Flashcards in Endocrin Pharm Deck (56)
What are the rapid acting insulins?
Iispro Aspart Glulisine
Mech of lispro aspart glulisine?
Bind insulin receptor (tyrosine kinase activity). Liver: increase glucose stored as glycogen. Muscle: increase glycogen, protein syntesis; increase K+ uptake. Fat: increase TG storage
clinical use of rapid acting insulins
DM1, DM2, GDM (postprandial glucose control)
What are the SE of rapid acting insulins?
hypoglycemia, rare hypersensitivity
What is the insulin, short acting?
What is the clinical use of the regular short acting insulin?
DM1, DM2, GDM, DKA (IV), hyperkalemia (+glucose), stress hyperglycemia.
What is the intermediate acting insulin?
Clinical use of NPH
DM1, DM2, GDM
What are the long acting insulins?
Glargine, Detemir Clinical use?
DM1, DM2, GDM (basal glucose control)
Biguanides (Metformin) mech of action?
Exact mech is unknown. Decreased gluconeogenesis, increased glycolysis, increased peripheral glucose uptake (insulin sensitivity)
Metformin clinical use?
oral. first-line therapy in type 2 DM. Can be used in patients without islet function.
GI upset; most serious adverse effect is lactic acidosis (thus contraindicated in renal failure)
Whatare the first generation sulfonylureas?
What are the second generation Sulfonylureas?
Glyburide, Glimepiride, Glipizide
Close K+ channel in beta cell membrane, so cell depolarizes which triggers insulin release via Ca++ influx
Sulfonylureas clinical use
stimulate release of endogenous insulin in type 2 DM. Require some islet function, so useless in type 1 DM
Risk of hypoglycemia increase in renal failure. First generation: disulfiram-like effects. Second generation: hypoglycemia
What are the Glitazones/thiazolidinediones?
What is the mech of the glitzones/thiazolideinediones?
increase insulin sensitivity in peripheral tissue. binds to PPAR glamma nuclear transcription factor
Clinical use of glitzones/thiazolideinediones?
monotherapy in type 2 DM comined with biguanides, sulfonylureas, or insulins.
SE of glitzones/thiazolideinediones?
weight gain, edema. hepatotoxicity, heart failure.
What are the alpha glucosidase inhibitors
What is the mech of alpha glucosidase inhibitors?
Inhibit intestinal brush border alpha glucosidases. Delayed sugar hydrolysis and glucose absorption which leads to decrease postprandial hyperglycemia.
What is the clinical use of the alpha glucosidase inhibitors?
monotherapy in type 2 DM or in combination with above agents
What are the toxicities of alpha glucosidase inhibitors?
What is the Amylin analog?
Mech of the amylin analog pramlintide?
decrease gastric emptying, decrease glucagon
Clinical use of the amylin analog pramlintide?
Type 1 DM and Type 2 DM
