anti-diabetic drugs Flashcards
(37 cards)
what is the major stimulus in the regulation of insulin secretion
glucose
incretin hormones in the GI tract stimulate..
the release of insulin when glucose levels are normal or elevated
cortisol, GH, epinephrine, estrogen and progesterone all..
raise blood glucose levels
excessive prolonged endogenous secretion of insulin can exhaust..
pancreatic beta cells and can cause or aggravate DM
some factors that inhibit insulin secretion are?
hypoxia, hypothermia, surgery and severe burns (ie. stress)
DM type 1:
-autoimmune disorder destroys pancreatic beta cells (life long disease)
DM type 2:
-insulin resistance & hyperglycemia
signs and symptoms of DM
-hyperglycemia, glucosuria, polydipsia, polyruia, dehydration, polyphagia
complications of DM include
-MI, Stroke, blindness, leg amputation and kidney failure
lispro and insulin aspart are _________ insulin’s
short acting
intermediate acting insulin’s have
added protamine and or zinc
insulin glargine is _______
long acting, used to provide basal amount
insulin is not used if _____________
DM is controlled by diet
when mixing insulin’s?
draw up rapid/short acting insulin first, then immediate acting insulin, use immediately
the insulin pump uses _______ acting insulin
rapid acting, others use regular insulin
Oral hypoglycemics and anti-hyperglycemics:
sulfonylureas (glyburide)
increase secretion of insulin
Oral hypoglycemics and anti-hyperglycemics:
alpha-glucosidase inhibitors (acarbose)
delay digestion of complex carbohydrates into glucose
Look at videos in red on powerpoint…
YES
Oral hypoglycemics and anti-hyperglycemics:
-Biguanide (ALSO called Metformin)
Increases use of glucose by muscle and fat, decreases hepatic glucose production and decreases intestinal absorption of glucose
Oral hypoglycemics and anti-hyperglycemics:
-Glitazones (Actos)
-insulin sensitizers decrease insulin resistance by stimulating receptors on muscle, fat, and liver cells
Oral hypoglycemics and anti-hyperglycemics:
-Meglitinides (nateglinide)
-stimulate pancreatic secretion of insulin
Oral anti-diabetic agents can be used in various combinations for…
additive fact
Sulfonylureas and meglitinides may have interactions with
beta blockers and alcohol may have additive hypoglycemic effects with concurrent use
concurrent use of thiazide diuretics and _______ may raise blood glucose levels and thereby counteract the effects of insulin
glucocorticoids
