17
Q

what are the benefits of incretin analogues

A

moderate weight loss
prevent hypo
reduce hepatic fat

18
Q

what is the mechanism of Thiazolidinediones

A

enhance insulin action at target tissues but does not affect insulin secretion

19

list some examples of TZDs

A

pioglitazone

rosiglitazone

20
Q

what are the side effects of TZDs

A

weight gain
fluid retention
increased risk of fracture

21
Q

TZDs are contraindicated in what diseases

A

heart failure due to fluid retention

22
Q

what is the mechanism of action of SGLT-2 inhibitors

A

reduce renal tubular reabsorption of glucose therefore you pee out more sugar

thrush
UTIs
joint pain
