Endo Pharm Flashcards
What is the tx strategy for type II diabetic patients?
Diet modification
Exercise/ weight loss
Oral hypoglycemics
Insulin replacement (end-stage)
What is the treatment strategy for a type I diabetic?
Low sugar diet and insulin replacement
What is the MOA of insulin?
Bind insulin receptor - tyrosine kinase activity
Causes increased glucose storage as glycogen in liver, muscle
Increased protein synthesis
Potassium uptake (forces potassium into the cells)
Aids in TG storage
What are the rapid acting insulins?
Lispro
Aspart
Glulisine
What is the intermediate acting insulin?
NPH
What are the long acting insulins?
Glargine
Detemir
What are the toxicities of insulin?
Hypoglycemia
Hypersensitivity
What is the action of biguanides?
Decrease gluconeogenesis
Increase glycolysis
Increase peripheral glucose uptake
What are biguanides used for?
First line for Type II
What is the tox of biguanides?
GI upset Lactic acidosis (CI in renal failure)
What is the MOA of sulfonylureas?
Close K channel in beta cell membrane so cell depolarizes and insulin is released via calcium influx
What are sulfonylureas used for?
Stimulate release of insulin in Type II
Requires some islet fxn
What are the side effects of first gen sulfonylureas?
Disulfiram-like effects
What are the first gen sulfonylureas?
Tolbutamide
Chlorpropamide
What are the second gen sulfonylureas?
Glyburide
Glimepiride
Glipizide
What is the tox in second gen sulfonylureas?
Hypoglycemia
What is the MOA of glitazones?
Increase insulin sensitivity in peripheral tissue
Binds PPAR-gamma nuclear transcription regulator
What are glitazones used for?
Used as monotherapy in type II
What is the tox in glitazones?
Weight gain
Edema
Hepatotoxicity
Heart failure
What is the MOA of alpha glucosidase inhibitors?
Inhibit intestinal brush border alpha glucosidase
Delay sugar hydrolysis and glucose absorption so it decreases postprandial hyperglycemia.
What are the alpha glucosidases?
Acarbose
Miglitol
What are alpha glycosidase inhibitors used for?
Monotherapy type II
What is the tox of alpha glucosidase inhibitors?
GI disturbances
