Make sure to check blood glucose and LFTs

22
Q

Name a Thiazolidinediones (TZDs/ Glitazones)

A

Pioglitazone

23
Q

MoA of Thiazolidinediones

A
  • activate PPARs (peroxisome proliferator-activated receptors) that then increase peripheral glucose uptake
  • inhance action of insulin

Q

Side effects of TZDs

A

Weight gain
Hepatotoxic
Water retention (don’t use in Heart failure)
Increased fracture risk

MoA of Glucagon-like-peptide-1 agonsits

A
  • increase insulin secretion
  • early satiety (decreased gastric empting)
  • reduces appetite through hypothalamic action
27
Q

Side effects of Glucagon-like-peptide-1 agonsits

A

Pancreatitis / Pancreatic cancer

28
Q

Name some Dipeptide peptidase 4 inhibitors (DPP-IV inhibitors)

A
Sitagliptin
Saxagliptin 
Vildagliptin
