS carb digestion and absorption, helping to minimize post-prandial BS spikes

37
Q

How must Alpha-glucosidase inhibitors be dosed?

A

MUST be given with meals (with first bite of food)

38
Q

SE of Alpha-glucosidase inhibitors?

A

GI issues

39
Q

Give drug names for Alpha-glucosidase inhibitors? (2)

A

Acarbose

Miglitol

40
Q

Benefits of alpha-glucosidase inhibitors as a class? (2)

A

No weight gain

No hypoglycemia

41
Q

What effect do alpha-glucosidase inhibitors have on Hbg A1C?

A

Modest reductions (0.5-1%)

42
Q

MOA of Biguanides?

A

Reduce hepatic glucose production (reducing fasting glucose levels)

43
Q

Side effects of biguanides? (2)

A

GI issues

Lactic Acidosis

44
Q

Clinical benefits of Biguanides?

A 
Weight loss
No Hypoglycemia
Improves Insulin Resistance 
Low Cost
Can improve lipid-profile
       -decrease FA & VLDL synthesis from 
        liver, decreasing TG
45
Q

Drug names for Biguanides?

A

Metformin

46
Q

What is the maximum dose for Metformin?

A

2g/day
Can be in divided doses
The higher the dose, the more side effects

47
Q

Contraindications of Metformin? (4)

A

Moderate to severe liver disease
Chronic/Binge ETOH
Pregnancy
Breast Feeding

48
Q

If a patient is taking Metformin, when does the medication need to be held?

A

Renal Failure
Surgery
Anything that may involve IV contrast (stop day of an don’t resume for 48 hours), more of an issue in AKI and risk of higher load contrast

49
Q

What is the effect of Metformin on Hbg A1C?

A

Reduction of 1.5-2.0%

50
Q

Warnings/cautions for use of Metformin? (2)

Address renal dosing (yes or no)

A

Moderate to severe liver disease
Renal Dose adjustments required
Don’t give metformin if GFR <30
Evaluate risk vs benefit if GFR <45
