Q

What type of antihyperglycemic is metformin and what is its MOA?

(How it glucose output and uptake)

A
  • biguanide
  • decreases glucose output in liver
  • increases insulin sensitivity on muscles and fat to increase uptake

Q

Name two thiazolidinediones that work on the PPAR (Preoxisome proliferator activated receptor) and list their MOA, side effects and toxicities

(Works on gene transcription)

A
  • rosiglitazone, pioglitazone
  • MOA:PPAR agonist to increase gene transcription
  • Increases glut-4 transporters, lipoprotein lipase, fatty acid transporters
  • Side Effects: weight gain and fluid retention

Q

Name two thiazolidinediones that work on the GLP-1 (glucagon-like peptide 1) and list their MOA, route of administration and toxicities

A
  • Liraglutide, Exenatide
  • MOA: GLP-1 receptor agonist, inhibits glucagon secretion, increases insulin secretion (incretin mimetic)
  • given subcutaneously
  • Common toxicities: nausea, diarrhea, vomiting
  • Serious toxicities: pancreatitis, thyroid carcinoma (liraglutide), anaphylactic reaction (exenatide)

Q

Name three thiazolidinediones that work on the DPP-4 (dipeptidyl peptidase 4) and list their MOA and toxicities

A
  • Sitagliptin, Saxafliptin, Linagliptin
  • MOA: DPP-4 inhibitor blocks breakdown of GLP-1. Increases duration of incretin, stimlulates insulin release and inhibits glucagon
  • Common Toxicities: Upper respiratory infection, nasopharyngitis, headache
  • Serious Toxicities: Pancreatitis, hypersensitive reactions

Q

what is a new MOA for prevent reabsorption of glucose. (MOA)

A
  • inhibit type 2 sodium-glucose transporter

- prevents reabsoption of glucose in kidneys and keeps blood glucose low
