diabetes drugs Flashcards
metformin class
biguanide
metformin mechanism of action
decreases hepatic glucose production by inhibiting AMP-kinase and mito glycerophosphate dehydrogenase.
metformin benefits.
weight neutral, no hypoglycemia,
there are generics, fewer cardiovascular events and cancer.
metformin disadvantages.
diarrhea, abdominal discomfort. nausea, vomit, anorexia, b12 def.
metformin rare side effect
lactic acidosis
glyburide class
sulfonylurea
glyburide mechanism
closes KATP channels stimulating insulin secretion.
glyburide benefits
well-tolerated, generics available.
glyburide disadvantages
hypoglycemia. weight gain, effects ischemic preconditioning.
why don’t we give sulfonylureas to fat people?
because it increases weight.
glipizide class
sulfonylurea
glipizide mechanism
closes KATP channels stimulating insulin secretion
glipizide advantages
well-tolerated, generics
glipizide disadvantages
weight gain, hypoglycemia. may affect ischemic preconditioning
glimepiride class
sulfonylurea
glimepiride mechanism
closes K-ATP channels stimulating insulin secretion
glimepiride advantages
well-tolerated, generics
glimepiride disadvantages
hypoglycemia, weight gain, preconditioning
repaglinide class
meglitinide
repaglinide mechanism
closes KATP channels stimulates insulin secretion
repaglinide advantages
short-acting, well tolerated.
repaglinide disadvantages
there is hypoglycemia, but less than sulfonylureas. weight gain, dose before each meal.
what classes have the same mechanism? what is the difference
sulfonylurea and maglitinides. mags are shorter acting. must dose before each meal. mags also have less hypoglycemia.
natelglinide class
maglitinide
natelglinide mechanism
closes kATP channels stimulating insulin secretion
natelglinide advantages
short-acting, well-tolerated.
natelglinide disadvantages
weight gain, hypoglycemia, less than sulfonylureas, dose before each meal.
pioglitazone class
thiazolidinediones
pioglitazone mechanism
transcription-factor PPAR-gamma activation. decreases insulin resistance.
pioglitazone advantages
no hypoglycemia, decrease in MI.
pioglitazone disadvantages
weight gain, edema, CHF, bone fractures, macular edema, increase in bladder cancer.
rosiglitazone class
thiazolidinediones
rosiglatazone mechanism
activation of the PPAR-gamma TF. decreases insulin resistance.
rosiglatazone advantages
no hypoglycemia. decrease in MI (only for pio)
rosiglatazone disadvantages
edema, weight gain, CHF, bone fractures, macular edema.
acarbose class
alpha-glucosidase inhibitors.
