What chronic disease can cause a falsely elevated HbA1C level?
Sickle cell anemia
What can cause a falsely low HbA1C level?
Blood transfusion
What is the suffix of the Na/glucose transporter inhibitors?
“-flozin”
What are the two GLP-1 agonists? MOA?
Exenatide
Liraglutide
Increases insulin, decreases glucagon release
What are the DPP-4 inhibitors? MOA?
“-gliptins”
inhibits the breakdown of GLP-1
Increases insulin release
Decreases glucagon release
What percent of body weight was lost with the DPP lifestyle change group?
7%
What is the MOA of acarbose?
alpha-glucosidase inhibitor
What is the MOA of miglitol?
alpha-glucosidase inhibitor
What are the two alpha-glucosidase inhibitors?
Miglitol
Acarbose
What is the biguanide that is used in the treatment of DM II?
Metformin
What type of drug is Metformin?
Biguanide
What are the two first generation sulfonylureas?
Tolbutamide
Chlorpropamide
What are the three second generation sulfonylureas?
Glyburide
Glimepiride
Glipizide
What type of drug is pramlintide? MOA? Side effects?
- Amylin analog
- Decreases gastric emptying
- Decreases glucagon production
What is incretin and what does it do? What drugs mimic this?
a group of metabolic hormones that stimulate a decrease in blood glucose levels. Incretins do so by causing an increase in the amount of insulin released from pancreatic beta cells of the islets of Langerhans after eating, before blood glucose levels become elevated
GLP-1 analogs
DPP-4 inhibitors
What is amylin, and what does it do? What medication mimics this?
Peptide hormone that is secreted with insulin to slow gastric emptying
DPP-4 inhibitor
What type of drugs are the best option for pts who have a mild postprandial hyperglycemia?
alpha-glucosidase inhibitors
What is the MOA of metformin? Side effect?
Decreases gluconeogenesis
GI upset and lactic acidosis
What what pts is metformin contraindicated?
CKD
What is the MOA of thiazolidinediones? What is the major side effect seen with this drug?
PPAR-gamma agonists, which increases insulin sensitivity in peripheral tissues
Weight gain/edema
Hepatotoxic
What are the two thiazolidinediones?
Pioglitazone
Rosiglitazone
What is the suffix that denotes the thiazolidinediones?
“-azone”
In whom are incretin mimetics (GLP-1 and DPP 4 inhibitors) contraindicated?
CKD
What DM med aids with weight loss?
GLP-1 analogs
What is the major contraindication to pramlintide?
Someone who already has gastroparesis
