DM treatment Flashcards
what medication is a biguinaide?
metformin
what is the MOA of metformin?
biguinide
- insulin sensitizer of hepatic and muscle tissues to increase glucose uptake
- lower hepatic glucose production
is metformin associated with hypoglycemia?
no
what is the max effective dose of metformin?
2000mg
what are the ADE of metformin?
N/D/V
metallic taste
interferes with B12 absorption
Lactic acidosis when used with contrast dye
what are the contraindications for metformin?
GFR <30
what are the dose adjustment for GFR when using metformin?
GFR <30: stop therapy
GFR <45: do not initiate therapy
what medications are thiazolinidones?
-glitazones
pioglitazone
rosiglitazone
what is the MOA pioglitazone?
thiazolinidiones
- activates PPAR-y to increase insulin sensitivity
- increase glucose uptake in muscles and adipose tissue
- decrease glucose output by liver
- increase fatty acid uptake
is pioglitazone associated with hypoglycemia?
no
what are the ADE of pioglitazone?
insulin sensitizer
- edema
- HF exacerbation
- increased LFTs
- increased risk of bone fracture
what are the contraindications for pioglitazone?
- NYHA Class III/IV HF
- LFT >2.5x ULN
- Hx of bladder cancer
what medications are sulfonylureas?
Gli- or Gly-
- Glimepiride
- Glipizide
- Glyburide
what is the MOA of sulfonylureas?
Glimepiride, glipizide, glyburide
bind to sulfonylurea receptors on beta cells to increase insulin secretion
- squeeze out insulin
where is significant about Glipizide?
second generation sulfonylurea
- associated with the most hypoglycemia in its class
- metabolized int he liver to inactive metabolites
what is significant about Glimepiride?
2nd gen sulfonylurea
- metabolized in liver to inactive components
- best A1C benefit
- less hypoglycemia, but weight gain
what is significant about glyburide?
2nd gen sulfonylurea
- metabolized in the liver to active metabolites
which of the 2nd gen sulfonylurea is a prodrug?
glyburide
what are the ADE of Glimepiride, glipizide, glyburide?
hypoglycemia
weight loss
pruritis
hemolytic anemia
what is the MOA of nateglinide and repaglinide?
bind to sulfonylyrea receptors on beta cells to increase insulin secretion
- nateglinide and repaglinide
- glimepiride, glipizide, glyburide
both drug classes have the same MOA, what is the difference between the 2?
- nateglinide and repaglinide have a shorter onset
what are the ADE of nateglinide and repaglinide?
- hypoglycemia
- weight gain
what is the MOA of sitagliptin, linaglitin, and alogliptin?
Glucose dependent
- increase insulin synthesis and release from beta cells
- decrease glucagon secretion from alpha cells
out of these meds, which one has no renal adjustments? sitagliptin, linaglitin, and alogliptin
linaglitin
what is the ADE of sitagliptin, linaglitin, and alogliptin?
- acute pancreatitis
- H/A
- severe joint pain
- UTI
- URI
- hypersensitivity
what are the contraindications for sitagliptin, linaglitin, and alogliptin?
- hypersensitivity
- DKA
- Saxgliptin worsens HF
what is the MOA of liragluTIDE, exenaTIDE, exenaTIDE?
- decrease glucagon secretion
- improve satiety and decrease food intake
what are the ADE of liragluTIDE, exenaTIDE, exenaTIDE?
- GI discomfort
- acute pancreatitis
- injection site reaction
- thyroid carcinoma
what are the contraindications for liragluTIDE, exenaTIDE, exenaTIDE?
- hx of thyroid cancer
- MEN2
- risk for thyroid C-cell tumor
what is the MOA of canaGLIFLOZIN, dapaGLIFLOZIN, empaGLIFLOZIN, ertuGLIFLOZIN?
- increase glucose excretion by inhibiting Na+/glucose co-transporter 2 in the proximal convoluted tubule
- lowers renal threshold for glucose
