Q

If after first line for t2dm (and no ASCVD, HF or CKD), A1c is still not at target what is the first thought? What to do with that ?

16
Q

MOA of biguanides

A

decrease hepatic glucose production, decrease intestinal absorption of glucose, improve insulin sensitivity

17
Q

eGFR needs to be ___ to use biguanides.

A

> 45
if 30-45, don’t start but if continued, reduce dose by 50%
<30-> contraindicated

18
Q

The metformin AEs are

A

predominantly GI, metallic taste, B12 deficiency, lactic acidosis

19
Q

What are the sulfonylreas used?

A

glimepiride, glipizide, glyburide

20
Q

MOA of sulfonylureas

A

stimulate insulin release from β cells, reduce glucose output from liver, increase insulin sensitivity at peripheral target sights

21
Q

What are safety concerns with SUs

A

may be associated with increased CV mortality

can’t use with sulfonamide allergy

22
Q

What are adverse effects of SUs

A

hypoglycemia (glyburide not recommended)
increased risk of C
weight gain

23
Q

What are the thiazolidinediones used

A

pioglitazone

rosiglitazone is discontinued

24
Q

Thiazolidinedione MOA

A

peroxisome proliferator-activated receptor γ agonist-> influences production of things involved in glucose/lipid metabolism

25
Q

TZDs are not recommended in individuals with

A

renal impairment from fluid retention. Heart failure

bladder cancer, increased LDL cholesterol, bone fractures

26
Q

What are the Dipeptidyl Peptidase-IV

A

alogliptin, linagliptin, saxagliptin, sitagliptin

27
Q

What is the renal constrictions with sitagliptin

A

CrCl<50-> only 50mg PO daily

28
Q

DDP-IV MOA

A

inhibit DDP-4 enzyme-> prolong incretin (GLP-1)-> released in response to meal-> up insulin synthesis and release from β cells, decreased glucagon secretion from α cells

29
Q

Renal dose adjustment is needed in these three DDP-4 inhibtors

A

sitagliptin, saxagliptin, alogliptin (no dose adjustment for linagliptin)

30
Q

DDP4 inhibitors interact with

A

CYP3A4

31
Q

DDP4 AEs

A

acute pancreatitis, joint pain, increased risk of HF exacerbations

32
Q

FDA approved GLP-1 agonists

A

semaglutide, lixisenatide, dulaglutide, liraglutide, exenatide

33
Q

GLP1 agonist MOA

A

enhance glucose dependent insulin secretion. slows gastric emptying.

34
Q

Don’t prescribe GLP-1 agonists in people with

A

hx of pancreatitis, c-cell thyroid cancer, multiple endocrine neoplasia syndrome type 2 (MEN2)

35
Q

What are AEs of GLP-1 agonists

A

GI side effects (N/V, diarrhea), injection site, acute pancreatitis risk?

36
Q

SGLT2 inhibitor MOA

A

inhibits reabsorption of filtered glucose and lower renal threshold for glucose by inhibit SGLT2 in proximal renal tubules

37
Q

Don’t use SGLT2 inhibitors in individuals with

A

Hx of DKA, amputations, frequent UTIs, severe renal impairment (ESRD, dialysis)

38
Q

AEs of SGLT2 inhibitors

A

bone fractures, DKA, GI/GU infections, UTIS, risk hypotension, Fournier’s gangrene, amputation risk for canagliflozin

39
Q

Bypass the algorithm and just give insulin if

A

a1c>9 and need to get it down fast

or someone comes in with catabolic features (weight loss, ketosis)
