Question 6

What is the effect on metformin on weight, vascular complications, lipids and risk of hypoglycaemia?

Answer 6

Weight loss
Reduces vascular complications
Lowers lipids
No hypoglycaemic risk

Question 8

Name 3 SUs.

Answer 8

Tolbutamide

Question 9

Which SU reduced microvascular complications?

Answer 9

Glipizide

Question 10

SUs are quicker to resolve hyperglycemia than metformin. True or False?

Answer 10

True

Question 11

How is insulin released then stopped from release from the pancreatic beta cells?

Answer 11

ATP binds to Kir6.1 subunit of KATP channel
Depolarisation causing Ca channel opening
Vesicles bind to cell membrane and release insulin
ADP-MG2+ binds SUR1 subunit of KATP channel to cause closure

How do SUs work?

Answer 12

Displace ADP-Mg2+ from SUR1 to close KATP

Weight gain
No vascular complication reduction
Hypoglycaemia

Answer 15

Hypoglycaemia

SIADH

Question 16

Name a DPP-4i and explain how it works.

Answer 16

Alogliptin

Blocks DPP-4 enzyme which inhibits incretins from stimulating insulin release

Question 17

What is the effect of DPP-4i on weight?

Answer 17

Weight neutral

Question 18

Give 2 examples of incretins + relevance to BG?

Answer 18

GLP-1 and GIP
Increase insulin production
Reduce gluconeogenesis

Question 19

Name a GLP-1 agonists and explain how it works.

Answer 19

Question 21

Name a rare side effect of GLP-1 agonists?

Answer 21

Pancreatitis

Question 22

What is the only thiazolidinedione used in T2DM treatment and how does it work?

Answer 22

Pioglitazone

Forms a PPARgamma-RXR TF for insulin signalling to increase sensitvity

Blocks SGLT2 glucose resorption channel in kidney
Glucosuria

Question 25

What is the effect of SGLTi on weight, hypoglycaemia risk and CVD risk?

Answer 25

Weight loss Hypoglycaemia Reduced CVD risk
