Q

what is the concern with oral diabetic medications and illness

A

may need to switch to insulin during acuted infection because they potentially will have wose glucose control. Also prior to inpatient surgery

if they become pregnant or develop gestation diabetes to maintain tighter glucose control.

27
Q

what oral diabetic drug dose not cause hypoglycemia when used alone

A

biguanide -metformin/ alpha glucosidase inhibitors - acarbose

28
Q

what 2 oral drugs can cause hypoglycemia

A

secreatagogues: sulfonylureas and meglitinides

29
Q

would metformin or a sulfonylurea cause weight loss

A

metformin about 4-7 lbs

30
Q

what is the vitain B12 deficiency offten associated with

A

metformin

31
Q

what drug has severe sideefect lactic acidosis

A

metformin a biguanide

32
Q

who should not be on metformin

A

those with impaired renal function

33
Q

how does sulfonylurease cause insulin release

A

partial blocking of potassium channels increasing Ca release stage that signals insulin release

34
Q

what generation of sulfonylureases are most often used

A

2nd generation Glipizide

35
Q

most concerning about sulfonylureas

A

hypoglycemia and then there is often weight gain and lose effectiveness withing 5-10 years

36
Q

which sulfonylureas is most likely to cause hypoglycemia

A

gyburide

37
Q

how often dose metformin

A

twice daily

38
Q

how often dose glipizide

A

one morning dose

39
Q

what are the two meglitinides secretagogues

A

nateglinide and repaglinide which is more effective

40
Q

what drug class would you not want to mix meglitinides with

A

sulfonylureas because it would increase risk of hypoglycemia

41
Q

how often are meglitinies taken

A

3-4 times a day unlike sulfonylureas which are once in the morning

42
Q

how often are the glitazones dosed

A

1-2 times each

43
Q

what are the two glitazones

A

glitazones: avandia and actos

44
Q

which of the glitazones may be used with insulin

A

ACTOS only

45
Q

what is concerning about glitazones

A

they increase risk of CHF and possibly MI, increased ALT and wt tain

46
Q

what diabetic drug must you test liver function

A

glitazones: avandia and actos

47
Q

what are the two a glucosidase inhibitors

A

a-glucosidase inhibitors: Acarbose and miglitol

48
Q

when are the a-glucosidase inhibitors taken

A

with each meal,

49
Q

when would acarbose and miglitol cause hypoglycemia

A

only if combined with sulfonylurea or insulin, never if given alone

50
Q

side effects of A glucosidase inhibitors

A

flatulance abd pain, diarrhea because it works at GI brush border

51
Q

what drug has a rare fatal hepatic failure

A

Acarbose: aglucosidase inhibitor

52
Q

what is unique about hypoglycemia of those on a glucosidase inhibitos

A

The antadote is Glucose and can not be sucrose.

53
Q

who can not take acarbose or miglitor:aglucosidase inhibitor

A

those with chronic intestinal diseases or obstruction

54
Q

what does preservation o GLP and GIPdo

A

DDP-4:drive blood glucose to normal to lower insulin release and glucagon supression reducing risk o hypoglyemia

55
Q

what is a DPP inhibitor

A

Sitagliptin/januvia: potientiate insulin effects so it is never used with insulin

56
Q

what of the oral diabetic drugs are never used with insulin

A

Sitagliptin/januvia: DPP-4 inhibitors

57
Q

what drugs can cause increase of pancreantitis

A

DPP-4 inhibitrs: Sitagliptin/januvia and janumet

58
Q

what is the good first choice drug

A

Metformin: Biguanides, then ad sulfonylurea if that diesn’t work.

59
Q

what are the two injectable DM type II drugs

A

Pramlintide and exenatide

60
Q

Pramlintide/symlin: injectable

A

Synthetic amylin - produced with insulin by beta cells, so can used less insulin while stil lowering average blood sugar

61
Q

Exenatide : injectable

A

syntehtic extendin -4 - gila monster saliva

62
Q

can pramlintide be used with insulin?

A

Yes but they can not be injected inside the same vial or syringe.

63
Q

why is pramlintide notable

A

first approved to lower blood sugar in diabetics since discovery of insulin

64
Q

why is pramalintide injected

A

at meals times, without causing wt gain or hypoglycemia although nausea is a side effect.

65
Q

incretin mimetics

A

Incretin mimetics: exenatide/byetta, lowers blood blucose by increasing insulin secretion

66
Q

what is unique about exenatides ability to lower blood glucose levels

A

it only lowers blood blucose in presence of high bloodglucose, so hypoglycemia is not a risk.
