pioglitazone (Actos)

29
Q

how does pioglitazone (Actos) fxn?

A

Thiazolidinediones (TZD) or “glitazones”

Work by (1) decreasing insulin resistance and (2) suppress glucose production by the liver

A

heart failure

32
Q

prototype for Alpha-glucosidase Inhibitors

A

acarbose (Precose)

33
Q

how does acarbose (Precose) fxn?

A

Alpha-glucosidase Inhibitors

Slows digestion of starches in the gut by blocking enzyme that breaks down starches
• “a” “carb” “ohhhh”

34
Q

side effects of acarbose (Precose)

◦ GI (abdominal cramping, diarrhea, flatulence, borborygmus)
◦ Long term: liver dysfunction

i LIVE(r) for Carbs

35
Q

when do we take acarbose (Precose) in relation to food?

A

Take with first bite of food!

36
Q

Does acarbose (Precose) have risk for hypoglycemia?

A

monotherapy = no

w/ insulin or sulfonylurea Glipizide = risk of hypogly

37
Q

if you have hypoglycemia with acarbose (Precose) how do you treat it?

A

oral glucose (sucrose will NOT work)

38
Q

prototype for SGLT-2 Inhibitors

A

canagliflozin (Invokana)

So (much) Glucose Leaving (my) Tubes –> Kidneys

39
Q

how does canagliflozin (Invokana) fxn?

A

Increases glucose secretion through urine by inhibiting SGLT-2
-work on kidney

40
Q

admin/route for canagliflozin (Invokana)

A

pill Q daily

41
Q

side effects of canagliflozin (Invokana) (regular and serious)

A

Side Effects: Genital fungal infections, UTI and increased urination, Weight loss

Serious Side Effects: DKA, urosepsis, pyelonephritis, increased risk of amputation

***watch for signs of dehydration

42
Q

what are incretins? what do they do? (6)

A

hormones secreted by the intestine following a meal when bld glucose is elevated.
• signal the pancreas to increase insulin section
• signal the liver to stop producing glucagon
• Slow gastric emptying
• Stimulate insulin release from pancreas
• Inhibit postprandial release of glucagon
• Suppress appetite

43
Q

prototype for GLP-1 Receptor Agonist/Mimetics

A

Exanatide (Byetta)

44
Q

how does Exanatide (Byetta) fxn?

A

synthetic GLP-1 that mimics the action of incretins

actions of incretins:
• signal the pancreas to increase insulin section
• signal the liver to stop producing glucagon
• Slow gastric emptying
• Stimulate insulin release from pancreas
• Inhibit postprandial release of glucagon
• Suppress appetite

45
Q

when do we give Exanatide (Byetta) in relation to food? (route?)

52
Q

how does Sitagliptin (Januvia)fxn?

A

enhances the action of incretin hormones

actions of incretin hormone:
• signal the pancreas to increase insulin section
• signal the liver to stop producing glucagon
• Slow gastric emptying
• Stimulate insulin release from pancreas
• Inhibit postprandial release of glucagon
• Suppress appetite

53
Q

patients do not have to be able to make insulin to use sitagliptin- true or false

A

FALSE

actions of Sitagliptin (incretin hormone enhancer) are dependent on insulin :: patient must be able to make some insulin

regular and rare side effects of sitagliptin

A

DPP-4 Inhibitors

Side effects: cold symptoms
Rare Side Effects: pancreatitis, hypersensitivity reactions

55
Q

admin for Sitagliptin (Januvia)- food? frequency?

A

One pill once a day with/without food

56
Q

prototype for Amylin Mimetics

A

Pramlintide (Symlin)

57
Q

how does Pramlintide (Symlin) fxn?

A

amylin mimetic

co released w/ insulin
• Delays gastric emptying
• Suppresses glucagon secretion
• Decreases postprandial glucose elevation

58
Q

Pramlintide (Symlin) for type 1 or 2 DM?

A

both!

Amylin Mimetic

59
Q

when do we take Pramlintide (Symlin) in relation to food? how do we admin?

A

Taken at meals SQ, Can’t be mixed in syringe with insulin

60
Q

consideration for other oral meds with Pramlintide (Symlin)

A

Take any oral drugs 1 hour before injection

61

will Pramlintide (Symlin) cause hypoglycemia?

A

only if used w/ insulin

occurs within 3 hours of injection !

63

3 DM drugs for preggos?

A
  • NPH/Regular insulin
  • Glargine (Lantus)/ aspart (Novalog)
  • Metformin (Glucophage)
64
Q

initially treat hypoglycemia with….

A

• Food: 15G carbohydrates
◦ Glucose tablets, 120 cc OJ or non diet soda, 3-4 pieces candy, 1 TBSP sugar
• Administration of D50 (Dextrose 50%) IV – irritating to veins
