Non-insulin hypoglycemic agents Flashcards
What type of drug are Tolazamide, Chlorpropamide, Acetohexamide?
first generation Sulfonylureas
What are downsides to Acetohexamide, Chlorpropamide, and Tolazamide?
cause hypoglycemia (long half life) possibly toxic to heart
What are Glipizide, Glyburide, and Glimeperide?
Second gen sulfonylureas
-shorter half lives, cause less prolonged hypoglycemia
What are downsides to Glimeperide, glyburide, glipizide?
hypoglycemia, weight gain, cardiac toxicity
hasten demise of beta cell’s insulin producing ability
What are short acting sulfonyl ureas?
Meglitinides
Repaglinide
Nateglinide
What is Metformin?
A Biguanide
-reduces liver production of glucose (through AMPK)
-blocks fatty acid synthesis
increases insulin sensitivity
What is the action of Thiazolidinediones?
PPAR (Peroxisome proliferator activated receptor agonists)
-increase glucose uptake (increased GLUT1, GLUT4)
What is decreased when taking TZDs?
PAI-1, C-reactive protein, inflammatory markers from fat
What class of drug is Pioglitazone and Rosiglitazone?
Thiazolidinediones (TZDs)
What are side fx of TZDs?
weight gain, edema, CHF,
boneloss, bladder tumors (Pioglitazone)
What class of drug is Acarbose?
Alpha-Glucosidase Inhibitors
What do Acarbose/Alpha-Glucosidase Inhibitors do? side fx?
inhibits Alpha-glucosidase (enzyme in intestine needed to break dwon complex starches to glucose)
side fx: flatulence
What are 3 main fx of GLP-1 and GIP?
produced by GI mucosal cells
- Stimulates Insulin Secretion
- Decreases gastric absorption of Glucose
- Decrease glucagon release by pancreatic alpha cells
What is so great about Incretins
insulin levels are only increased in presence of food = no hypoglycemia if you dont eat
What are DPP-4 how can they be applied pharmacologically?
degrades Incretins
Inhibitors of DPP-4 can be used as meds
What drug class are Sitagliptin, Saxagliptin, Linagliptin
DPP-4 inhibitors
What is the mechanism of Canagliflozin, Dapagliflozin, and Empagliflozin?
Inhibits SGLT-2 (sodium-glucose linked transporter in kidney)
- glycosuria and volum recution
- REDUCES CARDIO MORTALITY
What are side fx of SGLT-2 inhibitors?
UTI
Candidal vulvovaginitis and balanitis
Postural hypotension
Lose effectiveness in patient with renal insufficiency
