Q

What is drug is first line for DM2?

A

Metformin

2
Q

How does metformin work?

A

Increases sensitivity to insulin & decreses glucose production in the liver

3
Q

What are is the most common reason for people not tolerating metformin?

A

GI upset

4
Q

When is metformin contraindicated?

A

In renal failure & AKI

5
Q

A

Swallow tablets whole with a glass of water with or after food

6
Q

What can help if someone is experiencing GI upset on metformin?

A

Changing to a modified-release preparation

7
Q

A

Sulphonylurea (SU)

8
Q

Give 2 examples of SUs

A

Glicazide & glimepiride

9
Q

How do SUs work?

A

Stimulate pancreatic insulin secretion

10
Q

What are three side effects of SUs?

A

Hypoglycaemia
Weight gain
GI upset (usually mild & infrequent)

11
Q

What are options for additional drugs (e.g. used in triple therapy)

A
Gliptins (DPP-4 inhibitors)
Pioglitazone
SGLT-2 inhibitors
GLP-1 Agonist
Insulin
12
Q

Give two examples of gliptins (DPP-4 inhibitors)

Which one is safe in renal impairment?

A

Linagliptin (safe in renal impairment)

Sitagliptin

13
Q

How do gliptins (DPP-4 inhibitors) work?

A

Increase insulin secretion and decrease glucagon secretion (so reduce glycogen breakdown)

14
Q

What are 2 side effects of gliptins (DPP-4 inhibitors)?

A

Pancreatitis

Weight loss

15
Q

How does pioglitazone work?

A

Preserves B cell function & reduces insulin resistance

16
Q

What type of cancer is pioglitazone associated with?

A

Bladder cancer

17
Q

When is pioglitazone contraindicated?

A

Heart & liver failure

Bladder cancer

18
Q

What is a side effect of pioglitazone?

A

Increased risk of long bone fractures

19
Q

How do SGLT2 inhibitors work?

A

Increase resabsorption of glucose, therefore increase glucose excretion in urine

20
Q

A

Thrush
UTI
Weight loss

21

22
Q

23
Q

How do GLP-1 agonists work?

S/C injection

25
Q

What is a side effect of GLP-1?

A

weight loss

26
Q

When would you consider adding insulin?

A

If HbA1c still not well controlled/ Beta cell failure

27

Pioglitazone (due to water retention)

Sulfonlyureas

Insulin

28
