Diabetes Drugs Flashcards
Acarbose
alpha-glucosidase inhibitor
Alpha-glucosidase inhibitors work by
Decreasing upper GI absorption of glucose, decreasing post-meal hyperglycemia
*Inhibits breakdown of complex polysaccharides
Pioglitazone
thiazolidinedione
Thiazolidinediones work by
enhancing effects of insulin, enhance fat storage
*Peroxisome proliferator activated receptor gamma agonist
Side effects of thiazolidinediones
Weight gain, fluid retention (don’t use with HF)
Sulfonylureas mechanism of action
Works independent of glucose, binds and opens ATP sensitve K+ channel. Depolarize cell membrane, leading to calcium influx and insulin release.
*Take with food, may cause hypoglycemia
List three sulfonylureas
Glipizide, glimepiride, glyburide
GLP-1 agonist mechanism
bind to GLP-1 receptor on Beta-cell and stimulate insulin secretion. Requires glucose to cause depolarization/calcium influx and initiate insulin secretion cascade
Exenatide and liraglutide are
GLP-1 agonists
*May cause weight loss (5lbs due to slowed gastric emptying, nausea), pancreatitis
DPP-IV inhibitors work by
*dipeptidyl peptidase IV breaks down GLP-1
Making endogenous GLP-1 last longer
Sitagliptin, saxagliptin, linagliptin are
DPP-IV inhibitors
*does not cause weight loss, otherwise similar side effects to GLP-1 agonist
SGLT-2 inhibitors mechanism of action
SGLT-2 is expressed in proximal renal tubule, mediates reabsorption of 90% filtered glucose load. SGLT-2 inhibitors promote renal excretion of glucose
Canaglifozin is a
SGLT-2 inhibitor
Side effects include: weight loss, vulvovaginal candidiasis, UTIs, Ketoacidosis cases
